Processing a GPX file with xsl (probably a namespace issue) - xslt

This question looks like a duplicate of XPath query for GPX files with namespaces?, but I must be missing something because I can't seem to get a fairly simple style sheet to work. I have this input:
<?xml version="1.0" encoding="utf-8"?>
<gpx xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0" creator="Groundspeak Pocket Query" xsi:schemaLocation="http://www.topografix.com/GPX/1/0 http://www.topografix.com/GPX/1/0/gpx.xsd http://www.groundspeak.com/cache/1/0 http://www.groundspeak.com/cache/1/0/cache.xsd" xmlns="http://www.topografix.com/GPX/1/0">
<name>Ottawa Pocket Query</name>
<wpt lat="45.348517" lon="-75.825933">
<name>GC3HXAZ</name>
<desc>Craft maker box by FishDetective, Traditional Cache (2/2.5)</desc>
<url>http://www.geocaching.com/seek/cache_details.aspx?guid=e86ce3f5-9e75-48a6-b47e-9415101fc658</url>
<groundspeak:cache id="2893138" available="True" archived="False" xmlns:groundspeak="http://www.groundspeak.com/cache/1/0">
<groundspeak:name>Craft maker box</groundspeak:name>
<groundspeak:difficulty>2</groundspeak:difficulty>
<groundspeak:terrain>2.5</groundspeak:terrain>
</groundspeak:cache>
</wpt>
</gpx>
And a stylesheet that looks like this:
<?xml version="1.0"?>
<!-- -->
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:groundspeak="http://www.groundspeak.com/cache/1/0"
>
<xsl:output method="html"/>
<xsl:template match="/">
Cache names:
<xsl:apply-templates select="//wpt">
</xsl:apply-templates>
</xsl:template>
<xsl:template match="wpt">
<li><xsl:value-of select="groundspeak:cache/groundspeak:name"/></li>
</xsl:template>
</xsl:stylesheet>
And what I would expect is a list with one element on it, "Craft Maker Box", but what I get is an empty list.
What am I missing?

The default namespace is http://www.topografix.com/GPX/1/0. You should add that and use a prefix to match wpt.
Something like this: (untested)
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:groundspeak="http://www.groundspeak.com/cache/1/0"
xmlns:gpx="http://www.topografix.com/GPX/1/0"
>
<xsl:output method="html"/>
<xsl:template match="/">
Cache names:
<xsl:apply-templates select="//gpx:wpt">
</xsl:apply-templates>
</xsl:template>
<xsl:template match="gpx:wpt">
<li><xsl:value-of select="groundspeak:cache/groundspeak:name"/></li>
</xsl:template>
</xsl:stylesheet>

It is indeed a namespace issue. You have
xmlns="http://www.topografix.com/GPX/1/0"
in the XML so unprefixed element names are in this namespace. You need to bind the same uri to a prefix in your stylesheet, e.g.
xmlns:g="http://www.topografix.com/GPX/1/0"
and then use g:wpt in the match and select expressions.

How to add namespace and xsi to the Incoming XML with no namespace

I have requirement where I have to add Namespace and xsi to the
element from the source xml with No Namespace.
In Source XML I am just getting the Nodes and there is No namespace
and another program needs BizTalk to add Namespace and XSI to the XML for its processing.
I tried:
Used add namespace pipeline component. (It just added
namespace and not the xsi bits)
Used Map for putting up the desired format and yes no luck as got
just the namespace.
Need your help around this.
My source XML is like
<?xml version="1.0" encoding="UTF-16"?>
<Document>
<CstmrPmtStsRpt>
<GrpHdr>
<MsgId></MsgId>
<CreDtTm></CreDtTm>
<InitgPty>
<Id>
<OrgId>
<BICOrBEI></BICOrBEI>
</OrgId>
</Id>
</InitgPty>
</GrpHdr>
<OrgnlGrpInfAndSts>
<OrgnlMsgId></OrgnlMsgId>
<OrgnlMsgNmId></OrgnlMsgNmId>
<OrgnlNbOfTxs></OrgnlNbOfTxs>
<OrgnlCtrlSum></OrgnlCtrlSum>
<GrpSts>ACCP</GrpSts>
</OrgnlGrpInfAndSts>
</CstmrPmtStsRpt>
</Document>
My Required format is as below:
<?xml version="1.0" encoding="UTF-8"?>
<Document xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="MyNamespace">
<CstmrPmtStsRpt>
<GrpHdr>
<MsgId></MsgId>
<CreDtTm></CreDtTm>
<InitgPty>
<Id>
<OrgId>
<BICOrBEI></BICOrBEI>
</OrgId>
</Id>
</InitgPty>
</GrpHdr>
<OrgnlGrpInfAndSts>
<OrgnlMsgId></OrgnlMsgId>
<OrgnlMsgNmId></OrgnlMsgNmId>
<OrgnlNbOfTxs></OrgnlNbOfTxs>
<OrgnlCtrlSum></OrgnlCtrlSum>
<GrpSts>ACCP</GrpSts>
</OrgnlGrpInfAndSts>
</CstmrPmtStsRpt>
</Document>
Use the namespace attribute of xsl:element like this:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="*">
<xsl:element name="{local-name()}" namespace="MyNamespace">
<xsl:namespace name="xsi" select="'http://www.w3.org/2001/XMLSchema-instance'"/>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Edit: Since you need to work with XSLT-1.0. Use following stylesheet:
<?xml version="1.0" encoding="UTF-16"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/Document">
<Document xmlns="MyNamespace"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<xsl:apply-templates/>
</Document>
</xsl:template>
<xsl:template match="*">
<xsl:element name="{local-name()}" namespace="MyNamespace">
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Note, that you need to know your rootnode's name for this (in this case Document).
BizTalk Answer:
First, it's a good thing the incoming document has no namespace. Xml Namespaces are far, far, far more trouble than they're worth and should be avoided/removed whenever possible.
Second the output format is not valid Xml. "MyNamespace" is not a valid URI and can't be used for a Namespace. If this is what they are asking for, they need to fix that first.
But, if you must, your process should not be "add a namespace". What you're really doing is Transforming from SysA's Document to SysB's Document. For that, use a Map. You will use to practially identical Schemas, one with and one without the Target Namespace.
The Mapper will handle xsi for you as well, if it's needed.

Extract text inside cdata tag using XSLT

I have the following XML with a cdata tag that I would like to extract the text from?
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<cus:TestData xmlns:cus="http://test.namespace.com/data">
<![CDATA[testValue]]></cus:TestData >
How can I achieve this in XSLT?
I was briefly trying with the following
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
"<xsl:value-of select="/*/Name"/>"
</xsl:template>
</xsl:stylesheet>
But it doesn't seem to be working
Also the XML doesn't also have the same prefix or namespace, it changes
This is not really an issue with CData. Your XSLT is currently looking for an element called Name, under the root element, which does not exist in your XML. If your XML source is the one you are actually using, you can just do this...
<xsl:value-of select="/*"/>
But supposing your XML looked like this...
<cus:TestData xmlns:cus="http://test.namespace.com/data">
<cus:Name><![CDATA[testValue]]></cus:Name>
</cus:TestData>
Then, you would need to account for the namespace in your XSLT, as Name is in a namespace in your XML, but your XSLT is currently looking for a Name element in no namespace.
Something like this would do:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:c="http://test.namespace.com/data">
<xsl:output method="text"/>
<xsl:template match="/">
"<xsl:value-of select="/*/c:Name"/>"
</xsl:template>
</xsl:stylesheet>
Note, the prefixes don't need to match, but the namespace URI does.
If the namespace URI could actually vary, you could do something like this instead...
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
"<xsl:value-of select="/*/*[local-name() = 'Name']"/>"
</xsl:template>
</xsl:stylesheet>

XPath 3.0 Serialize without Namespaces in Scope

While answering this question, it occurred to me that I know how to use the XSLT 3.0 (XPath 3.0) serialize() function, but that I do not know how to avoid serialization of namespaces that are in scope. Here is a minimal example:
XML Input
<?xml version="1.0" encoding="UTF-8" ?>
<ci:cichlids xmlns:ci="http://www.cichlids.com">
<cichlid id="1">
<name>Zeus</name>
<color>gold</color>
<teeth>molariform</teeth>
<breeding-type>lekking</breeding-type>
</cichlid>
</ci:cichlids>
XSLT 3.0 Stylesheet
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:output="http://www.w3.org/2010/xslt-xquery-serialization"
xmlns:ci="http://www.cichlids.com">
<xsl:output method="xml" encoding="UTF-8" indent="yes" />
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/ci:cichlids/cichlid">
<xsl:variable name="serial-params">
<output:serialization-parameters>
<output:omit-xml-declaration value="yes"/>
</output:serialization-parameters>
</xsl:variable>
<xsl:value-of select="serialize(., $serial-params/*)"/>
</xsl:template>
</xsl:stylesheet>
Actual Output
<?xml version="1.0" encoding="UTF-8"?>
<ci:cichlids xmlns:ci="http://www.cichlids.com">
<cichlid xmlns:ci="http://www.cichlids.com" id="1">
<name>Zeus</name>
<color>gold</color>
<teeth>molariform</teeth>
<breeding-type>lekking</breeding-type>
</cichlid>
</ci:cichlids>
The serialization process included the namespace declaration that is in scope for the cichlid element, although it is not used on this element. I would like to remove this declaration and make the output look like
Expected Output
<?xml version="1.0" encoding="UTF-8"?>
<ci:cichlids xmlns:ci="http://www.cichlids.com">
<cichlid id="1">
<name>Zeus</name>
<color>gold</color>
<teeth>molariform</teeth>
<breeding-type>lekking</breeding-type>
</cichlid>
</ci:cichlids>
I know how to modify the cichlid element, removing the namespaces in scope, and serialize this modified element instead. But this seems a rather cumbersome solution. My question is:
What is a canonical way to serialize an XML element using the serialize() function without also serializing unused namespace declarations that are in scope?
Testing with Saxon-EE 9.6.0.7 from within Oxygen.
Serialization will always give you a faithful representation of the data model that you are serializing. If you want to modify the data model, that's called transformation. Run a transformation to remove the unwanted namespaces, then serialize the result.
Michael Kay already gave the correct answer and I have accepted it. This is just to flesh out his comments. By
Run a transformation to remove the unwanted namespaces, then serialize the result.
he means applying a transformation like the following before calling serialize():

XSLT not matching element - namespace declarations

I'm sure this is a very simple fix, but I'm stumped. I've got input XML with the following root element, and repeating child elements:
<modsCollection
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.loc.gov/mods/v3"
xsi:schemaLocation="
http://www.loc.gov/mods/v3
http://www.loc.gov/standards/mods/v3/mods-3-4.xsd">
<mods version="3.4">
...
I've got an XSLT sheet with the following to match each <mods> node, and kick it out as a separate file named by an <identifier type="local"> element.
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.loc.gov/mods/v3">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/modsCollection">
<xsl:for-each select="mods">
<xsl:variable name="filename"
select="concat(normalize-space(
identifier[#type='local']),
'.xml')" />
<xsl:result-document href="{$filename}">
<xsl:copy-of select="."></xsl:copy-of>
</xsl:result-document>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
This works if the XML input does not have the xmlns:xsi, xmlns, or xsi:schemaLoaction attributes in the root element. So, for example, it works on the following:
<modsCollection>
<mods version="3.4">
...
I know that some of our MODS files have had the prefix included but I'm unclear why this won't work without the prefix if our XSLT matching is not looking for the prefix. Any thoughts or advice would be greatly appreciated.
<xsl:template match="/modsCollection">
matches modsCollection in no namespace. You want
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.loc.gov/mods/v3"
xmlns:m="http://www.loc.gov/mods/v3">
then
<xsl:template match="/m:modsCollection">
To match modsCollection in the mods namespace, and similarly use the m: prefix in all xslt patterns and xpath expressions in the stylesheet.

XSLT transform error

I have the following xml:
<RootNode xmlns="http://someurl/path/path/path">
<Child1>
<GrandChild1>Value</GrandChild1>
<!-- Lots more elements in here-->
</Child1>
</RootNode>
I have the following xslt:
<xsl:stylesheet version="1.0" xmlns="http://someurl/path/path/path" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<NewRootNode xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NewChild1>
<xsl:for-each select="RootNode/Child1">
<NewNodeNameHere>
<xsl:value-of select="GrandChild1"/>
</NewNodeNameHere>
<!-- lots of value-of tags in here -->
</xsl:for-each>
</NewChild1>
</NewRootNode >
</xsl:template>
</xsl:stylesheet>
The problem: this is the my result:
<?xml version="1.0" encoding="utf-8"?>
<NewRootNode xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NewChild1 />
</NewRootNode>
I am expecting to see:
<?xml version="1.0" encoding="utf-8"?>
<NewRootNode xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NewChild1>
<NewNodeNameHere>Value</NewNodeNameHere>
<!-- Other new elements with values from the xml file -->
</NewChild1>
</NewRootNode>
I am missing of the information inside of NewChild1 that should be there.
I think my for-each select is correct, so the only thing I can think of is that there is a problem with the namespace in the Xml and the namespace in the xslt. Can anybody see what I'm doing wrong?
The problem is caused by the namespaces.
Since the xml defines xmlns="http://someurl/path/path/path", it is not in the default namespace anymore.
You can define that namespace with an name like xmlns:ns="http://someurl/path/path/path" in the xsl, and then use that name in the XPath expression.
The following works for me:
<xsl:stylesheet version="1.0" xmlns:ns="http://someurl/path/path/path" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<NewRootNode xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NewChild1>
<xsl:for-each select="ns:RootNode/ns:Child1">
<NewNodeNameHere>
<xsl:value-of select="ns:GrandChild1"/>
</NewNodeNameHere>
<!-- lots of value-of tags in here -->
</xsl:for-each>
</NewChild1>
</NewRootNode >
</xsl:template>
</xsl:stylesheet>
The stylesheet namespace should be http://www.w3.org/1999/XSL/Transform instead of http://someurl/path/path/path.
Also, since the input XML uses a namespace all your XPath expressions should be namespace-qualified:
<xsl:template match="/" xmlns:ns1="http://someurl/path/path/path">
<NewRootNode xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<NewChild1>
<xsl:for-each select="ns1:RootNode/ns1:Child1">
<NewNodeNameHere>
<xsl:value-of select="ns1:GrandChild1"/>
</NewNodeNameHere>
<!-- lots of value-of tags in here -->
</xsl:for-each>
</NewChild1>
</NewRootNode>
</xsl:template>
