Is it possible to replace the call-template statement in the following stylesheet with a apply-statement? So that the structure of the templates are nearly the same. With structure I mean that I have a xpath to select a element form the source xml e.g. /shiporder/address/city and I have a target xpath for my output xml e.g. /root/Address/Country then I step reverse through the source path. All /shiporder/address/city goes under Country all /shiporder/address goes under Address and the root shiporder become the tag root.
Source XML:
<shiporder>
<shipto>orderperson1</shipto>
<shipfrom>orderperson2</shipfrom>
<address>
<city>London</city>
</address>
<address>
<city>Berlin</city>
</address>
</shiporder>
Stylesheet:
<xsl:template match="/">
<xsl:apply-templates select="shiporder"/>
</xsl:template>
<xsl:template match="/shiporder">
<root>
<xsl:apply-templates select="address/city"/>
<xsl:call-template name="Identity" />
</root>
</xsl:template>
<xsl:template name="Identity">
<Identity>
<xsl:call-template name="Name" />
</Identity>
</xsl:template>
<xsl:template name="Name">
<Name>
<xsl:apply-templates select="/shiporder/shipto"/>
</Name>
</xsl:template>
<xsl:template match="/shiporder/shipto">
<Last>
<xsl:apply-templates select="text()"/>
</Last>
</xsl:template>
<xsl:template match="/shiporder/address/city">
<Country>
<xsl:apply-templates select="text()"/>
</Country>
</xsl:template>
you can use the following:
<?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" indent="yes" encoding="UTF-8"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/shiporder">
<root>
<xsl:apply-templates select="address/city"/>
<xsl:apply-templates select="shipto"/>
</root>
</xsl:template>
<xsl:template match="shipto">
<Identity>
<Name>
<Last><xsl:value-of select="."/></Last>
</Name>
</Identity>
</xsl:template>
<xsl:template match="/shiporder/address/city">
<Country>
<xsl:value-of select="."/>
</Country>
</xsl:template>
</xsl:stylesheet>
Generally speaking, <xsl:call-template name="..."/> can be turned into a <xsl:apply-templates select="current()" mode="..."/> and <xsl:template match="node()" mode="..."/> (as long as this mode is not used anywhere else).
But there, the upvoted answer is way more suited.

I have a file called ori.xml:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<container>
<elA>
<el1>value1</el1>
<el2>value2</el2>
</elA>
<elB>
<el3>value3</el3>
<el4>value4</el4>
<el5>value5</el5>
</elB>
<elC>
<el6>value5</el6>
</elC>
</container>
</root>
and another one called modifs.xml:
<?xml version="1.0" encoding="UTF-8"?>
<els>
<el2>newvalue2</el2>
<el5>newvalue5</el5>
</els>
and I would like to obtain result.xml:
<?xml version="1.0" encoding="UTF-8"?>
<root>
<container>
<elA>
<el1>value1</el1>
<el2>newvalue2</el2>
</elA>
<elB>
<el3>value3</el3>
<el4>value4</el4>
<el5>newvalue5</el5>
</elB>
<elC>
<el6>value5</el6>
</elC>
</container>
</root>
I'm a beginner in XSLT.
So I started to write a stylesheet with which I'm able to change value2 into newvalue2:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:param name="fileName" select="'modifs.xml'" />
<xsl:param name="modifs" select="document($fileName)" />
<xsl:param name="updateEl" >
<xsl:value-of select="$modifs/els/el2" />
</xsl:param>
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="//elA/el2">
<xsl:copy>
<xsl:apply-templates select="$updateEl" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
But now I have to modify this stylesheet to be able to know which elements are in modifs.xml and find them in ori.xml. I don't know how to do that. Could you help please ?
I would use a key:
<xsl:key name="ref-change" match="els/*" use="local-name()"/>
<xsl:template match="*[key('ref-change', local-name(), $modifs)]">
<xsl:copy-of select="key('ref-change', local-name(), $modifs)"/>
</xsl:template>
However, using the third argument for the key function is only supported in XSLT 2 and later thus if you use an XSLT 1 processor you need to move the logic into the template, that requires using for-each to "switch" the context document
<xsl:template match="*">
<xsl:variable name="this" select="."/>
<xsl:for-each select="$modifs">
<xsl:choose>
<xsl:when test="key('ref-change', local-name($this))">
<xsl:copy-of select="key('ref-change', local-name($this))"/>
</xsl:when>
<xsl:otherwise>
<xsl:for-each select="$this">
<xsl:call-template name="identity"/>
</xsl:for-each>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:template>
Put name="identity" on your identity transformation template.
I'm using a for-each in my XSLT template.
This is my example input XML:
<products>
<data>
<label_1>some_label1</label_1>
<label_2>some_label2</label_2>
<values>
<a>a</a>
<b>b</b>
</values>
</data>
<data>
<label_1>some_label1</label_1>
<label_2>some_label2</label_2>
<values>
<c>c</c>
<d>d</d>
</values>
</data>
</products>
Now based on my template:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns="http:/example.com/ns">
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="data">
<data>
<xsl:variable name="values" select="values" />
<xsl:for-each select="$values">
<xsl:apply-templates select="#*|node()" />
</xsl:for-each>
</data>
</xsl:template>
</xsl:stylesheet>
I get only <values></values> and that is ok for me.
That's my output:
<products>
<data>
<a>a</a>
<b>b</b>
</data>
<data>
<c>c</c>
<d>d</d>
</data>
</products>
What i need in my output is namespace like this:
<products>
<data>
<ns:a>a</ns:a>
<ns:b>b</ns:b>
</data>
<data>
<ns:c>c</ns:c>
<ns:d>d</ns:d>
</data>
</products>
So what i understand is "each element of values is applied by template". How can I add namespace ?
You can get output similar to what you show (albeit well-formed) by using:
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:strip-space elements="*"/>
<!-- identity transform -->
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="data">
<xsl:copy>
<xsl:apply-templates select="values/*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="values/*">
<xsl:element name="ns:{local-name()}" namespace="http:/example.com/ns">
<xsl:value-of select="."/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Or, if you prefer:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ns="http:/example.com/ns">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/products">
<products>
<xsl:for-each select="data">
<xsl:copy>
<xsl:for-each select="values/*">
<xsl:element name="ns:{local-name()}">
<xsl:value-of select="."/>
</xsl:element>
</xsl:for-each>
</xsl:copy>
</xsl:for-each>
</products>
</xsl:template>
</xsl:stylesheet>
Replace http:/example.com/ns with your own namespace URI.

This answer follows the technique used in this SO answer to a similar problem.
Solution
Add namespace information to all descendants of specific elements. Augment the stylesheet by a template matching this set of nodes:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ns="http://my.ns.uri"
>
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="data">
<data>
<xsl:variable name="values" select="values" />
<xsl:for-each select="$values">
<xsl:apply-templates select="#*|node()" />
</xsl:for-each>
</data>
</xsl:template>
<!--
Added template.
-->
<xsl:template match="data//*">
<xsl:element name="ns:{name()}" namespace="http://my.ns.uri">
<xsl:for-each select=".">
<xsl:apply-templates select="#*|node()" />
</xsl:for-each>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
I want to transform a source xml into a target xml where certain matches from the source xml are included in different context in the target xml. For example I have a source xml like:
<shiporder>
<shipto>orderperson1</shipto>
<shipto>orderperson1</shipto>
<city>London</city>
</shiporder>
On this source xml I apply the following stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" encoding="UTF-8"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<xsl:call-template name="root" />
</xsl:template>
<xsl:template name="root">
<root>
<xsl:apply-templates select="/shiporder"/>
<xsl:call-template name="Customer"/>
</root>
</xsl:template>
<xsl:template name="Customer">
<Customer>
<!--<xsl:apply-templates select="/shiporder"/>-->
</Customer>
</xsl:template>
<xsl:template match="/shiporder">
<xsl:apply-templates select="shipto"/>
</xsl:template>
<xsl:template match="/shiporder/shipto">
<Address>
<xsl:apply-templates select="text()"/>
</Address>
</xsl:template>
</xsl:stylesheet>
In the template of name Customer I like to apply a template like:
<xsl:template match="/shiporder">
<xsl:apply-templates select="city"/>
</xsl:template>
<xsl:template match="/shiporder/city">
<City>
<xsl:apply-templates select="text()"/>
</City>
</xsl:template>
But I already defined a template with match /shiporder. So I don't know how to design a stylesheet where both templates with the same match exists in their own context?
If you use mode, like #michael.hor257k suggested you can differentiate between two or more templates that match on the same element but with different results.
In your case that could end up looking like this:
<?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" indent="yes" encoding="UTF-8"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<xsl:call-template name="root" />
</xsl:template>
<xsl:template name="root">
<root>
<xsl:apply-templates select="/shiporder" mode="root"/>
<xsl:call-template name="Customer"/>
</root>
</xsl:template>
<xsl:template name="Customer">
<Customer>
<xsl:apply-templates select="/shiporder" mode="customer"/>
</Customer>
</xsl:template>
<xsl:template match="/shiporder" mode="root">
<xsl:apply-templates select="shipto"/>
</xsl:template>
<xsl:template match="/shiporder" mode="customer">
<xsl:apply-templates select="city"/>
</xsl:template>
<xsl:template match="shipto">
<Address>
<xsl:apply-templates select="text()"/>
</Address>
</xsl:template>
<xsl:template match="city">
<City>
<xsl:apply-templates select="text()"/>
</City>
</xsl:template>
</xsl:stylesheet>
Obviously all credits here go to Michael for pointing this out first.
I'm working on a Java based xsl-transformation (XSLT 2.0, could also be XSLT 3.0 if there is a free processor for java) with different input xml files. one input file could look like this:
<?xml version="1.0" encoding="UTF-8"?>
<TEST>
<MyElement>
<CHILD>A</CHILD>
<CHILDBEZ>ABEZ</CHILDBEZ>
<NotInteresting></NotInteresting>
</MyElement>
<MyElement>
<CHILD>B</CHILD>
<CHILDBEZ>BBEZ</CHILDBEZ>
<NotInteresting2></NotInteresting2>
</MyElement>
</TEST>
I want to copy all elements but "NotInteresting" and rename the two nodes CHILD and CHILDBEZ based on two parameters that I get from a mapping file:
the xpath expression that tells me where the text of interest is placed (in this case: TEST/MyFirstElement/CHILD and TEST/MyFirstElement/CHILDBEZ)
and the names of the elements what they should have in the output file (in this case: childName and childBez)
the mapping file:
<?xml version="1.0" encoding="UTF-8"?>
<element root="TEST">
<childName>TEST/MyElement/CHILD</childName>
<childBez>TEST/MyElement/CHILDBEZ</childBez>
</element>
desired output:
<TEST>
<MyElement>
<childName>A</childName>
<childBez>ABEZ</childBez>
</MyElement>
<MyElement>
<childName>B</childName>
<childBez>BBEZ</childBez>
</MyElement>
</TEST>
what I have so far:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:transform version="2.0 "
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.apoverlag.at"
xmlns:apo="http://www.apoverlag.at">
<xsl:variable name="vars" select="document('mapping.xml')"/>
<xsl:param name="src" />
<xsl:variable name="path" xpath-default-namespace="" select="$src/path"/> <!-- = TEST/*-->
<xsl:template match="/">
<xsl:for-each select="$path">
<xsl:call-template name="buildNode">
<xsl:with-param name="currentNode" select="current()"></xsl:with-param>
</xsl:call-template>
</xsl:for-each>
</xsl:template>
<xsl:template name="buildNode">
<xsl:param name="currentNode" />
<xsl:element name="test">
<xsl:for-each select="$vars/element/#root">
<xsl:for-each select="$vars/element/*">
<xsl:element name="{name(.)}"> <xsl:value-of select="concat($currentNode,'/',current())" />
</xsl:element>
</xsl:for-each>
</xsl:for-each>
</xsl:element>
</xsl:template>
</xsl:transform>
My problem is that:
<xsl:value-of select="concat($currentNode,'/',current())" />
gives me "/TEST/MyFirstElement/CHILD" when I try it hardcoded with:
<xsl:value-of select="$currentNode/CHILD" />
I receive my desired output. Can anyone give me a hint how to solve this problem?
I would suggest a radically different approach. To simplify, I have used a mapping document with full paths (starting with the / root node):
mapping xml
<element root="TEST">
<childName>/TEST/MyElement/CHILD</childName>
<childBez>/TEST/MyElement/CHILDBEZ</childBez>
</element>
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:strip-space elements="*"/>
<xsl:param name="mapping" select="document('mapping.xml')"/>
<xsl:key name="map" match="*" use="." />
<xsl:template match="/">
<xsl:variable name="first-pass">
<xsl:apply-templates mode="first-pass"/>
</xsl:variable>
<xsl:apply-templates select="$first-pass/*"/>
</xsl:template>
<xsl:template match="*" mode="first-pass">
<xsl:param name="parent-path"/>
<xsl:variable name="path" select="concat($parent-path, '/', name())" />
<xsl:variable name="replacement" select="key('map', $path, $mapping)" />
<xsl:element name="{if ($replacement) then name($replacement) else name()}">
<xsl:attribute name="original" select="not($replacement)"/>
<xsl:apply-templates mode="first-pass">
<xsl:with-param name="parent-path" select="$path"/>
</xsl:apply-templates>
</xsl:element>
</xsl:template>
<xsl:template match="*">
<xsl:copy>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[#original='true' and not(descendant::*/#original='false')]"/>
</xsl:stylesheet>
Result, when applied to the provided input:
<?xml version="1.0" encoding="UTF-8"?>
<TEST>
<MyElement>
<childName>A</childName>
<childBez>ABEZ</childBez>
</MyElement>
<MyElement>
<childName>B</childName>
<childBez>BBEZ</childBez>
</MyElement>
</TEST>
I have some XML like this:
<root>
<do-not-sort>
<z/>
<y/>
</do-not-sort>
<sortable>
<e f="fog" h="bat" j="cat">
<n n="p"/>
<m n="p"/>
</e>
<d b="fop" c="bar" k="cab">
<m o="p"/>
<m n="p"/>
</d>
</sortable>
</root>
I want to sort the children of the "sortable" element by their textual representation, to end up with this:
<root>
<do-not-sort>
<z/>
<y/>
</do-not-sort>
<sortable>
<d b="fop" c="bar" k="cab">
<m n="p"/>
<m o="p"/>
</d>
<e f="fog" h="bat" j="cat">
<m n="p"/>
<n n="p"/>
</e>
</sortable>
</root>
I am currently doing this by applying the following XSLT template:
<?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" indent="yes" encoding="UTF-8" />
<xsl:template match="#* | /">
<xsl:copy>
<xsl:apply-templates select="#* | node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="*">
<xsl:copy>
<xsl:apply-templates select="#*" />
<xsl:value-of select="normalize-space(text()[1])" />
<xsl:apply-templates select="*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="sortable//*">
<xsl:copy>
<xsl:apply-templates select="#*" />
<xsl:value-of select="normalize-space(text()[1])" />
<xsl:apply-templates select="*">
<xsl:sort data-type="text" select="local-name()" />
<xsl:sort data-type="text" select="#*" />
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
The sorting works correctly, but if the sorted elements have a lot of attributes, the later attributes each wrap onto a new line, for example:
<sortable>
<this is="an" element="with" a="lot" of="attributes"
and="the"
excess="ones"
each="wrap"
onto="their"
own="line"/>
How do I keep all these attributes on the same line, i.e.
<sortable>
<this is="an" element="with" a="lot" of="attributes" and="the" excess="ones" each="wrap" onto="their" own="line"/>
How do I keep all these attributes on
the same line
In your code, replace:
<xsl:output method="xml" indent="yes" encoding="UTF-8" />
with
<xsl:output method="xml" encoding="UTF-8" />
Of course, this will produce the complete output on a single line! At the moment of writing this XSLT 2.0 still doesn't have a finer grained control over the serialization of the output.
In case you need some elements indented and some not, then you will have to provide your own post-processing (and this post-processing may be easier to write with something different from XSLT).
Update:
Actually, using Saxon 9.1.07 and
<xsl:output method="html" encoding="UTF-8" />
where the complete transformation is:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" encoding="UTF-8" />
<xsl:template match="#* | /">
<xsl:copy>
<xsl:apply-templates select="#* | node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="*">
<xsl:copy>
<xsl:apply-templates select="#*" />
<xsl:value-of select="normalize-space(text()[1])" />
<xsl:apply-templates select="*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="sortable//*">
<xsl:copy>
<xsl:apply-templates select="#*" />
<xsl:value-of select="normalize-space(text()[1])" />
<xsl:apply-templates select="*">
<xsl:sort data-type="text" select="local-name()" />
<xsl:sort data-type="text" select="#*" />
</xsl:apply-templates>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
and the source XML document is:
<root>
<do-not-sort>
<z></z>
<y></y>
</do-not-sort>
<sortable>
<this is="an" element="with" a="lot" of="attributes" and="the" excess="ones" each="wrap" onto="their" own="line"></this>
<e f="fog" h="bat" j="cat"></e>
<d b="fop" c="bar" k="cab"></d>
<d b="foo" c="baz" k="cap"></d>
</sortable>
</root>
I get the output with the wanted indentation:
<root>
<do-not-sort>
<z></z>
<y></y>
</do-not-sort>
<sortable>
<this is="an" element="with" a="lot" of="attributes" and="the" excess="ones" each="wrap" onto="their" own="line"></this>
<e f="fog" h="bat" j="cat"></e>
<d b="fop" c="bar" k="cab"></d>
<d b="foo" c="baz" k="cap"></d>
</sortable>
</root>
If you are using Saxon, and want to avoid everything being on one line, you can use the 'line-length' attribute, like this:
<xsl:output xmlns:saxon="http://saxon.sf.net/" indent="yes" saxon:line-length="2000"/
However, be aware that this only works on the Saxon PE (Professional) edition. See here for details:
http://www.saxonica.com/products/products.xml
If you are using the HE (Home) version, you will get an error like this:
Transformation failed: Requested feature (custom serialization {http://saxon.sf.net/}line-length) requires Saxon-PE
