Seperate attribute values with comma in xslt 1.0? - xslt

My source XML:-
<wireframe:xaIDExclusion>
<widget:xaID id="12"/>
<widget:xaID id="121"/>
<widget:xaID id="123"/>
<widget:xaID id="124"/>
<widget:xaID id="3456"/>
</wireframe:xaIDExclusion>
This is what i tried
<xsl:template match="widget:xaID">
<xsl:element name="xaid">
<xsl:variable name ="value" select="#id"></xsl:variable>
<xsl:value-of select="concat($value,',')"></xsl:value-of>
</xsl:element>
</xsl:template>
I need output like this,how to do that
12,121,123,124,3456
Thanks in advance

The problem with your approach is that you're matching widget:xaID and then creating a xaid element; this results in multiple xaid elements, one for each widget:xaID. You need to create the xaid element while you are in the context of the parent of widget:xaID.
Try (untested, because you did not provide a well-formed XML):
<xsl:template match="wireframe:xaIDExclusion">
<xaid>
<xsl:for-each select="widget:xaID">
<xsl:value-of select="#id">
<xsl:if test="position()!=last()">, </xsl:if>
</xsl:for-each>
</xaid>
</xsl:template>

Partially rename an XML node

Given the XML snippet:
<rng:define name="starting_limits">
<rng:element name="limits">
<rng:ref name="Limits"/>
</rng:element>
</rng:define>
I want this:
<rng:define name="limits">
<rng:element name="limits">
<rng:ref name="Limits"/>
</rng:element>
</rng:define>
For all define elements. So I just want to remove the "starting_" prefix for all define element name attributes in the infoset.
you can use this:
<xsl:template match="#*[starts-with(., 'starting_')]">
<xsl:attribute name="{name()}" select="replace(., 'starting_', '')"/>
</xsl:template>
it matched all attribute start-with 'starting_' and remove it from output
In your XML the attribute is called name and has a value of starting_xxxx, so to match it, you would do this...
<xsl:template match="#name[starts-with(., 'starting_')]">
Or maybe this, in XSLT 2.0 and above
<xsl:template match="#name[matches(., 'starting_.*')]">
To remove the starting_attribute you can do one of the following, for example
<xsl:value-of select="substring-after(., 'starting_')"/>
<xsl:value-of select="substring(., 10)"/>
So, for example, your template may look like this
<xsl:template match="#name[starts-with(., 'starting_')]">
<xsl:attribute name="name">
<xsl:value-of select="substring(., 10)"/>
</xsl:attribute>
</xsl:template>
If you wanted to make it more generic, and match any attribute, not just one called name, you could change it to this
<xsl:template match="#*[starts-with(., 'starting_')]">
<xsl:attribute name="{name()}">
<xsl:value-of select="substring(., 10)"/>
</xsl:attribute>
</xsl:template>

Split large xslt into smaller ones

I've seen xsl:include tag, but seems like this works for seperate templates.
In my case, its a single parent tag with multiple assignments like this
<xsl:template match="/">
<ns5:taskListResponse>
<xsl:for-each select="/tns:taskListResponse/task:task">
<ns7:task>
<xsl:if test="task:title">
<ns7:title>
<xsl:value-of select="task:title"/>
</ns7:title>
</xsl:if>
<xsl:if test="task:taskDefinitionURI">
<ns7:taskDefinitionURI>
<xsl:value-of select="task:taskDefinitionURI"/>
</ns7:taskDefinitionURI>
</xsl:if>
<xsl:if test="task:creator">
<ns7:creator>
<xsl:value-of select="task:creator"/>
</ns7:creator>
</xsl:if>
........100 more tags like this.....
...................
</xsl:for-each>
</ns5:taskListResponse>
How can I split this xsl?
I want to put some tags in another file and include those inside the
Appreciate your help

I would consider splitting this up into separate templates, for example each of the if tests could be replaced by apply-templates, and the following template to do the work:
<xsl:template match="task:*">
<xsl:element name="ns7:{local-name()}">
<xsl:value-of select="." />
</xsl:element>
</xsl:template>
If you don't need to re-order the children then the entire stylesheet boils down to
<xsl:template match="/">
<ns5:taskListResponse>
<xsl:apply-templates select="/tns:taskListResponse/task:task" />
</ns5:taskListResponse>
</xsl:template>
<xsl:template match="task:task">
<ns7:task><xsl:apply-templates select="*" /></ns7:task>
</xsl:template>
<xsl:template match="task:*">
<xsl:element name="ns7:{local-name()}">
<xsl:value-of select="." />
</xsl:element>
</xsl:template>
It gets slightly more complex if you do need to re-order things, then you'll need 100 separate <xsl:apply-templates select="task:foo" /> in place of the <xsl:apply-templates select="*" />, but it's still smaller and more modular.

Structural requirements when using "except" in XPATH/XSL

I am having trouble when using "except" in xpath. Here is the chunk of problem code. (I tried to simplify as much as possible without obscuring the whole problem).:
<!--First, create a variable containing some nodes that we want to filter out.
(I'm gathering elements that are missing child VALUE elements
and whose child DOMAIN and VARIABLE elements only occur once
in the parent list of elements.)
I've confirmed that this part does generate the nodes I want,
but maybe this is the incorrect result structure?-->
<xsl:variable name="badValues">
<xsl:for-each select="$root/A[not(VALUE)]">
<xsl:choose>
<xsl:when test="count($root/A[DOMAIN=current()/DOMAIN and VARIABLE=current()/VARIABLE])=1">
<xsl:copy-of select="."/>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:variable>
<!--Next Loop over the original nodes, minus those bad nodes.
For some reason, this loops over all nodes and does not filter out the bad nodes.-->
<xsl:for-each select="$root/A except $badValues/A"> ...
When you create an xsl:variable without using #select and do not specify the type with the #as, it will create the variable as a temporary tree.
You want to create a sequence of nodes, so that when they are compared in the except operator, they are "seen" as the same nodes. You can do this by specifying as="node()*" for the xsl:variable and by using xsl:sequence instead of xsl:copy-of:
<xsl:variable name="badValues" as="node()*">
<xsl:for-each select="$root/A[not(VALUE)]">
<xsl:choose>
<xsl:when test="count($root/A[DOMAIN=current()/DOMAIN
and VARIABLE=current()/VARIABLE])=1">
<xsl:sequence select="."/>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:variable>
Alternatively, if you were to use a #select and eliminate the xsl:for-each it would also work. As Martin Honnen suggested, you could use an xsl:key and select the values like this:
<xsl:key name="by-dom-and-var" match="A" use="concat(DOMAIN, '|', VARIABLE)"/>
Then change your badValues to this:
<xsl:variable name="badValues"
select="$root/A[not(VALUE)]
[count(key('by-dom-and-var',
concat(DOMAIN, '|', VARIABLE))/VARIABLE) = 1]"/>>
You can see the difference in the identity of the nodes by using the generate-id() function as you iterate over the items by executing this stylesheet:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:template match="/">
<xsl:variable name="root" select="*" as="item()*"/>
<xsl:variable name="originalBadValues">
<xsl:for-each select="$root/A[not(VALUE)]">
<xsl:choose>
<xsl:when test="count($root/A[DOMAIN=current()/DOMAIN
and VARIABLE=current()/VARIABLE])=1">
<xsl:copy-of select="."/>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:variable>
<xsl:variable name="badValues" as="node()*">
<xsl:for-each select="$root/A[not(VALUE)]">
<xsl:choose>
<xsl:when test="count($root/A[DOMAIN=current()/DOMAIN
and VARIABLE=current()/VARIABLE])=1">
<xsl:sequence select="."/>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</xsl:variable>
<!--These are the generated ID values of all the A elements-->
<rootA>
<xsl:value-of select="$root/A/generate-id()"
separator=", "/>
</rootA>
<!--These are the generated ID values for
the original $badValues/A -->
<originalBadValues>
<xsl:value-of select="$originalBadValues/A/generate-id()"
separator=", " />
</originalBadValues>
<!--These are the generated ID values for
the correct selection of $badValues-->
<badValues>
<xsl:value-of select="$badValues/generate-id()"
separator=", " />
</badValues>
<!--The generated ID values for the result of
the except operator filter-->
<final>
<xsl:value-of select="($root/A except $badValues)/generate-id()"
separator=", "/>
</final>
</xsl:template>
</xsl:stylesheet>
Executed against this XML file:
<doc>
<A>
<VALUE>skip me</VALUE>
<DOMAIN>a</DOMAIN>
<VARIABLE>a</VARIABLE>
</A>
<A>
<DOMAIN>a</DOMAIN>
<VARIABLE>a</VARIABLE>
</A>
<A>
<DOMAIN>b</DOMAIN>
<VARIABLE>b</VARIABLE>

<A>
<DOMAIN>c</DOMAIN>
<VARIABLE>c</VARIABLE>
</A>
<A>
<DOMAIN>a</DOMAIN>
<VARIABLE>a</VARIABLE>
</A>
</doc>
It produces the following output:
<rootA>d1e3, d1e15, d1e24, d1e33, d1e42</rootA>
<originalBadValues>d2e1, d2e9</originalBadValues>
<badValues>d1e24, d1e33</badValues>

Selectively copy and update xml nodes using XSLT

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.

Get conditional value from previous node

I have this XSLT 2.0 template:
<xsl:template match="footnote">
<xsl:variable name = "string" select="./text()"/>
<xsl:variable name = "bool">
<xsl:choose>
<xsl:when test="$string = preceding::footnote/text()">
<xsl:text>false</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>true</xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:if test="$bool = 'true'">
<xsl:variable name="footnoteCount">
<xsl:call-template name="getItemNumber">
<xsl:with-param name="node" select="."/>
</xsl:call-template>
</xsl:variable>
<!-- DO XSL-FO TRANSFORMATION STUFF-->
</xsl:if>
<xsl:if test="$bool = 'false'">
<xsl:variable name = "footnoteCount">
<xsl:if test="$string = preceding::footnote/text()">
<xsl:value-of select="preceding::footnote/$footnoteCount"/>
</xsl:if>
</xsl:variable>
<!--DO XSL-FO TRANSFORMATION STUFF-->
</xsl:if>
</xsl:template>
Edited sample XML. I'd like to transform this:
<footnote>Foo bar</footnote>
<footnote>Bar foo</footnote>
<footnote>Foo bar</footnote>
<footnote>Foo bar</footnote>
<footnote>Bar</footnote>
<footnote>Foo</footnote>
Into this:
<footnote>Foo bar</footnote>
<footnote>Bar foo</footnote>
<footnote>Bar</footnote>
<footnote>Foo</footnote
And then stylise it using XSL-FO. The aim of this styling is that text in the main body will have a numbered reference, which is represented by $footnotecount, to the footnote which is then rendered at the bottom of the page. I need to transform the document so that duplicate footnates are only rendered once and that the number reference ($footnoteCount) is the same for each duplicate.
So what I'm trying to do with this template is:
Determine whether a footnote element with the current node's text already exists.
If it doesn't exist (i.e, '$bool' is 'true') , find the previous footnote's number, increment it (this is done in the 'getItemNumber' template) and create a 'new' footnote. If it does exist ($bool is 'false'), get the $footnoteCount variable of the node that the text matches and use it for the current node.
It's the scenario in which the footnote already exists that I'm having trouble with. I have no idea how to get the $footnoteCount variable from a previous, specific node dependent on whether than node meets a certain criteria (whether its text is the same as the $string variable in the current node). It's being made more difficult by the fact that the $footnoteCount variable only exists conditionally (even if in practice it will always exist since $bool has to be either true or false).
Does anyone have advice on what to do here?
This looks like a grouping problem, and in XSLT2.0 you can make use of the xsl:for-each-group element to get the distinct elements
<xsl:for-each-group select="footnote" group-by=".">
I think you need a different approach to do your numbering. Firstly you could create a variable to hold a 'look-up' of footnote descriptions and their index
<xsl:variable name="footnotes">
<xsl:for-each-group select="//footnote" group-by=".">
<footnote id="{position()}">
<xsl:value-of select="."/>
</footnote>
</xsl:for-each-group>
</xsl:variable>
This means the footnotes variable contains the following elements
<footnote id="1">Foo bar</footnote>
<footnote id="2">Bar foo</footnote>
<footnote id="3">Bar</footnote>
<footnote id="4">Foo</footnote>
Then, to replace your existing footnote elements with numeric references, you would have a template like this
<xsl:template match="footnote">
<footnote>
<xsl:value-of select="$footnotes/footnote[. = current()]/#id"/>
</footnote>
</xsl:template>
Try the following XSLT
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:variable name="footnotes">
<xsl:for-each-group select="//footnote" group-by=".">
<footnote id="{position()}">
<xsl:value-of select="."/>
</footnote>
</xsl:for-each-group>
</xsl:variable>
<xsl:template match="/*">
<xsl:apply-templates select="footnote"/>
Footnotes
<xsl:copy-of select="$footnotes"/>
</xsl:template>
<xsl:template match="footnote">
<footnote>
<xsl:value-of select="$footnotes/footnote[. = current()]/#id"/>
</footnote>
</xsl:template>
</xsl:stylesheet>
When applied to your sample XML (assuming a root element), the following is output
<footnote>1</footnote>
<footnote>2</footnote>
<footnote>1</footnote>
<footnote>1</footnote>
<footnote>3</footnote>
<footnote>4</footnote>
Footnotes
<footnote id="1">Foo bar</footnote>
<footnote id="2">Bar foo</footnote>
<footnote id="3">Bar</footnote>
<footnote id="4">Foo</footnote>
As well as failing to use xsl:for-each-group, there are many other things wrong with your code. For example, take this:
<xsl:variable name = "bool">
<xsl:choose>
<xsl:when test="$string = preceding::footnote/text()">
<xsl:text>false</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>true</xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
You can write that as
<xsl:variable name="bool" as="xs:boolean()"
select="$string = preceding::footnote"/>
Then you do this:
<xsl:if test="$bool = 'true'">
<xsl:variable name="footnoteCount">
<xsl:call-template name="getItemNumber">
<xsl:with-param name="node" select="."/>
</xsl:call-template>
</xsl:variable>
</xsl:if>
which is completely useless: the variable goes out of scope as soon as it is declared, so it can never be referenced.
You need to do some background reading about XSLT, there are a lot of ideas you haven't yet grasped.
