Could anyone help me with an XSLT to convert an XSD from Venetian Blind to Russian Doll design? I read an article on Stack Overflow about the reverse: Russian doll to Venetian blind xsl transformation
With a lot of help from a colleague, I finally got an answer. It may not be elegant, but it meets my immediate needs, here it is:

I'm struggling to get this abomination called XSLT to work. I need to get an EXACT attribute at EXACT path, pass its original value to a template and rewrite this value with the result from the template.
I'm having a file like this:
<?xml version="1.0" encoding="windows-1251"?>
<File>
<Document ReportYear="17">
...
...
</Document>
</File>
So I made an XSLT like this:
<?xml version="1.0" encoding="windows-1251"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl">
<xsl:output method="xml" encoding="windows-1251" indent="yes" />
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()" />
</xsl:copy>
</xsl:template>
<xsl:template name="formatYear">
<xsl:param name="year" />
<xsl:value-of select="$year + 2000" />
</xsl:template>
<xsl:template match="File/Document">
<xsl:copy>
<xsl:apply-templates select="#*" />
<xsl:attribute name="ReportYear">
<xsl:call-template name="formatYear">
<xsl:with-param name="year" select="#ReportYear" />
</xsl:call-template>
</xsl:attribute>
</xsl:copy>
<xsl:apply-templates />
</xsl:template>
</xsl:stylesheet>
This works fine except it closes the <Document> tag immediately and places its content immediately after itself.
Also, can I address the ReportYear attribute value without repeating it twice? I tried current() but it didn't work.
If you're closing <xsl:copy> before applying templates to the remainder of the content of <Document>, then of course <Document> will be closed before the remainder of the content of <Document> appears in the output.
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
exclude-result-prefixes="msxsl"
>
<xsl:output method="xml" encoding="windows-1251" indent="yes" />
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="Document">
<xsl:copy>
<xsl:apply-templates select="#*" />
<xsl:attribute name="ReportYear">
<xsl:value-of select="#ReportYear + 2000" />
</xsl:attribute>
<xsl:apply-templates select="node()" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
outputs
<?xml version="1.0" encoding="windows-1251"?>
<File>
<Document ReportYear="2017">
...
...
</Document>
</File>
I don't think an extra template just for adding 2000 to #ReportYear is necessary. But if you must, you can streamline the whole thing like so
<xsl:template name="formatYear">
<xsl:param name="year" select="#ReportYear" /> <!-- you can define a default value -->
<xsl:value-of select="$year + 2000" />
</xsl:template>
and
<xsl:attribute name="ReportYear">
<xsl:call-template name="formatYear" /> <!-- ...and can use it implicitly here -->
</xsl:attribute>
If you need to process the contents of the Document element with apply-templates and want to keep the result of the applied templates as the children then you need to move the apply-templates inside of the copy:
<xsl:template match="File/Document">
<xsl:copy>
<xsl:apply-templates select="#*"/>
<xsl:attribute name="ReportYear">
<xsl:call-template name="formatYear">
<xsl:with-param name="year" select="#ReportYear"/>
</xsl:call-template>
</xsl:attribute>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
Not sure why you haven't simply used
<xsl:template match="File/Document/#ReportYear">
<xsl:attribute name="{name()}">
<xsl:value-of select=". + 2000"/>
</xsl:attribute>
</xsl:template>
together with the identity transformation template.
I have a XML file where elements B are inside elements A and I want to move them up. From:
<?xml version="1.0" encoding="utf-8"?>
<root>
<A>
<C>Text</C>
Text again
More text
<D>Other text</D>
<B>Text again</B>
<C>No</C>
<D>May be</D>
<B>What?</B>
</A>
<A>
Something
<B>Nothing</B>
<D>Again</D>
<B>Content</B>
End
</A>
</root>
I would like to have:
<?xml version="1.0" encoding="utf-8"?>
<root>
<A>
<C>Text</C>
Text again
More text
<D>Other text</D>
</A>
<B>Text again</B>
<A>
<C>No</C>
<D>May be</D>
</A>
<B>What?</B>
<A>
Something
</A>
<B>Nothing</B>
<A>
<D>Again</D>
</A>
<B>Content</B>
<A>
End
</A>
</root>
The closest XSLT program I have is this:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs" version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="A">
<xsl:for-each select="*">
<xsl:choose>
<xsl:when test="name()='B'">
<xsl:apply-templates select="."/>
</xsl:when>
<xsl:otherwise>
<xsl:element name="A">
<xsl:apply-templates select="."/>
</xsl:element>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
It has two problems: it ignores text nodes (this is probably just a matter of adding |text() to the select="*") but, more important, it creates a element for each node while I would like them to stay together under one . For instance, the above stylesheet makes:
<A><C>No</C></A>
<A><D>May be</D></A>
where I want:
<A><C>No</C>
<D>May be</D></A>
In my XML files, are always direct children of , and there is no or nesting.
The main use case is producing HTML where UL and OL cannot be inside a P.
This question is related but not identical to xslt flattening out child elements in a DocBook para element (and may be also to Flatten xml hierarchy using XSLT
)
As I said in the comment to your question, this is not about moving elements up in hierarchy. It is about grouping nodes, and creating a new parent A element for each group determined by the dividing B element.
In XSLT 1.0 this can be achieved using a so-called sibling recursion:
XSLT 1.0
<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="/root">
<xsl:copy>
<xsl:apply-templates select="A"/>
</xsl:copy>
</xsl:template>
<xsl:template match="A">
<xsl:copy>
<xsl:apply-templates select="node()[1][not(self::B)]" mode="sibling"/>
</xsl:copy>
<xsl:apply-templates select="B[1]" mode="sibling"/>
</xsl:template>
<xsl:template match="node()" mode="sibling">
<xsl:copy-of select="." />
<xsl:apply-templates select="following-sibling::node()[1][not(self::B)]" mode="sibling"/>
</xsl:template>
<xsl:template match="B" mode="sibling">
<xsl:copy-of select="." />
<xsl:if test="following-sibling::node()[normalize-space()]">
<A>
<xsl:apply-templates select="following-sibling::node()[1][not(self::B)]" mode="sibling"/>
</A>
<xsl:apply-templates select="following-sibling::B[1]" mode="sibling"/>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
An XSLT-1.0 solution - which is quite ugly - is the following. The output is as desired, but only for this simple MCVE. A general solution would be far more complicated as #michael.hor257k mentioned in the comments. Without more data it is unlikely to create a better solution in XSLT-1.0. Solutions for XSLT-2.0 and above may simplify this.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/root">
<xsl:copy>
<xsl:for-each select="A">
<xsl:if test="normalize-space(text()[1])">
<A>
<xsl:copy-of select="text()[1]" />
</A>
</xsl:if>
<xsl:if test="preceding::*">
<xsl:copy-of select="B[1]" />
</xsl:if>
<A>
<xsl:copy-of select="C[1] | C[1]/following-sibling::text()[1] | D[1]" />
</A>
<xsl:if test="not(preceding::*)">
<xsl:copy-of select="B[1]" />
</xsl:if>
<A>
<xsl:copy-of select="C[2] | C[2]/following-sibling::text()[1]" />
<xsl:if test="D[2]">
<xsl:copy-of select="D[2]" />
</xsl:if>
</A>
<xsl:copy-of select="B[2]" />
<xsl:if test="normalize-space(text()[last()])">
<A>
<xsl:copy-of select="text()[last()]" />
</A>
</xsl:if>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Concerning the situation of
<A><C>No</C></A>
<A><D>May be</D></A>
It is handled appropriately in the above code. So its output is
<A>
<C>No</C>
<D>May be</D>
</A>
Easy in XSLT 2 or 3 with group-adjacent=". instance of element(B)" or group-adjacent="boolean(self::B)", here is an XSLT 3 example (XSLT 3 is supported by Saxon 9.8 or 9.9 on Java and .NET (https://sourceforge.net/projects/saxon/files/Saxon-HE/) and by Altova since 2017 releases):
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="#all"
version="3.0">
<xsl:mode on-no-match="shallow-copy"/>
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="A">
<xsl:for-each-group select="node()" group-adjacent=". instance of element(B)">
<xsl:choose>
<xsl:when test="current-grouping-key()">
<xsl:apply-templates select="current-group()"/>
</xsl:when>
<xsl:otherwise>
<xsl:copy select="..">
<xsl:apply-templates select="current-group()"/>
</xsl:copy>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
https://xsltfiddle.liberty-development.net/gWmuiKv
In XSLT 2 you need to spell out the <xsl:mode on-no-match="shallow-copy"/> as the identity transformation template and use xsl:element instead xsl:copy:
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="A">
<xsl:for-each-group select="node()" group-adjacent=". instance of element(B)">
<xsl:choose>
<xsl:when test="current-grouping-key()">
<xsl:apply-templates select="current-group()"/>
</xsl:when>
<xsl:otherwise>
<xsl:element name="{name(..)}" namespace="{namespace-uri(..)}">
<xsl:apply-templates select="current-group()"/>
</xsl:element>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:template>
</xsl:transform>

Input XML is this:
<input>
<foo>John's bar</foo>
<bar>test</bar>
<foobar>testing</foobar>
</input>
After XSL transformation:
<input>
<foo>John's bar</foo>
<bar>this_test</bar>
</input>
But the legacy system expects:
<foo>John's bar</foo>
not <foo>John's bar</foo>
So I want to retain the value under <foo> as is rather than let XSLT parse it.
I tried using <xsl:output method="text"/> but with no luck of success..
I think XML itself when loaded gets parsed and XSLT just outputs as is..
If that's true I atleast want to escape it and make ' irrespective of whether it was &apose or ' in the input XML.
XSLT that I tried is this:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:output method="xml"/>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="bar">
<xsl:copy>
<xsl:text>this_</xsl:text>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="foobar"/>
</xsl:stylesheet>
If you are limited to XSLT 1.0, use disable-output-escaping="yes". This attribute can be used on xsl:text and xsl:value-of elements and it is deprecated in XSLT 2.0.

The XSLT 1.0 solution makes use of advice given by Dimitre Novatchev here and Mads Hansen's answer here.
The XSLT 2.0 solution is more elegant, use a character-map to control the serialization of output. Make sure you escape the ampersand character as well (' instead of ').

if <tps_quote_type> is 'Comparison' then change the value of <quote_type> to 'Comparison' and the <tpsdata> field should be removed. The output should look like below.

Maybe you noticed that your handling of those elements with a namespace is a little painful. Just add the http://www.origoservices.com namespace to your XSLT and the pain goes away.

Notes
Most of your "plumbing" is not necessary.
Template match expressions don't need to be a full path.
Use match expressions rather than <xsl:choose> to pinpoint elements you want to change.
Start with a basic identity template, overriding it as needed with more specific templates. This makes your live much easier than starting with a modified identity template.
Use empty templates to remove specific elements.

Now I have an XML file as below:
<DM Name="A DM">
<DV id="SQL:Select something from db" Name="DV 1">
<Sample aid="SQL:Select something from db" />
</DV>
<DV id="SQL:Select something from db" Name="DV 2">
<Sample aid="SQL:Select something from db" name ="DC">
good
</Sample>
</DV>
</DM>
I want to use an XSLT to transform it, there is a parameter in this tamplet to determine which DV should be transformed: if the parameter($dvIndex = 0), then just keep all the elements and attributes, just transform the attriform the attritributes with the value started with "SQL:", if ($dvindext > 0), just transform the specific DV,(remove other DV). Now I write the XSLT as below, but it miss the DM's attributes, I don't know how to copy DM's attributes. I donot know if there is better solution. XML File:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
xmlns:user="urn:my-scripts"
>
<xsl:output method="xml" indent="yes"/>
<msxsl:script language="C#" implements-prefix="user">
<![CDATA[
public string UpperCase(string value){
return value.ToUpper();
}
]]>
</msxsl:script>
<xsl:param name="dvIndex" select="2" />
<xsl:template match="DM" >
<xsl:copy>
<xsl:choose>
<xsl:when test="$dvIndex > 0">
<xsl:apply-templates select="DV[$dvIndex]"/>
</xsl:when>
<xsl:otherwise>
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:otherwise>
</xsl:choose>
</xsl:copy>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<!--[starts-with(translate(substring(.,1,4),'SQL:','sql:'),'sql:')]-->
<xsl:template match="#*[user:UpperCase(substring(.,1,4))='SQL:']">
<xsl:attribute name="{name()}">
<xsl:value-of select="'parsedSQL'"/>
</xsl:attribute>
</xsl:template>
</xsl:stylesheet>
this question is also related to my question 2# (How to only convert an XML file's attribute using XSLT, and leave the other content?)
Thanks very much!
This stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:param name="dvIndex" select="2" />
<xsl:template match="DM" >
<xsl:copy>
<xsl:apply-templates select="#*|DV[$dvIndex]"/>
</xsl:copy>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="#*[starts-with(translate(substring(.,1,4),'SQL:','sql:'),'sql:')]">
<xsl:attribute name="{name()}">
<xsl:value-of select="'parsedSQL'"/>
</xsl:attribute>
</xsl:template>
</xsl:stylesheet>
Result:
<DM Name="A DM">
<DV id="parsedSQL" Name="DV 2">
<Sample aid="parsedSQL" name="DC">
good
</Sample>
</DV>
</DM>
With param dvIndex in 0:
<DM Name="A DM"></DM>
Note: Avoid scripting: it's not standar, it'll force to load script engine every time is used.
EDIT: If you want to process every DV when $dvIndex is 0, then this stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:param name="dvIndex" select="2" />
<xsl:template match="DM" >
<xsl:copy>
<xsl:apply-templates select="#*|DV[$dvIndex]|DV[not($dvIndex)]"/>
</xsl:copy>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="#*[starts-with(translate(substring(.,1,4),'SQL:','sql:'),'sql:')]">
<xsl:attribute name="{name()}">
<xsl:value-of select="'parsedSQL'"/>
</xsl:attribute>
</xsl:template>
</xsl:stylesheet>
With $dvIndex is 0, output:
<DM Name="A DM">
<DV id="parsedSQL" Name="DV 1">
<Sample aid="parsedSQL"></Sample>
</DV>
<DV id="parsedSQL" Name="DV 2">
<Sample aid="parsedSQL" name="DC">
good
</Sample>
</DV>
</DM>
The following probably does what you need. Note the additional <xsl:apply-templates select="#*" /> to copy the attributes.
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
xmlns:user="urn:my-scripts">
<xsl:output method="xml" indent="yes"/>
<msxsl:script language="C#" implements-prefix="user">
<![CDATA[
public string UpperCase(string value){
return value.ToUpper();
} ]]>
</msxsl:script>
<xsl:param name="dvIndex" select="0" />
<xsl:template match="DM" >
<xsl:copy>
<xsl:apply-templates select="#*" />
<xsl:choose>
<xsl:when test="$dvIndex > 0">
<xsl:apply-templates select="DV[$dvIndex]"/>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="DV"/>
</xsl:otherwise>
</xsl:choose>
</xsl:copy>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<!--[starts-with(translate(substring(.,1,4),'SQL:','sql:'),'sql:')]-->
<xsl:template match="#*[user:UpperCase(substring(.,1,4))='SQL:']">
<xsl:attribute name="{name()}">
<xsl:value-of select="'parsedSQL'"/>
</xsl:attribute>
</xsl:template>
</xsl:stylesheet>
