XSLT 1.0 - Move certain elements into a new parent - xslt

Thank you for taking the time to look at my question
I have a source xml that looks like so
<root>
<a>asdf</a>
<b>asdfdsaf</b>
<c>adfasd</c>
<d>asddf</d>
<e></e>
<others>
<foo>sdfd</foo>
<bar>hghg</bar>
</others>
</root>
I need to wrap certain elements Eg:a,b,c into a new parent and remove empty elements.
so output like so
<root>
<newparent>
<a>asdf</a>
<b>asdfdsaf</b>
<c>adfasd</c>
</newparent>
<d>asddf</d>
<others>
<foo>sdfd</foo>
<bar>hghg</bar>
</others>
</root>
I managed to remove the empty elements using this XSL -
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:strip-space elements="*"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[not(#*) and not(*) and (not(text()) or .=-1)]"/>
<xsl:template match="name">
</xsl:template>
</xsl:stylesheet>
Getting stuck at adding the newparent node. Any pointers/help is much appreciated.

Try it this way:
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="/root">
<xsl:copy>
<newparent>
<xsl:apply-templates select="a|b|c"/>
</newparent>
<xsl:apply-templates select="*[not(self::a or self::b or self::c)]"/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[not(#* or node())]"/>
</xsl:stylesheet>

<xsl:template match="root">
<xsl:copy>
<newparent>
<xsl:copy-of select="a|b|c"/>
</newparent>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="*[.= '' or name() ='a' or name()='b' or name()='c']"/>
check it if it is fullfill your requirement.

XSLT create new tag if exists else update tag if exists

Is there a way for me to update the label element to Selma if "LastName" exists and if the label LastName doesn't exist then add the "LastName" and "label" elements to the XML?
<xml>
<udfs>
<udf>
<desc>FirstName</desc>
<label>Sam</label>
</udf>
<udf>
<desc>LastName</desc>
<label>Selman</label>
</udf>
</udfs>
</xml>
Here's what I have right now:
<xsl:stylesheet>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="node()|#*" />
</xsl:copy>
</xsl:template>
<xsl:template match="udf[desc='LastName']/fieldValue">
<xsl:value-of select="'Selma'"/>
</xsl:template>
<xsl:template match="udf[not(desc='LastName')]">
<desc>LastName</desc>
<label>Selma</label>
</xsl:template>
</xsl:stylesheet>
I think you want to do:
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="udf[desc='LastName']/label">
<label>Selma</label>
</xsl:template>
<xsl:template match="udfs[not(udf/desc='LastName')]">
<xsl:copy>
<xsl:apply-templates/>
<udf>
<desc>LastName</desc>
<label>Selma</label>
</udf>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

xslt for converting one element to attribute among multiple

I have an xml with subelements and need to change one of the subelement to attribute using XSLT 1.0
<TransportationRequest>
<actionCode>01</actionCode>
<ContractConditionCode>DC</ContractConditionCode>
<ShippingTypeCode>17</ShippingTypeCode>
<MovementTypeCode>3</MovementTypeCode>
<DangerousGoodsIndicator>false</DangerousGoodsIndicator>
<DefaultCurrencyCode>SAR</DefaultCurrencyCode>
The Expected xml is as below using the XSLT code:
<TransportationRequest actionCode="01">
<ContractConditionCode>DC</ContractConditionCode>
<ShippingTypeCode>17</ShippingTypeCode>
<MovementTypeCode>3</MovementTypeCode>
<DangerousGoodsIndicator>false</DangerousGoodsIndicator>
<DefaultCurrencyCode>SAR</DefaultCurrencyCode>
First, close the root tag on your xml:
<TransportationRequest>
<actionCode>01</actionCode>
<ContractConditionCode>DC</ContractConditionCode>
<ShippingTypeCode>17</ShippingTypeCode>
<MovementTypeCode>3</MovementTypeCode>
<DangerousGoodsIndicator>false</DangerousGoodsIndicator>
<DefaultCurrencyCode>SAR</DefaultCurrencyCode>
</TransportationRequest>
then this xsl will do what you asked for:
<?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" encoding="UTF-8" />
<xsl:template match="/">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="#*|node()">
<!-- Copy every node as is -->
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="TransportationRequest">
<!-- transform the TransportationRequest node in a special way -->
<xsl:element name="TransportationRequest">
<xsl:attribute name="actionCode"><xsl:value-of select="actionCode" /></xsl:attribute>
<!-- don't transform the actionCode node (is in the attribute) -->
<xsl:apply-templates select="#*|node()[name()!='actionCode']"/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
You could to it like this :
<?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" indent="yes"/>
<xsl:template match="TransportationRequest">
<xsl:copy>
<xsl:attribute name="actionCode">
<xsl:value-of select="actionCode"/>
</xsl:attribute>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="actionCode"/>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Xslt copy element to existing or create new if not exists

Pretty new to xml transformations and i'm stuck at (might be for you) pretty easy task.
Let's suggest we have source:
<root>
<someValue>123</someValue>
</root>
It should be transformed into:
<root>
<additional>
<someValue>123</someValue>
</additional>
</root>
But if we have this as a source:
<root>
<additional>
<b>something</b>
</additional>
<someValue>123</someValue>
</root>
we should move someValue to existing additional, i.e.:
<root>
<additional>
<b>something</b>
<someValue>123</someValue>
</additional>
</root>
Keep in mind that there can be other elements at a level with same behavior (moved under additional).
Well, working example is much appreciated, but if it is accompanied by small description of how it works that would be fantastic (i prefer be tought to fish, rather than just being fed with it).
One possible approach would be to add a additional wrapper as a child of root, and remove the existing additional wrapper - so its children move up to become children of root (or rather children of the added additional wrapper):
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="/root">
<xsl:copy>
<additional>
<xsl:apply-templates/>
</additional>
</xsl:copy>
</xsl:template>
<xsl:template match="additional">
<xsl:apply-templates/>
</xsl:template>
</xsl:stylesheet>
Keep in mind that there can be other elements at a level with same
behavior (moved under additional).
This stylesheet:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="root[additional|someValue]">
<xsl:copy>
<xsl:apply-templates select="#*"/>
<additional>
<xsl:apply-templates select="additional/*|someValue"/>
</additional>
<xsl:apply-templates select="node()[not(self::additional|self::someValue)]"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
With this input:
<root>
<additional>
<b>something</b>
</additional>
<someValue>123</someValue>
<anotherValue>keep</anotherValue>
</root>
Output:
<root>
<additional>
<b>something</b>
<someValue>123</someValue>
</additional>
<anotherValue>keep</anotherValue>
</root>
Do note: just one rule to override the identity transformation. Only process root meeting the conditions (someValue or additional childs). Copying root, applying templates to attributes (to further process), wrapping with an additional element the result of applying templates to additional's childs and root's someValue childs. Finally, applying templates to root's childs, which are not additional nor someValue.
I ended up with following:
<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="/root/additional"/>
<xsl:template match="/root">
<xsl:copy>
<additional>
<xsl:copy-of select="someValue"/>
<xsl:copy-of select="additional/*"/>
</additional>
</xsl:copy>
</xsl:template>
Here we strip original additional and then create it from scratch copying there needed someValue and original content from source (additional/*)
Use for version xslt 2.0
<?xml version="1.0" encoding="UTF-8"?>
<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" omit-xml-declaration="no" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node() except someValue"/>
</xsl:copy>
</xsl:template>
<xsl:template match="additional">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
<xsl:copy-of select="following-sibling::someValue"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

Filter out elements and replace element value in one step

I am trying to filter out elements, and rename element value, but I can't get it to work:
<?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" method="xml"/>
<xsl:template match="xml">
<xsl:copy>
<xsl:for-each select="product[matches(code, 'C17.*[^V]$')]">
<xsl:copy>
<xsl:copy-of select="#*|node()"/>
</xsl:copy>
</xsl:for-each>
</xsl:copy>
</xsl:template>
<xsl:template match="title">
<xsl:copy>
<xsl:value-of select="replace(.,'Apple','Carrot')"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Example input data:
<?xml version="1.0" encoding="UTF-8"?>
<xml>
<product>
<code>C17020</code>
<title>Apple</title>
</product>
<product>
<code>C1723V</code>
<title>Samsung</title>
</product>
</xml>
I want to leave <product>'s starting with C17, but not ending to V. I use C17.*[^V]$ regex for this. This part is working.
The problem is with renaming title function. If I add this step to a new XSLT with code:
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
at the begin, then it works.
What I am doing wrong here?
The problem is you are doing <xsl:copy-of select="#*|node()"/> in your template matching xml. This will copy the attributes and child nodes, buy will not apply any templates. So your template matching title is just not used.
You need to use xsl:apply-templates here, but also include the identity template (the template you mention using in your new XSLT code) which ensures code gets copied too
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output encoding="UTF-8" indent="yes" method="xml"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="xml">
<xsl:copy>
<xsl:for-each select="product[matches(code, 'C17.*[^V]$')]">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:for-each>
</xsl:copy>
</xsl:template>
<xsl:template match="title">
<xsl:copy>
<xsl:value-of select="replace(.,'Apple','Carrot')"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Note you can actually simplify your XSLT. Rather than being explicit in what you want to copy, by using the identity template you can instead have templates to remove what you don't want to copy....
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output encoding="UTF-8" indent="yes" method="xml"/>
<xsl:strip-space elements="*" />
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="product[not(matches(code, 'C17.*[^V]$'))]" />
<xsl:template match="title">
<xsl:copy>
<xsl:value-of select="replace(.,'Apple','Carrot')"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
Another thing to note is that matches and replace is for XSLT 2.0 only.

Remove elements based on other element's value -- XSLT

I have a style-sheet that I am using to remove certain elements based on the value of an other element. However, it is not working ...
Sample Input XML
<Model>
<Year>1999</Year>
<Operation>ABC</Operation>
<Text>Testing</Text>
<Status>Ok</Status>
</Model>
If Operation value is 'ABC' then remove Text and Status nodes from XML.
And gives the following output.
<Model>
<Year>1999</Year>
<Operation>ABC</Operation>
</Model>
Here is my style sheet that I am using but it is removing Text and Status nodes from all XMLs even when operation is not 'ABC'.
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="ID" select="//Operation"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="Text | Status">
<xsl:if test ="$ID ='ABC'">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
Thanks in Advance
How would I do the same when namespace is present like
<ns0:next type="Sale" xmlns:ns0="http://Test.Schemas.Inside_Sales">
Here is a complete XSLT transformation -- short and simple (no variables, no xsl:if, xsl:choose, xsl:when, xsl:otherwise):
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match=
"*[Operation='ABC']/Text | *[Operation='ABC']/Status"/>
</xsl:stylesheet>
When this transformation is applied on the provided XML document:
<Model>
<Year>1999</Year>
<Operation>ABC</Operation>
<Text>Testing</Text>
<Status>Ok</Status>
</Model>
the wanted, correct result is produced:
<Model>
<Year>1999</Year>
<Operation>ABC</Operation>
</Model>
Change your xsl:if as follows:
<xsl:if test="../Operation!='ABC'">
and you can get rid of xsl:variable.
A better pattern in XSLT than using <xsl:if> is to add new templates with match conditions:
<xsl:template match="(Text | Status)[../Operation != 'ABC']"/>
I found this works:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/Model">
<xsl:choose>
<xsl:when test="Operation[text()!='ABC']">
<xsl:copy>
<xsl:apply-templates select="node()|#*"/>
</xsl:copy>
</xsl:when>
<xsl:otherwise>
<xsl:copy>
<xsl:apply-templates select="Year"/>
<xsl:apply-templates select="Operation"/>
</xsl:copy>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
