How I can parse pipeline sign from fields in xslt. e.g.
dummy1|dummy2|dummy3|dummy4
Regards,
Sarah
If you use an XSLT 2.0 processor you can use the tokenize function (http://www.w3.org/TR/xpath-functions/#func-tokenize) e.g. with an input of
<foo>dummy1|dummy2|dummy3|dummy4</foo>
you can match
<xsl:template match="foo">
<xsl:value-of select="tokenize(., '\|')"/>
</xsl:template>
to output dummy1 dummy2 dummy3 dummy4. If you use an XSLT 1.0 processor you can check whether it supports an extension function like http://www.exslt.org/str/functions/tokenize/ or you need to write a recursive, named template splitting up the input.
In xlst 1.0 I usually use recursive call of named template, e.g.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:variable name="dummyVar" select="'dummy1|dummy2|dummy3|dummy4'" />
<xsl:variable name="delimiter" select="'|'" />
<xsl:template match="/">
<dummies>
<xsl:call-template name="parseDummy">
<xsl:with-param name="parsedString" select="$dummyVar" />
</xsl:call-template>
</dummies>
</xsl:template>
<xsl:template name="parseDummy">
<xsl:param name="parsedString" />
<xsl:choose>
<xsl:when test="contains($parsedString, $delimiter)">
<xsl:element name="{substring-before($parsedString, $delimiter)}" />
<xsl:call-template name="parseDummy">
<xsl:with-param name="parsedString" select="substring-after($parsedString, $delimiter)" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:element name="{$parsedString}" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
It's on you what you need to do with parsed values, in example I construct elements with names of dummies.
Be careful about context which is changing.

Can any guide me to split the given xml element values into multiple child elements based on a token. Here is my sample input xml and desired output. I have a limitation to use xsl 1.0. Thank you.
Input XML:
<?xml version='1.0' encoding='UTF-8'?>
<SQLResults>
<SQLResult>
<ACTION1>Action1</ACTION1>
<ACTION2>Action2</ACTION2>
<Encrypt>Program=GPG;Code=23FCS;</Encrypt>
<SENDER>Program=WebPost;Protocol=WS;Path=/home/Inbound</SENDER>
</SQLResult>
</SQLResults>
Output XML:
<?xml version='1.0' encoding='UTF-8'?>
<SQLResults>
<SQLResult>
<ACTION1>Action1</ACTION1>
<ACTION2>Action2</ACTION2>
<Encrypt>
<Program>GPG</Program>
<Code>23FCS</Code>
</Encrypt>
<SENDER>
<Program>Action4</Program>
<Protocol>WS</Protocol>
<Path>/home/Inbound</Path>
</SENDER>
</SQLResult>
</SQLResults>
In XSLT 2 it would be easy, just with the following template:
<xsl:template match="Encrypt|SENDER">
<xsl:copy>
<xsl:analyze-string select="." regex="(\w+)=([\w/]+);?">
<xsl:matching-substring>
<element name="{regex-group(1)}">
<xsl:value-of select="regex-group(2)"/>
</element>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:copy>
</xsl:template>
Because you want to do it in XSLT 1, you have to express it another way.
Instead of analyze-string you have to:
Tokenize the content into non-empty tokens contained between ; chars.
You have to add tokenize template.
Each such token divide into 2 substrings, before and after = char.
Create an element with the name equal to the first substring.
Write the content of this element - the second substring.
XSLT 1 has also such limitation that the result of the tokenize template
is a result tree fragment (RTF) not the node set and thus it cannot be
used in XPath expressions.
To circumvent this limitation, you must use exsl:node-set function.
So the whole script looks like below:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:exsl="http://exslt.org/common">
<xsl:output method="xml" encoding="UTF-8" indent="yes" />
<xsl:strip-space elements="*"/>
<xsl:template match="Encrypt|SENDER">
<xsl:copy>
<xsl:variable name="tokens">
<xsl:call-template name="tokenize">
<xsl:with-param name="txt" select="."/>
<xsl:with-param name="delim" select="';'"/>
</xsl:call-template>
</xsl:variable>
<xsl:for-each select="exsl:node-set($tokens)/token">
<xsl:variable name="t1" select="substring-before(., '=')"/>
<xsl:variable name="t2" select="substring-after(., '=')"/>
<xsl:element name="{$t1}">
<xsl:value-of select="$t2" />
</xsl:element>
</xsl:for-each>
</xsl:copy>
</xsl:template>
<xsl:template name="tokenize">
<xsl:param name="txt" />
<xsl:param name="delim" select="' '" />
<xsl:choose>
<xsl:when test="$delim and contains($txt, $delim)">
<token>
<xsl:value-of select="substring-before($txt, $delim)" />
</token>
<xsl:call-template name="tokenize">
<xsl:with-param name="txt" select="substring-after($txt, $delim)" />
<xsl:with-param name="delim" select="$delim" />
</xsl:call-template>
</xsl:when>
<xsl:when test="$txt">
<token><xsl:value-of select="$txt" /></token>
</xsl:when>
</xsl:choose>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy><xsl:apply-templates select="#*|node()"/></xsl:copy>
</xsl:template>
</xsl:transform>
I have a variable as below:
<xsl:variable name="ARRAY">
One,Two,Three,Four
</xsl:variable>
With XSLT 2.0 I used tokenize functions and I set an array variable:
<xsl:variable name="tokenizedSample" select="tokenize($ARRAY,',')"/>
and get array value with:
<xsl:value-of select="$tokenizedSample[1]"/>
Unfortunately I must use XSLT 1.0 and I don't know as replace this situation...
I found some examples to create a template as below:
<xsl:template name="SimpleStringLoop">
<xsl:param name="input"/>
<xsl:if test="string-length($input) > 0">
<xsl:variable name="v" select="substring-before($input, ',')"/>
<field>
<xsl:value-of select="$v"/>
</field>
<xsl:call-template name="SimpleStringLoop">
<xsl:with-param name="input" select="substring-after($input, ',')"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
and calling this template as below:
<xsl:variable name="fields">
<xsl:call-template name="SimpleStringLoop">
<xsl:with-param name="input" select="$ARRAY"/>
</xsl:call-template>
</xsl:variable>
and accessing to this new array with:
<xsl:value-of select="$fields[1]"/>
but doesn't work.
How can I do?
I would like a XSLT 1.0 variable as array because I want read it with for example:
$newArray[1]
Thanks.
I don't see why you would define a variable that needs tokenizing, instead of defining it as "tokenized" to begin with.
In XSLT 1.0, this could be done as:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:my="http://www.example.com/my"
exclude-result-prefixes="my">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<my:items>
<item>One</item>
<item>Two</item>
<item>Three</item>
<item>Four</item>
</my:items>
<!-- the rest of the stylesheet -->
</xsl:stylesheet>
With this in place, you can do:
<xsl:value-of select="document('')/xsl:stylesheet/my:items/item[2]"/>
from anywhere in your stylesheet to retrieve "Two".
Of course, you could put the "array" into a variable:
<xsl:variable name="my-items" select="document('')/xsl:stylesheet/my:items/item" />
so that you can shorten the reference to:
<xsl:value-of select="$my-items[2]"/>
As part of an XSLT, I need to add all the values of the "Duration" element and display the value. Now, the below XML is a part of the larger XML I'm working on. In the below XML, I need to match
a/TimesheetDuration/Day*/Duration, add the values and display them. I dont want to store all the values in variables and add them. Is there any other clean way of doing this?
<?xml version="1.0" ?>
<a>
<TimesheetDuration>
<Day1>
<BusinessDate>6/12/2013</BusinessDate>
<Duration>03:00</Duration>
</Day1>
<Day2>
<BusinessDate>6/13/2013</BusinessDate>
<Duration>04:00</Duration>
</Day2>
<Day3>
<BusinessDate>6/14/2013</BusinessDate>
<Duration>05:00</Duration>
</Day3>
</TimesheetDuration>
</a>
An XPath 2.0 solution, assuming the durations are in the form HH:MM, would be
sum(for $d in a//Duration
return xs:dayTimeDuration(replace($d, '(..):(..)', 'PT$1H$2M')))
In xslt 1.0 you could do it for example with following stylesheet
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<Durations>
<xsl:apply-templates select="a/TimesheetDuration/node()[starts-with(name(),'Day')]" />
<xsl:variable name="hours">
<xsl:call-template name="sumHours">
<xsl:with-param name="Day" select="a/TimesheetDuration/node()[starts-with(name(),'Day')][1]" />
</xsl:call-template>
</xsl:variable>
<SumOfHours>
<xsl:value-of select="$hours" />
</SumOfHours>
<!-- Sum of minutes would be calculated similarly -->
</Durations>
</xsl:template>
<xsl:template match="node()[starts-with(name(),'Day')]">
<xsl:copy-of select="Duration" />
</xsl:template>
<xsl:template name="sumHours">
<xsl:param name="tmpSum" select="0" />
<xsl:param name="Day" />
<xsl:variable name="newTmpSum" select="$tmpSum + substring-before($Day/Duration, ':')" />
<xsl:choose>
<xsl:when test="$Day/following-sibling::node()[starts-with(name(),'Day')]">
<xsl:call-template name="sumHours">
<xsl:with-param name="tmpSum" select="$newTmpSum" />
<xsl:with-param name="Day" select="$Day/following-sibling::node()[starts-with(name(),'Day')]" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$newTmpSum" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
It produces output
<?xml version="1.0" encoding="UTF-8"?>
<Durations>
<Duration>03:00</Duration>
<Duration>04:00</Duration>
<Duration>01:00</Duration>
<SumOfHours>8</SumOfHours>
</Durations>
can I use max function in a variable in XSLT 1?
I need to find a maximum value inside some nodes and I'll need to call this from more places.
So I tried to create a template:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:essox="urn:essox-scripts">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template name="Field001_max_dluznych_splatek">
<xsl:param name="CrRep"/>
<xsl:variable name="PocetDluznychSplatekSplatky">
<xsl:value-of
select="max($CrRep
/Response
/ContractData
/Installments
/InstDetail
/NrOfDueInstalments)" />
</xsl:variable>
<xsl:variable name="PocetDluznychSplatekKarty">
<xsl:value-of
select="max($CrRep
/Response
/ContractData
/Cards
/CardDetail
/NrOfDueInstalments)" />
</xsl:variable>
<xsl:choose>
<xsl:when test="$PocetDluznychSplatekSplatky
>= $PocetDluznychSplatekKarty">
<xsl:value-of select="$PocetDluznychSplatekSplatky"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$PocetDluznychSplatekKarty"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
In XML Spy I get this error:
Error in XPath expression Unknown
function - Name and number of
arguments do not match any function
signature in the static context -
'max'.
What is wrong?
Thanks a lot,
Peter
Use the well known maximum idiom:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:essox="urn:essox-scripts">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template name="Field001_max_dluznych_splatek">
<xsl:param name="CrRep"/>
<xsl:variable name="PocetDluznychSplatekSplatky">
<xsl:call-template name="maximun">
<xsl:with-param name="pSequence"
select="$CrRep
/Response
/ContractData
/Installments
/InstDetail
/NrOfDueInstalments"/>
</xsl:call-template>
</xsl:variable>
<xsl:variable name="PocetDluznychSplatekSplatky">
<xsl:call-template name="maximun">
<xsl:with-param name="pSequence"
select="$CrRep
/Response
/ContractData
/Cards
/CardDetail
/NrOfDueInstalments"/>
</xsl:call-template>
</xsl:variable>
<xsl:choose>
<xsl:when test="$PocetDluznychSplatekSplatky
>= $PocetDluznychSplatekKarty">
<xsl:value-of select="$PocetDluznychSplatekSplatky"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$PocetDluznychSplatekKarty"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template name="maximun">
<xsl:param name="pSequence"/>
<xsl:for-each select="$pSequence">
<xsl:sort select="." data-type="number" order="descending"/>
<xsl:if test="position()=1">
<xsl:value-of select="."/>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Note: In a named template for reuse.
There is no max function in XSLT 1.0. You can work around this by sorting your elements in descending order and then taking the value of the first one.
Here's another (slower) way to do it:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:variable name="PocetDluznychSplatekSplatky"
select="/test/PocetDluznychSplatekSplatky/val[not(../val > .)][1]" />
<xsl:variable name="PocetDluznychSplatekKarty"
select="/test/PocetDluznychSplatekKarty/val[not(../val > .)][1]" />
<xsl:template match="/">
<xsl:choose>
<xsl:when
test="$PocetDluznychSplatekSplatky >=
$PocetDluznychSplatekKarty">
<xsl:value-of select="$PocetDluznychSplatekSplatky" />
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$PocetDluznychSplatekKarty" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Sample source document:
<test>
<PocetDluznychSplatekSplatky>
<val>22</val>
<val>3241</val>
<val>13</val>
</PocetDluznychSplatekSplatky>
<PocetDluznychSplatekKarty>
<val>1</val>
<val>3234341</val>
<val>13</val>
</PocetDluznychSplatekKarty>
</test>
Output:
3234341
The XPath in each variable's select looks like this:
/test/PocetDluznychSplatekSplatky/val[not(../val > .)][1]
Or, select the val element having no val siblings with a greater value (i.e. the max).
(Obviously, you'll need to adjust the XPath to fit your source document.)
Note: The sort solution performs much better (assuming an n*log(n) sort implementation). The second approach needs to compare each val to every one of its siblings and is therefore quadratic.
I have the following XML source structure:
<turnovers>
<turnover repid="1" amount="500" rate="0.1"/>
<turnover repid="5" amount="600" rate="0.5"/>
<turnover repid="4" amount="400" rate="0.2"/>
<turnover repid="1" amount="700" rate="0.05"/>
<turnover repid="2" amount="100" rate="0.15"/>
<turnover repid="1" amount="900" rate="0.25"/>
<turnover repid="2" amount="1000" rate="0.18"/>
<turnover repid="5" amount="200" rate="0.55"/>
<turnover repid="9" amount="700" rate="0.40"/>
</turnovers>
I need an XSL:value-of select statement that will return the sum of the product of the rate attribute and the amount attribute for a given rep ID. So for rep 5 I need ((600 x 0.5) + (200 x 0.55)).
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:template match="/turnovers">
<val>
<!-- call the sum function (with the relevant nodes) -->
<xsl:call-template name="sum">
<xsl:with-param name="nodes" select="turnover[#repid='5']" />
</xsl:call-template>
</val>
</xsl:template>
<xsl:template name="sum">
<xsl:param name="nodes" />
<xsl:param name="sum" select="0" />
<xsl:variable name="curr" select="$nodes[1]" />
<!-- if we have a node, calculate & recurse -->
<xsl:if test="$curr">
<xsl:variable name="runningsum" select="
$sum + $curr/#amount * $curr/#rate
" />
<xsl:call-template name="sum">
<xsl:with-param name="nodes" select="$nodes[position() > 1]" />
<xsl:with-param name="sum" select="$runningsum" />
</xsl:call-template>
</xsl:if>
<!-- if we don't have a node (last recursive step), return sum -->
<xsl:if test="not($curr)">
<xsl:value-of select="$sum" />
</xsl:if>
</xsl:template>
</xsl:stylesheet>
Gives:
<val>410</val>
The two <xsl:if>s can be replaced by a single <xsl:choose>. This would mean one less check during the recursion, but it also means two additional lines of code.
In plain XSLT 1.0 you need a recursive template for this, for example:
<xsl:template match="turnovers">
<xsl:variable name="selectedId" select="5" />
<xsl:call-template name="sum_turnover">
<xsl:with-param name="turnovers" select="turnover[#repid=$selectedId]" />
</xsl:call-template>
</xsl:template>
<xsl:template name="sum_turnover">
<xsl:param name="total" select="0" />
<xsl:param name="turnovers" />
<xsl:variable name="head" select="$turnovers[1]" />
<xsl:variable name="tail" select="$turnovers[position()>1]" />
<xsl:variable name="calc" select="$head/#amount * $head/#rate" />
<xsl:choose>
<xsl:when test="not($tail)">
<xsl:value-of select="$total + $calc" />
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="sum_turnover">
<xsl:with-param name="total" select="$total + $calc" />
<xsl:with-param name="turnovers" select="$tail" />
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
This should do the trick, you'll need to do some further work to select the distinct repid's
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:variable name="totals">
<product>
<xsl:for-each select="turnovers/turnover">
<repid repid="{#repid}">
<value><xsl:value-of select="#amount * #rate"/></value>
</repid>
</xsl:for-each>
</product>
</xsl:variable>
<totals>
<total repid="5" value="{sum($totals/product/repid[#repid='5']/value)}"/>
</totals>
</xsl:template>
</xsl:stylesheet>
In XSLT 1.0 the use of FXSL makes such problems easy to solve:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:f="http://fxsl.sf.net/"
xmlns:ext="http://exslt.org/common"
exclude-result-prefixes="xsl f ext"
>
<xsl:import href="zipWith.xsl"/>
<xsl:output method="text"/>
<xsl:variable name="vMultFun" select="document('')/*/f:mult-func[1]"/>
<xsl:template match="/">
<xsl:call-template name="profitForId"/>
</xsl:template>
<xsl:template name="profitForId">
<xsl:param name="pId" select="1"/>
<xsl:variable name="vrtfProducts">
<xsl:call-template name="zipWith">
<xsl:with-param name="pFun" select="$vMultFun"/>
<xsl:with-param name="pList1" select="/*/*[#repid = $pId]/#amount"/>
<xsl:with-param name="pList2" select="/*/*[#repid = $pId]/#rate"/>
</xsl:call-template>
</xsl:variable>
<xsl:value-of select="sum(ext:node-set($vrtfProducts)/*)"/>
</xsl:template>
<f:mult-func/>
<xsl:template match="f:mult-func" mode="f:FXSL">
<xsl:param name="pArg1"/>
<xsl:param name="pArg2"/>
<xsl:value-of select="$pArg1 * $pArg2"/>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on the originally posted source XML document, the correct result is produced:
310
In XSLT 2.0 the same solution using FXSL 2.0 can be expressed by an XPath one-liner:
sum(f:zipWith(f:multiply(),
/*/*[xs:decimal(#repid) eq 1]/#amount/xs:decimal(.),
/*/*[xs:decimal(#repid) eq 1]/#rate/xs:decimal(.)
)
)
The whole transformation:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:f="http://fxsl.sf.net/"
exclude-result-prefixes="f xs"
>
<xsl:import href="../f/func-zipWithDVC.xsl"/>
<xsl:import href="../f/func-Operators.xsl"/>
<!-- To be applied on testFunc-zipWith4.xml -->
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:value-of select=
"sum(f:zipWith(f:multiply(),
/*/*[xs:decimal(#repid) eq 1]/#amount/xs:decimal(.),
/*/*[xs:decimal(#repid) eq 1]/#rate/xs:decimal(.)
)
)
"/>
</xsl:template>
</xsl:stylesheet>
Again, this transformation produces the correct answer:
310
Note the following:
The f:zipWith() function takes as arguments a function fun() (of two arguments) and two lists of items having the same length. It produces a new list of the same length, whose items are the result of the pair-wise application of fun() on the corresponding k-th items of the two lists.
f:zipWith() as in the expression takes the function f:multiply() and two sequences of corresponding "ammount" and "rate" attributes. The sesult is a sequence, each item of which is the product of the corresponding "ammount" and "rate".
Finally, the sum of this sequence is produced.
There is no need to write an explicit recursion and it is also guaranteed that the behind-the scenes recursion used within f:zipWith() is never going to crash (for all practical cases) with "stack overflow"
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs"
version="2.0">
<xsl:variable name="repid" select="5" />
<xsl:template match="/">
<xsl:value-of select=
"sum(for $x in /turnovers/turnover[#repid=$repid] return $x/#amount * $x/#rate)"/>
</xsl:template>
</xsl:stylesheet>
You can do this if you just need the value and not xml.
The easiest way to do it in XSLT is probably to use programming language bindings, so that you can define your own XPath functions.
