I am looking for XSL to transform provided input to expected output.I have just provided sample but actual input xml had more than 1000 nodes and as too many nodes not able to use CDATA section in XSL, could you please help.
Input:
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>
Output:
<note>
<to><![CDATA[Tove]]></to>
<from><![CDATA[Jani]]></from>
<heading><![CDATA[Reminder]]></heading>
<body><![CDATA[Don't forget me this weekend!]]></body>
</note>
You can achieve this by using the cdata-section-elements attribute of the xsl:output element which specifies all the elements that should be output in CDATA sections.
So use the following XSLT-1.0:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" version="1.0" cdata-section-elements="to from heading body" encoding="UTF-8" indent="yes" omit-xml-declaration="yes" />
<!-- Identity template -->
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
See that the cdata-section-elements denotes the elements to from heading body to enclose their content in a CDATA section. The identity template just copies all of the file with regard to this.
If your elements are in a namespace, you have to prefix the element's names in the cdata-section-elements with the appropriate namespace-prefix.
For example, if you have the following XML with a namespace on the root element, all children nodes are in that namespace, too.
<?xml version="1.0" encoding="utf-8"?>
<Bank xmlns="http://xxyy.x.com" Operation="Create">
<Customer type="random">
<CustomerId>Id10</CustomerId>
<CountryCode>CountryCode19</CountryCode>
<LanguageCode>LanguageCode20</LanguageCode>
<AddressArray>
<Address type="primary">
<StreetAddress>179 Alfred St</StreetAddress>
<City>Fortitude Valley</City>
<County>GR</County>
<Country>India</Country>
</Address>
</AddressArray>
</Customer>
</Bank>
Use this XSLT (pay attention to the namespace declaration on the xsl:stylesheet element):
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:ns0="http://xxyy.x.com">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" cdata-section-elements="ns0:CustomerId ns0:CountryCode ns0:LanguageCode ns0:StreetAddress ns0:City ns0:County ns0:Country" omit-xml-declaration="yes" />
<!-- Identity template -->
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Make sure that the namespace of the XSLT matches the namespace of the XML, here both are http://xxyy.x.com, but in your sample XML it is xxyy.x.com.
EDIT 2:
If you have a large amount of elements you can either add them all to cdata-section-elements (maybe by constructing it by another stylesheet) or use the solution I found here: Wrapping all elements in CDATA. It is kind of a hack.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" omit-xml-declaration="yes" />
<xsl:variable name="CDATABegin" select="'<![CDATA['" />
<xsl:variable name="CDATAEnd" select="']]>'" />
<!-- Identity template -->
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*" />
</xsl:copy>
</xsl:template>
<xsl:template match="text()[normalize-space()]">
<xsl:value-of select="$CDATABegin" disable-output-escaping="yes"/>
<xsl:value-of select="." disable-output-escaping="yes"/>
<xsl:value-of select="$CDATAEnd" disable-output-escaping="yes"/>
</xsl:template>
</xsl:stylesheet>
This wraps all non-empty text() nodes in CDATA sections. But here, too, you'd have to mention all elements in template matching rules containing the CDATA wrapping code.
Which variant would be easier to apply depends on the greater scenario.

I want to replace the namespace of the following XML Document
<?xml version="1.0" encoding="UTF-8"?>
<ns0:Document xmlns:ns0="http://mydata.com/H2H/Automation">
<CstmrCdtTrfInitn>
<GrpHdr>
</GrpHdr>
</CstmrCdtTrfInitn>
</ns0:Document>
with the following
<?xml version="1.0" encoding="UTF-8"?>
<Document xmlns="urn:iso:std:iso"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<CstmrCdtTrfInitn>
<GrpHdr>
</GrpHdr>
</CstmrCdtTrfInitn>
</Document>
Any idea about XSLT which can convert this?
I have tried the following XSL, but it is adding the namespace with second Node and also not able to remove first namespace.
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output encoding="UTF-8" indent="yes"/>
<xsl:template match="/*">
<xsl:element name="{local-name()}" namespace="http://www.w3.org/2001/XMLSchema-instance">
<xsl:copy-of select="./*" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Your requirement can be a bit tricky: replacing the default namespace of the Document element is straightforward. But adding the unused xslns:xsi namespace in XSLT-1.0 requires the EXSLT extension and a special technique explained by Michael Kay in reply to this question. It involves creating an unused element in a global variable whose namespace is then copied in the template replacing the default namespace. In XSLT-2.0 and above this would be easier (see below).
The EXSLT extension is not available in all XSLT-1.0 processors. But it is necessary to create a node-set from the variable.
So all namespaces are to be defined in the xsl:stylesheet element, and then the root element (here ns0:Document) is matched by a template and replaced with its local-name() part with the new default namespace added, followed by copying the "dummy" namespace of the element defined in the variable.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns0="http://mydata.com/H2H/Automation" xmlns:urn="urn:iso:std:iso" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ext="http://exslt.org/common">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<!-- identity template (except elements)-->
<xsl:template match="node()[not(self::*)]|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*" />
</xsl:copy>
</xsl:template>
<xsl:variable name="nsXSI">
<xsl:element name="xsi:dummy" namespace="http://www.w3.org/2001/XMLSchema-instance" />
</xsl:variable>
<xsl:template match="ns0:*|*">
<xsl:element name="{local-name()}" namespace="urn:iso:std:iso">
<xsl:copy-of select="ext:node-set($nsXSI)/*/namespace::xsi" />
<xsl:apply-templates select="node() | #*" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Output should be as expected, even in XSLT-1.0:
<Document xmlns="urn:iso:std:iso" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<CstmrCdtTrfInitn>
<GrpHdr>
</GrpHdr>
</CstmrCdtTrfInitn>
</Document>
The simplified solution requires an XSLT-2.0 capable processor. Then you can use the xsl:namespace instruction as follows and don't need the "dummy" variable:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns0="http://mydata.com/H2H/Automation">
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<!-- identity template (except elements)-->
<xsl:template match="node()[not(self::element())]|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*" />
</xsl:copy>
</xsl:template>
<xsl:template match="ns0:*|*">
<xsl:element name="{local-name(.)}" namespace="urn:iso:std:iso">
<xsl:namespace name="xsi">http://www.w3.org/2001/XMLSchema-instance</xsl:namespace>
<xsl:apply-templates select="node() | #*" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
The output is the same.
The above XSLT-2.0 solution could be further simplified by using XSLT-3.0+'s xsl:mode to replace the identity template with
<xsl:mode on-no-match="shallow-copy"/>
Is there a reason why you cannot do simply:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ns0="http://mydata.com/H2H/Automation"
exclude-result-prefixes="ns0">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="*">
<xsl:element name="{local-name()}" namespace="urn:iso:std:iso">
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
<xsl:template match="/ns0:Document">
<Document xmlns="urn:iso:std:iso" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<xsl:apply-templates/>
</Document>
</xsl:template>
</xsl:stylesheet>

Your current template matches * which will match any element, but really you only want it to match the root element.
Additionally, as you want to change Header3 from being in no namespace, to being in the "def.v1" namespace, you should be making use of xsl:apply-templates, not xsl:copy-of
<xsl:template match="/*">
<ns2:Header1 xmlns:ns2="urn:tar:abc" xmlns:v1="def.v1">
<xsl:apply-templates />
</ns2:Header1>
</xsl:template>
You would then need a template matching Header3 to change the namespace
<xsl:template match="Header3" xmlns:v1="def.v1">
<v1:Header3>
<xsl:apply-templates />
</v1:Header3>
</xsl:template>
You would then just need the identity template to copy all other nodes without changes.
Try this XSLT
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs" version="2.0">
<xsl:output method="xml" indent="yes" />
<xsl:template match="/*">
<ns2:Header1 xmlns:ns2="urn:tar:abc" xmlns:v1="def.v1">
<xsl:apply-templates />
</ns2:Header1>
</xsl:template>
<xsl:template match="Header3" xmlns:v1="def.v1">
<v1:Header3>
<xsl:apply-templates />
</v1:Header3>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy copy-namespaces="no">
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
See it in action at http://xsltransform.net/jz1PuQb
Below is an input xml file:
<assets>
<item>
<file_name>file123</file_name>
<description>testing</description>
<created>date</created>
<metadata>
<guest>name</guest>
<webinfo>test</webinfo>
<albumorder>3</albumorder>
<albumorder>3</albumorder>
</metadata>
</item>
</assets>
From the above xml metadata/albumorder is having duplicate. I want to keep only one albumorder element. How to remove the duplicate elements.
Result file should be like:
<assets>
<item>
<file_name>file123</file_name>
<description>testing</description>
<created>date</created>
<metadata>
<guest>name</guest>
<webinfo>test</webinfo>
<albumorder>3</albumorder>
</metadata>
</item>
</assets>
The following copies only elements, which don't have a same named preceeding sibling element:
<?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" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="*">
<xsl:if test="not(preceding-sibling::*[name(.) = name(current())])">
<xsl:copy><xsl:apply-templates/></xsl:copy>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
There is pattern called "XSL identity template" or "XSL identity transformation", that will keep all XML except for rules you define to change certain elements.
kiwiwings already pointed out the solution, I would just integrate it in the identity template, otherwise you would loose XML comments, attributes, and processing instructions (none of them are present in your XML, but someone else may have them).
<xsl:output method="xml" indent="yes" encoding="UTF-8"/>
<xsl:template match="comment()|processing-instruction()|text()">
<xsl:copy/>
</xsl:template>
<xsl:template match="*">
<xsl:if test="not(preceding-sibling::*[name(.) = name(current())])">
<xsl:copy>
<xsl:copy-of select="#*"/>
<xsl:apply-templates select="comment()|processing-instruction()|text()|*"/>
</xsl:copy>
</xsl:if>
</xsl:template>
I need to transform the following xml
<node1 xmlns:ns1="namespace1">
<node2 xmlns:ns2="namespace2">
<node3...>
<node4...>
</node2>
</node1>
To
<NewNode2 xmlns:ns2="namespace2">
<node3...>
<node4...>
</NewNode2>
I use this XSLT
<?xml version="1.0" encoding="utf-16" ?>
<xsl:stylesheet xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:ns1="namespace1"
xmlns:ns2="namespace2">
<xsl:output omit-xml-declaration="yes" method="xml" version="1.0" />
<xsl:template match="/">
<xsl:apply-templates select="/" />
</xsl:template>
<xsl:template match="/" >
<NewNode2>
<xsl:copy-of select="//*[local-name()='node2']" />
</NewNode2 >
</xsl:template>
</xsl:stylesheet>
But this throws error in visual studio -
input validation error - element 'namespace1:node1' not declared
and element 'namespace2:node2' not declared
Your goal van be achieved with the following XSLT:
<?xml version="1.0" encoding="UTF-16"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:ns1="namespace1"
xmlns:ns2="namespace2"
xmlns="namespace2">
<xsl:output omit-xml-declaration="yes" method="xml" version="1.0" />
<xsl:template match="/">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="#*|*">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="ns1:node1">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="ns2:node2">
<ns2:NewNode2>
<xsl:apply-templates />
</ns2:NewNode2>
</xsl:template>
</xsl:stylesheet>
The statement <xsl-templates select="/" /> inside <xsl:stylesheet match="/"> causes an infinite loop, since the matching template for the called 'root' is the template itself, which is calling the root.
The template <xsl template match="#*|*> belongs in almost all stylesheets, because this copies the content of all elements which are not otherwise specified (most applicable selection rule).
The other two templates specify specific behaviour for ns1:node1 (do not output any information at this level, but continue the template matching process for all further levels) and for ns2:node2 (create ns2:NewNode2 and continue to include all other availble information inside).
I need to add an additional namespace to an already namespaced XML file but only if a particular element does not exist.
My XML doc looks like:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<everyone xmlns="AAA" xmlns:ns2="BBB" xmlns:ns3="CCC" company="TestingCorp">
<common>Stuff Here</common>
<ns2:person id="123">
<ns3:firstname>Billy</ns3:firstname>
<ns2:lastname>Bobby</ns2:lastname>
</ns2:person>
</everyone>
... and if there is no ns3:firstname element in the person element, I'd like to add a new namespace and (e.g. xmlns:frog="FFF") and also an additional element within person as shown below:
Desired Output:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<everyone xmlns="AAA" xmlns:ns2="BBB" xmlns:ns3="CCC" xmlns:frog="FFF" company="TestingCorp">
<common>Stuff Here</common>
<ns2:person id="123">
<frog:title>
<Master/>
</frog:title>
<ns2:lastname>Bobby</ns2:lastname>
</ns2:person>
</everyone>
My XSL doc currently is:
<?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" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- Copy Everything -->
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/*">
<xsl:element name="ns:{local-name()}">
<xsl:attribute name="frog">fff</xsl:attribute>
<xsl:apply-templates select="node()|#*" />
</xsl:element>
</xsl:template>
</xsl:stylesheet>
.... unfortunately this does not work.
I've tried lots of different things but can't seem to achieve this using XSLT v1.0. Any help would be greatly appreciated.
First you need to declare the various namespaces in your stylesheet, as well as the "AAA" default namespace
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="AAA"
xmlns:frog="FFF"
xmlns:ns2="BBB"
xmlns:ns3="CCC">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- Copy Everything -->
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<!-- for a Person with no firstname, add a frog:title -->
<xsl:template match="ns2:person[not(ns3:firstname)]">
<xsl:copy>
<!-- must handle attributes before elements/text nodes -->
<xsl:apply-templates select="#*" />
<frog:title>
<Master/>
</frog:title>
<xsl:apply-templates select="node()" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
This will produce
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<everyone xmlns="AAA" xmlns:ns2="BBB" xmlns:ns3="CCC" company="TestingCorp">
<common>Stuff Here</common>
<ns2:person id="123">
<frog:title xmlns:frog="FFF">
<Master/>
</frog:title>
<ns2:lastname>Bobby</ns2:lastname>
</ns2:person>
</everyone>
If the xmlns:frog absolutely must be on the everyone element rather than on each frog:title then you could add another template
<xsl:template match="/*">
<xsl:copy>
<xsl:copy-of select="document('')/xsl:stylesheet/namespace::frog" />
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:template>
to copy the namespace declaration off the stylesheet element (though this would mean that every output document has an xmlns:frog declaration even if it doesn't involve any frog:* elements).
Edit: apparently Xalan doesn't like the copy-of namespaces from document(''), as an alternative, if you know that the document element will always have the same name then you can hard code that as a literal result element
<xsl:template match="/*">
<everyone xmlns:frog="FFF">
<xsl:copy-of select="namespace::*" />
<xsl:apply-templates select="#*|node()" />
</everyone>
</xsl:template>
(technically it will do what you want even without the explicit xmlns:frog in this template, since literal result elements always get the namespace declarations that are in scope at the point in the stylesheet where they are declared, but the intention is arguably clearer if you include it)
This mailing list post gives some possible insights into the reason for document('') not working as it should.
