<xsl:variable name="Rows" select=" .. some stmt .." />
<xsl:for-each select="$Rows">
<xsl:value-of select="#ATTRNAME"/>
</xsl:for-each>
Would like to know how to find 'Rows' with unique/distinct attribute 'ATTRNAME' [ in XSLT 1.0 ].
Grouping in XSLT 1.0 is done using xsl:key. The following prints only the unique elements of the root element:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" omit-xml-declaration="yes"/>
<xsl:key name="attrByVal" match="/*/#*" use="."/>
<xsl:template match="/">
<xsl:apply-templates select="/*/#*"/>
</xsl:template>
<xsl:template match="#*[generate-id()=generate-id(key('attrByVal', .)[1])]">
<xsl:value-of select="concat(name(), ': ', ., '
')"/>
</xsl:template>
<xsl:template match="#*"/>
</xsl:stylesheet>
Explanation: First, we group all attributes of the root element by value:
<xsl:key name="attrByVal" match="/*/#*" use="."/>
Then, create a template that matches only the first element for each key in the group:
<xsl:template match="#*[generate-id()=generate-id(key('attrByVal', .)[1])]">
And ignore all the others:
<xsl:template match="#*"/>
Example input:
<root one="apple" two="apple" three="orange" four="apple"/>
Output:
one: apple
three: orange
XSLT 2.0 solution :
<xsl:for-each-group select="$Rows" group-by="#ATTRNAME">
<!-- Do something with the rows in the group. These rows
can be accessed by the current-group() function. -->
</xsl:for-each-group>

I would like to add a node based on , but the problem is the categories are in a separate file and moreover I would like to loop to find all based on .
Let me show an example:
category.xml:
<ROOT>
<GROUPITEM>
<G_ID>1368</G_ID>
<GROUP>Phone</GROUP>
<PARENT>0</PARENT>
</GROUPITEM>
<GROUPITEM>
<G_ID>1194</G_ID>
<GROUP>Apple</GROUP>
<PARENT>1368</PARENT>
</GROUPITEM>
<GROUPITEM>
<G_ID>1195</G_ID>
<GROUP>2019</GROUP>
<PARENT>1194</PARENT>
</GROUPITEM>
</ROOT>
item.xml:
<ROOT>
<SHOPITEM>
<PRODUCT_ID>96555</PRODUCT_ID>
<GROUP_ID>1195</GROUP_ID>
<PRODUCT_NAME>Apple iPhone 8 Plus</PRODUCT_NAME>
</SHOPITEM>
</ROOT>
Example output:
<ROOT>
<SHOPITEM>
<PRODUCT_ID>96555</PRODUCT_ID>
<GROUP_ID>1195</GROUP_ID>
<PRODUCT_NAME>Apple iPhone 8 Plus</PRODUCT_NAME>
<CATEGORY>Phone | Apple | 2019</CATEGORY>
</SHOPITEM>
</ROOT>
In simple words I am looking for a way to create node (in item.xml) and add here value ( from category.xml) based on (item.xml): search in category.xml for the same -> if found, add it -> search more based on (if success add separator + value) -> loop.
Try something like (untested):
XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:key name="group" match="GROUPITEM" use="G_ID" />
<xsl:template match="SHOPITEM">
<xsl:copy>
<xsl:copy-of select="*"/>
<CATEGORY>
<xsl:apply-templates select="key('group', GROUP_ID, document('category.xml'))"/>
</CATEGORY>
</xsl:copy>
</xsl:template>
<xsl:template match="GROUPITEM">
<xsl:variable name="parent" select="key('group', PARENT)" />
<xsl:if test="$parent">
<xsl:apply-templates select="$parent"/>
<xsl:text> | </xsl:text>
</xsl:if>
<xsl:value-of select="GROUP"/>
</xsl:template>
</xsl:stylesheet>
Is it possible to sort nodes as follows:
Example XML
<record>
<id>0</id>
<sku>0</sku>
<name>Title</name>
<prop>456</prop>
<number>99</number>
</record>
If I apply this template
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="record/*">
<xsl:param select="." name="value"/>
<div>
<xsl:value-of select="concat(local-name(), ' - ', $value)"/>
</div>
</xsl:template>
</xsl:stylesheet>
Ouput:
<div>id - 0</div>
<div>sku - 0</div>
<div>name - Title</div>
<div>prop - 456</div>
<div>number - 99</div>
However, I would like all 0 values to be outputted last, as so:
<div>name - Title</div>
<div>prop - 456</div>
<div>number - 99</div>
<div>id - 0</div>
<div>sku - 0</div>
Is this possible by applying a sort to the <xsl:apply-templates/>?
There is an easy way of achieving this with XSLT-1.0. Just use a predicate on xsl:apply-templates checking if the content is zero:
<xsl:template match="record/*">
<div>
<xsl:value-of select="concat(local-name(), ' - ', .)"/>
</div>
</xsl:template>
<xsl:template match="/record">
<xsl:apply-templates select="*[normalize-space(.) != '0']" />
<xsl:apply-templates select="*[normalize-space(.) = '0']" />
</xsl:template>
This does not sort the output, but groups it the way you want it. The xsl:param is unnecessary.
As far as I see your question, the issue is not any sort at all.
You even didn't write what is the specific value, which you mentioned
it the title. It is rather an arbitrary sequence of child elements of record.
Try the following script, performing just that:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" encoding="UTF-8" indent="yes" />
<xsl:template match="record">
<xsl:copy>
<xsl:apply-templates select="name, prop, number, id, sku"/>
</xsl:copy>
</xsl:template>
<xsl:template match="record/*">
<div><xsl:value-of select="concat(local-name(), ' - ', .)"/></div>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy><xsl:apply-templates select="#*|node()"/></xsl:copy>
</xsl:template>
</xsl:transform>
I used XSLT 2.0, because initially you did't specify the XSLT version.
Could you move on to version 2.0? As you can see, it allows to write quite
an elegent solution (impossible in version 1.0).
I also changed your template matching record/*. You actually don't
need any param. It is enough to use . - the value of the current
element.
Edit
Another possibility is that you want the following sort:
First, elements with non-numeric value (in your case, only name),
maybe without any sort.
Then elements with numeric value, sorted descending on this value.
If this is the case, then change the template matching record to the
following:
<xsl:template match="record">
<xsl:copy>
<xsl:apply-templates select="*[not(. castable as xs:integer)]"/>
<xsl:apply-templates select="*[. castable as xs:integer]">
<xsl:sort select="." order="descending" data-type="number"/>
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
And add:
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="#all"
to transform tag.
But I still can't see anything, which can be called the specific value.
I am trying to conditional check on the input xml file and place the value.
input xml:
<workorder>
<newwo>1</newwo>
</workorder>
If newwo is 1, then I have to set in my output as "NEW" else "OLD"
Expected output is:
newwo: "NEW"
my xslt is:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0">
<xsl:template match="/">
<xsl:apply-templates select="NEWWO" />
</xsl:template>
<xsl:template match="/NEWWO">
<xsl:text>{
newwo:"
</xsl:text>
<xsl:choose>
<xsl:when test="NEWWO != '0'">NEW</xsl:when>
<xsl:otherwise>OLD</xsl:otherwise>
</xsl:choose>
<xsl:text>"
}</xsl:text>
</xsl:template>
Please help me. Thanks in advance!
I see a number of reasons you aren't getting output.
The xpaths are case sensitive. NEWWO is not going to match newwo.
You match / and then apply-templates to newwo (case fixed), but newwo doesn't exist at that context. You'll either have to add */ or workorder/ to the apply-templates (like select="*/newwo") or change / to /* or /workorder in the match.
You match /newwo (case fixed again), but newwo is not the root element. Remove the /.
You do the following test: test="newwo != '0'", but newwo is already the current context. Use . or normalize-space() instead. (If you use normalize-space(), be sure to test against a string. (Quote the 1.))
Here's an updated example.
XML Input
<workorder>
<newwo>1</newwo>
</workorder>
XSLT 1.0
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text"/>
<xsl:template match="/*">
<xsl:apply-templates select="newwo" />
</xsl:template>
<xsl:template match="newwo">
<xsl:text>{
newwo: "</xsl:text>
<xsl:choose>
<xsl:when test=".=1">NEW</xsl:when>
<xsl:otherwise>OLD</xsl:otherwise>
</xsl:choose>
<xsl:text>"
}</xsl:text>
</xsl:template>
</xsl:stylesheet>
Output
{
newwo: "NEW"
}
You try it as below
<?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" version="1.0">
<xsl:template match="/">
<xsl:choose>
<xsl:when test="/workorder/newwo = 1">
<xsl:text disable-output-escaping="no"> newwo:New</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text disable-output-escaping="no"> newwo:Old</xsl:text> </xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
I have the below xml text,
<SUBSCRIBER>
<Anumber>639081000000</Anumber>
<FirstCallDate>20130430104419</FirstCallDate>
<SetyCode>TNT</SetyCode>
<Status>ACT</Status>
<RoamIndicator/>
<PreloadCode>P1</PreloadCode>
<CreationDate>20130116100037</CreationDate>
<PreActiveEndDate/>
<ActiveEndDate>20130804210541</ActiveEndDate>
<GraceEndDate>20140502210541</GraceEndDate>
<RetailerIndicator/>
<OnPeakAccountID>9100</OnPeakAccountID>
<OnPeakSmsExpDate>20130804210504</OnPeakSmsExpDate>
<UnivWalletAcc/>
<UnliSmsOnCtl>20130606211359</UnliSmsOnCtl>
<UnliSmsTriCtl/>
<UnliSmsGblCtl/>
<UnliMocOnCtl>20130606211359</UnliMocOnCtl>
<UnliMocTriCtl/>
<UnliMocGblCtl/>
<UnliSurfFbcCtl>20130606212353</UnliSurfFbcCtl>
</SUBSCRIBER>
How can I iterate/parse over each xml tag name and get the value ( I need the name of the tag and value in a different variables) ? And also, How can I start iterating from particular tag name ? Ex: I would like to start iterating UnivWalletAcc
Please advise.
So far, I have tried the following,
<xsl:template match="SUBSCRIBER">
<xsl:variable name="tagName">
<xsl:value-of select="/*/*/name()"/>
</xsl:variable>
<xsl:variable name="tagValue">
<xsl:value-of select="/*/*/text()"/>
</xsl:variable>
<xsl:value-of select="$tagName"/>
<xsl:value-of select="$tagValue"/>
</xsl:template>
As an alternative to Veenstra's solution, instead of the xsl:if in the SUBSCRIBER/* template, you can control the iteration in the apply-templates:
<xsl:template match="SUBSCRIBER">
<data>
<xsl:apply-templates select="UnivWalletAcc,
UnivWalletAcc/following-sibling::*" />
</data>
</xsl:template>
With the following XSLT you can loop through all childs of the node SUBSCRIBER:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<!-- Identity template that will loop over all nodes and attributes -->
<xsl:template match="#*|node()">
<xsl:apply-templates select="#*|node()" />
</xsl:template>
<!-- Template to match the root and create new root -->
<xsl:template match="SUBSCRIBER">
<data>
<xsl:apply-templates select="#*|node()" />
</data>
</xsl:template>
<!-- Template to loop over all childs of SUBSCRIBER node -->
<xsl:template match="SUBSCRIBER/*">
<!-- This will test if we have seen the UnivWalletAcc node already, if so, output something, otherwise, output nothing -->
<xsl:if test="preceding-sibling::UnivWalletAcc or self::UnivWalletAcc">
<tag>
<tagName><xsl:value-of select="name()" /></tagName>
<tagValue><xsl:value-of select="." /></tagValue>
</tag>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
<choices>
<sic />
<corr />
<reg />
<orig />
</choices>
<choice>
<corr>Red</corr>
<sic>Blue</sic>
<choice>
I want to select the first element in <choice> whose name matches the name of any element in <choices>.
If name(node-set) returned a list of names instead of only the name of the first node, I could use
select="choice/*[name() = name(choices/*)][1]"
But it doesn't (at least not in 1.0), so instead I join the names together in a string and use contains():
<xsl:variable name="choices.str">
<xsl:for-each select="choices/*">
<xsl:text> </xsl:text><xsl:value-of select="concat(name(),' ')"/>
</xsl:for-each>
</xsl:variable>
<xsl:apply-templates select="choice/*[contains($choices.str,name())][1]"/>
and get what I want:
Red, the value of <corr>
Is there a more straightforward way?
I. Use this XPath 2.0 one-liner:
/*/choice/*[name() = /*/choices/*/name()][1]
When this XPath expression is evaluated against the following XML document (the provided one, but corrected to become a well-formed XML document):
<t>
<choices>
<sic />
<corr />
<reg />
<orig />
</choices>
<choice>
<corr>Red</corr>
<sic>Blue</sic>
</choice>
</t>
the correct element is selected:
<corr>Red</corr>
II. XSLT 1.0 (no keys!):
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="vNames">
<xsl:for-each select="/*/choices/*">
<xsl:value-of select="concat(' ', name(), ' ')"/>
</xsl:for-each>
</xsl:variable>
<xsl:template match="/">
<xsl:copy-of select=
"/*/choice/*
[contains($vNames, concat(' ', name(), ' '))]
[1]"/>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied on the same XML document (above), again the correct element is selected (and copied to the output):
<corr>Red</corr>
III. Using keys:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:key name="kChoiceByName" match="choice/*"
use="boolean(/*/choices/*[name()=name(current())])"/>
<xsl:template match="/">
<xsl:copy-of select="/*/choice/*[key('kChoiceByName', true())][1]"/>
</xsl:template>
</xsl:stylesheet>
When this transformation is applied against the same XML document (above), the same correct result is produced:
<corr>Red</corr>
It is recommended to the reader to try to understand how this all "works" :)
You can use the key() function like this...
When this input document...
<t>
<choices>
<sic />
<corr />
<reg />
<orig />
</choices>
<choice>
<corr>Red</corr>
<sic>Blue</sic>
</choice>
</t>
...is supplied as input to this XSLT 1.0 style-sheet...
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:key name="kChoices" match="choices/*" use="name()" />
<xsl:template match="/">
<xsl:variable name="first-choice" select="(*/choice/*[key('kChoices',name())])[1]" />
<xsl:value-of select="$first-choice" />
<xsl:text>, the value of <</xsl:text>
<xsl:value-of select="name( $first-choice)" />
<xsl:text>></xsl:text>
</xsl:template>
</xsl:stylesheet>
...this output text is produced...
Red, the value of <corr>
XSLT 2.0 Aside
In XSLT 2.0, you would be able to use the following alternatives for the computation of the $first-choice variable...
Option 1:
(*/choice/*[for $c in . return ../../choices/*[name()=name($c)]])[1]
Option 2:
(*/choice/*[some $c in ../../choices/* satisfies name($c)=name()])[1]
