I am using xslt2.0 for convert one xml format to another xml format. This is my sample xml document.
<w:document>
<w:body>
<w:p>Para1</w:p>
<w:p>Para2</w:p>
<w:p>Para3</w:p>
<w:p>Para4</w:p>
</w:body>
</w:document>
Initially this is my xml format.so, i handled each and every <w:p> elements through my function in xslt given below...
<xsl:template match="document">
<Document>
<xsl:sequence select="mf:group(body/p, 1,count(//w:body//w:p)-1)"/>
</Document>
</xsl:template>
So,In that xslt function, i have coded how to reformat those elements.It's working fine...
But now,Xml format is restructured like given below...
<w:document>
<w:body>
<w:tbl><!--some text with children elements--></w:tbl>
<w:tbl><!--some text with children elements--></w:tbl>
<w:p>Para1</w:p>
<w:p>Para2</w:p>
<w:p>Para3</w:p>
<w:p>Para4</w:p>
</w:body>
</w:document>
So, As of now i have to handle both and elements in a same sequence.....
What i want to do is,
If i encounter elemtents then i have to call my template given below...
<xsl:template match="document">
<Document>
<xsl:for-each select="w:tbl">
<xsl:apply-templates select="w:tbl">
</xsl:apply-templates>
</xsl:for-each>
<xsl:sequence select="mf:group(body/p, 1,count(//w:body//w:p)-1)"/>
</Document>
</xsl:template>
<xsl:template match="w:tbl">
<!--xslt code here -->
</xsl:template>
But the for-each statement is not executed when I trying transformation...
So, Please guide me to get out of this issue...
I think instead of
<xsl:template match="document">
<Document>
<xsl:for-each select="w:tbl">
<xsl:apply-templates select="w:tbl">
</xsl:apply-templates>
</xsl:for-each>
<xsl:sequence select="mf:group(body/p, 1,count(//w:body//w:p)-1)"/>
</Document>
</xsl:template>
you simply want
<xsl:template match="document">
<Document>
<xsl:apply-templates select="w:body/w:tbl"/>
<xsl:sequence select="mf:group(body/p, 1,count(//w:body//w:p)-1)"/>
</Document>
</xsl:template>
If that does not do what you want then please show the result you want.

Given this XML
<dmodule>
<content>
<warningsAndCautionsRef>
<warningRef id="w001" warningIdentNumber="warning-001">
</warningRef>
<warningRef id="w002" warningIdentNumber="warning-002">
</warningRef>
<cautionRef id="c001" cautionIdentNumber="caution-001">
</cautionRef>
<cautionRef id="c002" cautionIdentNumber="caution-002">
</cautionRef>
</warningsAndCautionsRef>
<faultReporting>
<preliminaryRqmts>
<reqSafety>
<safetyRqmts cautionRefs="c001 c002" warningRefs="w001 w002"/>
</reqSafety>
</preliminaryRqmts>
</faultReporting>
</content>
</dmodule>
I would like to tokenize the attributes #cautionRefs (and #warningRefs) and then find the cautionRef element that matches its #id to the tokenized value:
<xsl:template match="#cautionRefs">
<xsl:for-each select="tokenize(.,'\s')">
<xsl:apply-templates select="//*[#id=.]"/>
</xsl:for-each>
</xsl:template>
but the apply-templates fails: Fatal error during transformation Leading '/' selects nothing: the context item is not a node. It works if I don't tokenize and use string functions instead but that is not desirable.
Desired result:
Tokenize #cautionRefs="c001 c002" (which has multiple parent elements)
So each value is passed to the <cautionRef>template that will retrieve the caution and warning statements, to be displayed in a PDF:
<xsl:apply-templates select="//*[#id='c001']"/>
<xsl:apply-templates select="//*[#id='c002']"/>
I tried using <xsl:key name="id" match="*" use="#id"/> with
<xsl:for-each select="key('id',tokenize(.,'\s'))">
but the for-each is blank.
The above apply-templates will match with this <cautionRef> template, which retrieves the caution and warning statements correctly. I just need help with the context of the #cautionRefs template:
<xsl:template match="cautionRef">
<xsl:variable name="IdentNumber" select="#cautionIdentNumber"/>
<xsl:apply-templates select="//cautionSpec[cautionIdent/#cautionIdentNumber=$IdentNumber]"/>
</xsl:template>
You could use a variable and use that for context:
<xsl:template match="#cautionRefs|#warningRefs">
<xsl:variable name="ctx" select="/"/>
<xsl:for-each select="tokenize(.,'\s')">
<xsl:apply-templates select="$ctx//*[#id=.]"/>
</xsl:for-each>
</xsl:template>
but I would use a key like you hinted at (updated to include context based on comments)...
<xsl:key name="by_id" match="*[#id]" use="#id"/>
<xsl:variable name="root" select="/"/>
<xsl:template match="#cautionRefs|#warningRefs">
<xsl:for-each select="tokenize(.,'\s')">
<xsl:apply-templates select="key('by_id',.,$root)"/>
</xsl:for-each>
</xsl:template>
Here's a full working example. NB it's best to have this level of detail in the actual question; i.e. a sample input file, the XSLT, and output, along with an example of what you want the output to look like.
Input:
<test>
<safetyRqmts cautionRefs="c001 c002" warningRefs="w001"/>
<cautionRef id="c001" cautionIdentNumber="caution-001"/>
<cautionRef id="c002" cautionIdentNumber="caution-001"/>
</test>
Stylesheet:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
<xsl:template match="*|#*">
<xsl:copy>
<xsl:apply-templates select="#*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:key name="by_id" match="*[#id]" use="#id"/>
<xsl:template match="#cautionRefs|#warningRefs">
<xsl:apply-templates select="key('by_id', tokenize(.))"/>
</xsl:template>
</xsl:stylesheet>
Output:
<test>
<safetyRqmts><cautionRef id="c001" cautionIdentNumber="caution-001"/><cautionRef id="c002" cautionIdentNumber="caution-001"/></safetyRqmts>
<cautionRef id="c001" cautionIdentNumber="caution-001"/>
<cautionRef id="c002" cautionIdentNumber="caution-001"/>
</test>
I use a tool where a xslt template is pre-defined and it is not desirable to remove it.
<xsl:template match="/">
<Msg xmlns="urn:com.sap.b1i.vplatform:entity">
<xsl:copy-of select="/vpf:Msg/#*"></xsl:copy-of>
<xsl:copy-of select="/vpf:Msg/vpf:Header"></xsl:copy-of>
<Body>
<xsl:copy-of select="/vpf:Msg/vpf:Body/*"></xsl:copy-of>
<Payload Role="X" id="{$atom}">
<xsl:call-template name="transform"></xsl:call-template>
</Payload>
</Body>
</Msg>
<xsl:template name="transform">
<!-- In this area we write our xpath and build the xml-file-->
</xsl:template>
Now I want to use the Muenchian grouping method. But for this method you also need to define a template en key. Like this:
<xsl:key name="KeyOrder" match="/vpf:Msg/vpf:Body/vpf:Payload[#id='atom8']/Orders/jdbc:Row" use="jdbc:RecId2" />
<xsl:template match="Orders" >
<Documents>
<xsl:for-each select="jdbc:Row[count(. | key('KeyOrder', jdbc:RecId2)[1]) = 1]">
<xsl:sort select="jdbc:RecId2" />
<Document>
<xsl:copy-of select="jdbc:RecId2" />
<xsl:for-each select="key('KeyOrder', jdbc:RecId2)">
<xsl:sort select="jdbc:OrderNrRef" />
<xsl:copy-of select="." />
</xsl:for-each>
</Document>
</xsl:for-each>
</Documents>
</xsl:template>
The problem is that the 2 templates won't work togetheter the way I copied it here. That means, I don't get the Muenchian grouping results. It's only works when I 'disable' xsl:template match="/", but then I lose a lot of other information which is necessary further in the process.
So how can I get in my XML file the results of both templates?
I have an example document that looks like this
<document>
<memo>
<to>Allen</to>
<p>Hello! My name is <bold>Josh</bold></p>
<p>It's nice to meet you <bold>Allen</bold>. I hope that we get to meet up more often.</p>
<from>Josh</from>
<memo>
</document>
and this is my XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:company="http://my.company">
<xsl:output method="html"/>
<xsl:variable name="link" select="company:generate-link()"/>
<xsl:template match="/document/memo">
<h1>To: <xsl:value-of select="to"/></h1>
<xsl:for-each select="p">
<p><xsl:apply-templates select="node()" mode="paragraph"/></p>
</xsl:for-each>
<xsl:if test="from">
<p>From: <strong><xsl:value-of select="from"/></strong></p>
</xsl:if>
<xsl:copy-of select="$link"/>
</xsl:template>
<xsl:template match="bold" mode="paragraph">
<b><xsl:value-of select="."/></b>
</xsl:template>
<xsl:template match="text()" mode="paragraph">
<xsl:value-of select="."/>
</xsl:template>
</xsl:stylesheet>
and the variable link contains the following example node:
When I do a copy-of out the variable link it prints out the node correctly (but obviously without any text). I want to insert it into the document and replace the text using XSLT. For example, the text could be:
View all of <xsl:value-of select="/document/memo/from"/>'s documents.
So the resulting document would look like:
<h1>To: Allen</h1>
<p>Hello! My name is <b>Josh</b></p>
<p>It's nice to meet you <b>Allen</b>. I hope that we get to meet up more often.</p>
<from>Josh</from>
View all of Josh's documents.
I have been searching the internet on how to do this but I couldn't find anything. If anyone could help I would appreciate it a lot!
Thanks,
David.
You haven't said which XSLT processor that is nor have you shown the code of that extension function to allow us to understand what it returns but based on your comment saying it returns a node you can usually process it further with templates so if you use <xsl:apply-templates select="$link"/> and then write a template
<xsl:template match="a[#href]">
<xsl:copy>
<xsl:copy-of select="#*"/>
View all of <xsl:value-of select="$main-doc/document/memo/from"/>'s documents.
</xsl:copy>
</xsl:template>
where you declare a global variable <xsl:variable name="main-doc" select="/"/> you should be able to transform the node returned from your function.
Im struggling a bit with the following. Given that items may contain several part and spec pairs, i want to process each pair, or apply the template to the item more than once.
Currently, each item is processed once and I'm missing the second part.
<figure>
<list>
<item>
<part>
<p>74174</p>
</part>
<spec>
<u>a1</u>
</spec>
<part>
<p>75375</p>
</part>
<spec>
<u>a4</u>
</spec>
</item>
</list>
</figure>
Stylesheet:
<xsl:if test="$a = 'abc'">
<xsl:apply-templates mode="pt" select="/figure/list/item" />
</xsl:if>
<xsl:template mode="pt" match="item[./part]">
<xsl:call-template name="ptt">
<xsl:with-param name="p"><xsl:value-of select="part/p"/>
</xsl:with-param>
<xsl:with-param name="pr">
<xsl:if test="spec/u">
<xsl:element name="pr">
<xsl:element name="rpn">
<xsl:value-of select="spec/u"/>
</xsl:element>
<xsl:element name="rtn">Alt</xsl:element>
</xsl:element>
</xsl:if>
</xsl:with-param>
</xsl:call-template>
</xsl:template>
I simplified and cropped the code a bit since it goes on and on and on..
Edit: This next one is generating my new elements based solely on the input params
<xsl:template name="ptt">
<xsl:param name="p"/>
<xsl:param name=u"/>
</xsl:template>
It seems that you are unwilling to show a self-contained and complete example (for your future questions, do not make it quite so hard for people to help you), so I am not sure whether the following is helpful to you.
Assuming the XML input you have shown, the stylesheet below demonstrates a way to call a named template for each pair of spec and part elements, as you requested.
It uses xsl:for-each-group (which is exclusive to XSLT 2.0, but you did not tell which version of XSLT you use) to define groups that start with a part element, resulting in the said pairs. Then, for each group, the named template ptt is invoked with p and u as parameters.
Stylesheet
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:strip-space elements="*"/>
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="item">
<xsl:for-each-group select="*" group-starting-with="part">
<xsl:call-template name="ptt">
<xsl:with-param name="p" select="current-group()[1]/p"/>
<xsl:with-param name="u" select="current-group()[2]/u"/>
</xsl:call-template>
</xsl:for-each-group>
</xsl:template>
<xsl:template name="ptt">
<xsl:param name="p"/>
<xsl:param name="u"/>
<result>
<part><xsl:value-of select="$p"/></part>
<spec><xsl:value-of select="$u"/></spec>
</result>
</xsl:template>
</xsl:transform>
XML Output
<?xml version="1.0" encoding="UTF-8"?>
<result>
<part>74174</part>
<spec>a1</spec>
</result>
<result>
<part>75375</part>
<spec>a4</spec>
</result>
Well with call-template and a parameter <xsl:with-param name="p"><xsl:value-of select="part/p"/></xsl:with-param> you are making it harder than it needs to be, assuming XSLT 1.0 the <xsl:with-param name="p"><xsl:value-of select="part/p"/></xsl:with-param> fills the parameter p with a text node of the string value of the first element selected by part/p. So at least use simply <xsl:with-param name="p-elements" select="part/p"/>, then the parameter value is a node-set with all p elements.
Better yet, simply use template matching and apply-templates consistently, then you don't have to struggle with call-template and with-param.
Based on your comments you could just use
<xsl:template mode="pt" match="item[part]">
<xsl:apply-templates select="part" mode="pt"/>
</xsl:template>
<xsl:template match="part" mode="pt">
<xsl:variable name="spec" select="following-sibling::*[1][self::spec]"/>
...
</xsl:template>
I'm working with an xml that I need to copy and update to pass on for further processing. The issue I'm having is that I have not figured out an efficient method to do this. Essentially, I want to update some data, conditionally, then copy all the nodes that were not updated. Why this is challenging is due to the volume and variance in the number and name of nodes to be copied. I also want to NOT copy nodes that have no text value. Here is an example:
INPUT XML
<root>
<PersonProfile xmlns:'namespace'>
<ID>0001</ID>
<Name>
<FirstName>Jonathan</FirstName>
<PreferredName>John</PreferredName>
<MiddleName>A</MiddleName>
<LastName>Doe</LastName>
</Name>
<Country>US</Country>
<Biirthdate>01-01-1980</Birthdate>
<BirthPlace>
<City>Townsville</City>
<State>OR</State>
<Country>US</Country>
</Birthplace>
<Gender>Male</Gender>
<HomeState>OR</HomeState>
...
<nodeN>text</nodeN>
</PersonProfile>
</root>
The "PersonProfile" node is just one of several node sets within the "root" element, each with their own subset of data. Such as mailing address, emergency contact info, etc. What I am attempting to do is update nodes if the variable has a new value for them then copy all the nodes that were not updated.
Here is my current XSLT
<xsl:stylesheet version="2.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<xsl:variable name='updateData' select='document("report")'/>
<!-- Identity Transform -->
<xsl:template match='#* | node()'>
<xsl:if test'. != ""'>
<xsl:copy>
<xsl:apply-templates select='#* | node()'/>
</xsl:copy>
</xsl:if>
</xsl:template>
<!-- Template to update Person Profile -->
<xsl:template match='PersonProfile'>
<xsl:copy>
<xsl:apply-templates select='*'/>
<xsl:element name='Name'>
<xsl:if test='exists($updateData/Preferred)'>
<xsl:element name='FirstName'>
<xsl:value-of select='$reportData/FirstName'/>
</xsl:element>
</xsl:if>
<xsl:if test='exists($updateData/Preferred)'>
<xsl:element name='PreferredName'>
<xsl:value-of select='$updateData/Preferred'/>
</xsl:element>
</xsl:if>
<xsl:if test='exists($updateData/Middle)'>
<xsl:element name='MiddleName'>
<xsl:value-of select='$updateData/Middle'/>
</xsl:element>
</xsl:if>
<xsl:if test='exists($updateData/LastName)'>
<xsl:element name='LastName'>
<xsl:value-of select='$updateData/wd:LastName'/>
</xsl:element>
</xsl:if>
</xsl:element>
<xsl:if test='exists($updateData/Country)'>
<xsl:element name='Country'>
<xsl:value-of select='$updateData/Country'/>
</xsl:element>
</xsl:if>
....
<!-- follows same structure until end of template -->
</xsl:copy>
</xsl:template>
<!-- More Templates to Update other Node sets -->
</xsl:stylesheet>
What's happening right now, is that it's copying ALL the nodes and then adding the updates values. Using Saxon-PE 9.3.0.5, I'll get an output similar to this:
Sample Output
<root>
<PersonProfile xmlns:'namespace'>
<ID>0001</ID>
<Name>
<FirstName>Jonathan</FirstName>
<PreferredName>John</PreferredName>
<MiddleName>A</MiddleName>
<LastName>Doe</LastName>
</Name>
<Country>US</Country>
<Biirthdate>01-01-1980</Birthdate>
<BirthPlace>
<City>Townsville</City>
<State>OR</State>
<Country>US</Country>
</Birthplace>
<Gender>Male</Gender>
<HomeState>OR</HomeState>
...
<nodeN>text</nodeN>
<PreferredName>Jonathan</PreferredName>
<HomeState>WA</HomeState>
</PersonProfile>
</root>
I realize this is happening because I am applying the templates to all the nodes in PersonProfile and that I could specify which nodes to exclude, but I feel like this is a very poor solution as the volume of nodes could be upwards of 30 or more and that would require a written value for each one. I trust XML has a more elegant solution than to explicitly list each of these nodes. I would like to have an out like this:
Desired Output
<root>
<PersonProfile xmlns:'namespace'>
<ID>0001</ID>
<Name>
<FirstName>Jonathan</FirstName>
<PreferredName>Jonathan</PreferredName>
<MiddleName>A</MiddleName>
<LastName>Doe</LastName>
</Name>
<Country>US</Country>
<Biirthdate>01-01-1980</Birthdate>
<BirthPlace>
<City>Townsville</City>
<State>OR</State>
<Country>US</Country>
</Birthplace>
<Gender>Male</Gender>
<HomeState>WA</HomeState>
...
<nodeN>text</nodeN>
</PersonProfile>
</root>
If anyone could help me create a template structure that would work for the xml structure, I would GREATLY appreciate it. It would need to be "reusable" as there are similar node structures like Person Profile I would have to apply it to, but with different node names and number of elements, etc.
Thanks in advance for any help!

This should work for your original question:
<xsl:stylesheet version="2.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<xsl:variable name='updateData' select='document("report")'/>
<!-- Identity Transform -->
<xsl:template match='#* | node()' name='copy'>
<xsl:copy>
<xsl:apply-templates select='#* | node()'/>
</xsl:copy>
</xsl:template>
<xsl:template match='*[not(*)]'>
<xsl:variable name='matchingValue'
select='$updateData/*[name() = name(current())]'/>
<xsl:choose>
<xsl:when test='$matchingValue'>
<xsl:copy>
<xsl:apply-templates select='#*' />
<xsl:value-of select='$matchingValue'/>
</xsl:copy>
</xsl:when>
<xsl:when test='normalize-space()'>
<xsl:call-template name='copy' />
</xsl:when>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
As far as inserting new elements that are not present in the source XML, that's trickier. Could you open a separate question for that? I may have some ideas for how to approach that.
