I have this simplified xml:
<?xml version="1.0" encoding="UTF-8"?>
<a>
<b>
<c>
<d>1</d>
<e>2</e>
</c>
</b>
<f>
<g>3</g>
</f>
</a>
This is the xslt i try to apply:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="a">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="b">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="c">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="d">
</xsl:template>
</xsl:stylesheet>
When I apply this sheet, I get output 2 3, which are the remaining textnodes. I've read about the built-in templates which get applied if it can't find a matching template, but in this case, it should find a template?
What is going on?
Edit:
In this case, i would expect to see nothing, because the templates are empty. But i get 2 3 in stead.
When you do <xsl:template match="d">, you tell the processor to ignore all nodes under <d>.
All other nodes are processed with default rules, including the text() one, which is to print the text.
That's why you see 23, and not 1.
Start from the root:
<xsl:template match="/a">
And specify either a mode (so that the default template does not get called, because it does not find a template for e, f and g) or define your own * template which does nothing at the end of the stylesheet:
<xsl:template match="*"/>

I have a simple XML response, like
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<searchRetrieveResponse xmlns="http://www.loc.gov/zing/srw/">
<numberOfRecords>1</numberOfRecords>
<records>
<record>
<recordData>
<kitodo xmlns="http://meta.kitodo.org/v1/">
<metadata name="key1">value1</metadata>
<metadata name="key2">value2</metadata>
<metadata name="key3">value3</metadata>
</kitodo>
</recordData>
</record>
</records>
</searchRetrieveResponse>
which I want to transform to this by XSLT
<?xml version="1.0" encoding="utf-8"?>
<mets:mdWrap xmlns:kitodo="http://meta.kitodo.org/v1/"
xmlns:mets="http://www.loc.gov/METS/"
xmlns:srw="http://www.loc.gov/zing/srw/"
MDTYPE="OTHER"
OTHERMDTYPE="Kitodo">
<mets:xmlData>
<kitodo:kitodo>
<kitodo:metadata name="key1">value1</kitodo:metadata>
<kitodo:metadata name="key2">value2</kitodo:metadata>
<kitodo:metadata name="key3">value3</kitodo:metadata>
</kitodo:kitodo>
</mets:xmlData>
</mets:mdWrap>
That is, I want to remove the outside tree searchRetrieveResponse/records/record/recordData, replace it with mdWrap/xmlData and move the contained data node there.
I have a quite short XSLT for it:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:kitodo="http://meta.kitodo.org/v1/" xmlns:mets="http://www.loc.gov/METS/" xmlns:srw="http://www.loc.gov/zing/srw/">
<xsl:output method="xml" indent="yes" encoding="utf-8"/>
<xsl:strip-space elements="*"/>
<xsl:template match="srw:recordData">
<mets:mdWrap MDTYPE="OTHER" OTHERMDTYPE="Kitodo">
<mets:xmlData>
<xsl:apply-templates select="#*|node()"/>
</mets:xmlData>
</mets:mdWrap>
</xsl:template>
<!-- pass-through rule -->
<xsl:template match="#*|node()">
<xsl:apply-templates select="#*|node()"/>
</xsl:template>
</xsl:stylesheet>
However, what I get is:
<?xml version="1.0" encoding="utf-8"?>
<mets:mdWrap xmlns:kitodo="http://meta.kitodo.org/v1/"
xmlns:mets="http://www.loc.gov/METS/"
xmlns:srw="http://www.loc.gov/zing/srw/"
MDTYPE="OTHER"
OTHERMDTYPE="Kitodo">
<mets:xmlData/>
</mets:mdWrap>
Obviously, the template match="srw:recordData" does match, otherwise I would get an empty result. However, the contained apply-templates doesn’t output anything. (I also tried an <xsl:apply-templates/> without a select="" attribute, but it doesn’t output anything either.) What am I missing?
XSLT processor is net.sf.saxon.TransformerFactoryImpl (Java)
I think nothing happens when you are applying templates inside xmlData. There are no templates that would match descendant nodes.
Try using copy-of:
<xsl:template match="srw:recordData">
<mets:mdWrap MDTYPE="OTHER" OTHERMDTYPE="Kitodo">
<mets:xmlData>
<xsl:copy-of select="kitodo:kitodo"/>
</mets:xmlData>
</mets:mdWrap>
</xsl:template>
The problem is not with the xsl:apply-templates instruction. It is with the template being applied. Your "pass-through rule" does not write anything to the output. You probably meant to have the identity transform template in that place - which goes like this:
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
I want to check to contain only characters + space and <p> nodes inside <used>.
Input:
<root>
<used><p>String 1</p></used>
<used>string 2<p>string 3</p></used>
<used>string 4</used>
<used><image>aaa.jpg</image>para</used>
The output should be:
<ans>
<abc>string 1</abc>
<abc>string 4</abc>
</ans>
Tried code:
<ans>
<abc>
<xsl:template match="root">
<xsl:choose>
<xsl: when test="getCode/matches(text(),'^[a-zA-Z0-9]+$')">
<xsl:text>text()</xsl:text>
</xsl:when>
</xsl:choose>
</xsl:template>
</abc>
</ans>
My tried code is not working as I am expecting. How can I fix this? Thank you. I am using XSLT 2.0
You can use the following XSLT-2.0 stylesheet to get the desired result:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl= "http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<!-- Handle the <root> element -->
<xsl:template match="/root">
<ans>
<xsl:apply-templates select="used" />
</ans>
</xsl:template>
<!-- Create <abc> elements for every matching element -->
<xsl:template match="used[not(*) and matches(text(),'^[\sa-zA-Z0-9]+$')] | used[not(text()) and matches(p/text(),'^[\sa-zA-Z0-9]+$')]/p">
<abc><xsl:copy-of select="text()" /></abc>
</xsl:template>
<!-- Remove all spurious text nodes -->
<xsl:template match="text()" />
</xsl:stylesheet>
Its result is
<?xml version="1.0" encoding="UTF-8"?>
<ans>
<abc>String 1</abc>
<abc>string 4</abc>
</ans>
I've searched through similar questions, but couldn't make any of the suggestions to work. I have the following xml I need to modify it
<XDB>
<ROOT>
<KEY><ID>12345</ID><DATE>5/10/2011</DATE></KEY>
<PERSONAL><ID>1</ID><INFO><LASTNAME>Smith</LASTNAME>...</INFO></PERSONAL>
<CONTACT><ID>1</ID><EMAIL>asmith#yahoo.com</EMAIL>...</CONTACT>
</ROOT>
<ROOT>
<KEY><ID>98765</ID><DATE>5/10/2013</DATE></KEY>
<CONTACT><ID>2</ID><EMAIL>psmithton#yahoo.com</EMAIL>...</CONTACT>
</ROOT>
...
</XDB>
And it needs to look like this:
<XDB>
<ROOT>
<KEY><ID>12345</ID><DATE>5/10/2011</DATE>
<PERSONAL><ID>1</ID><INFO><LASTNAME>Smith</LASTNAME>...</INFO></PERSONAL>
<CONTACT><ID>1</ID><EMAIL>asmith#yahoo.com</EMAIL>...</CONTACT>
</KEY>
</ROOT>
<ROOT>
<KEY><ID>98765</ID><DATE>5/10/2013</DATE>
<CONTACT><ID>2</ID><EMAIL>psmithton#yahoo.com</EMAIL>...</CONTACT>
</KEY>
</ROOT>
...
</XDB>
I need to make 2...n siblings as children of the first 'key' sibling. Essentially, i need to remove the closing < /KEY> and put it before the closing < /ROOT>. I would appreciate your help.
Thanks.
Following xslt based on Identity transform could make this job
<?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"/>
<!-- Copy everything you find... -->
<xsl:template match="node()|#*">
<xsl:copy>
<xsl:apply-templates select="node()|#*" />
</xsl:copy>
</xsl:template>
<!-- ... but if you find first element inside ROOT ... -->
<xsl:template match="ROOT/node()[1]">
<xsl:copy>
<xsl:apply-templates select="node()|#*" />
<!-- ... copy its sibling into it ... -->
<xsl:copy-of select="following-sibling::*" />
</xsl:copy>
</xsl:template>
<!-- ignore other elements inside ROOT element since they are copied in template matching first element -->
<xsl:template match="ROOT/node()[position() > 1]" />
</xsl:stylesheet>
Here is my example document
<a >
<b flag='foo'>
<c/>
<d/>
</b>
</a>
I am looking to remove the "c" element only when the flag attribute on b is 'bar'.
Ie if flag='foo' the "c" element should not be removed. I do not currently have an xsl debugging tool on my pc, and have been unable to find an online tool that shows xslt error information, and have been running the following test xsl transform on http://xslttest.appspot.com/ :
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml" indent="yes" version="1.0" encoding="ISO-8859-1"/>
<!--Identity template to copy all content by default-->
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:choose>
<xsl:when test="/a/b[#flag='bar']">
<xsl:template match="/a/b/c"/>
</xsl:when>
</xsl:choose>
</xsl:stylesheet>
When I run this I get Error: Failed to compile stylesheet. 3 errors detected.
I'm looking for help (1) fixing the problems with the xsl code and (2) anything out there like jsfiddle for xsl that can debug/test fragements of xsl code.
You can't put a choose outside a template, but you don't need to - you can use predicates in match expressions so just declare your no-op template to match the elements you want to remove:
<xsl:template match="b[#flag='bar']/c" />
or more generally, if the parent of the c element might have various names
<xsl:template match="c[../#flag='bar']" />
or
<xsl:template match="*[#flag='bar']/c" />
Here is a snip-it of the XML:
<?xml version="1.0" encoding="iso-8859-1" ?>
<NetworkAppliance id="S123456">
<Group id="9">
<Probe id="1">
<Value>74.7</Value>
</Probe>
</NetworkAppliance>
I want to get the single point value of 74.7. There are many groups with unique ID's and many Probes under that group with unique ID's each with values.
I am looking for example XSLT code that can get me this one value. Here is what i have that does not work:
<?xml version="1.0" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="html" version="3.2" />
<xsl:template match="NetworkAppliance">
<xsl:apply-templates select="Group[#id='9']"/>
</xsl:template>
<xsl:template match="Group">
Temp: <xsl:value-of select="Probe[#id='1']/Value"/>
<br/>
</xsl:template>
</xsl:stylesheet>
Here is what worked for me in the end:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Edited by XMLSpy® -->
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<xsl:for-each select="NetworkAppliance/Group[#id=9]/Probe[#id=1]">
Value: <xsl:value-of select="Value" />
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Don't forget that you can do select several levels at once. Fixing your XML to:
<?xml version="1.0" encoding="iso-8859-1" ?>
<NetworkAppliance id="S123456">
<Group id="9">
<Probe id="1">
<Value>74.7</Value>
</Probe>
</Group>
</NetworkAppliance>
and using this stylesheet:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="html" version="3.2" />
<xsl:template match="/">
Temp: <xsl:value-of select="//Group[#id='9']/Probe[#id='1']/Value"/>
<br/>
</xsl:template>
</xsl:stylesheet>
we can pick out that one item you're interested in.
Points to note:
The // part of the expression means that the search for Group nodes takes place throughout the whole tree, finding Group nodes at whatever depth they're at.
The [#id='9'] part selects those Group nodes with id of 9
The Probe[#id='1'] part immediately after that selects those children of the Group nodes it found where the id is 1, and so on.
<xsl:value-of select="/NetworkAppliance/Group[#id=9]/Probe[#id=1]/Value"/>
XSLT is just one of the tools in the box, and nothing without XPath.
the xpath for value of a node is /node/text()
So
<xsl:value-of select="Probe[#id='1']/text()"/>
