Need to copy all elements of a parent element using xalan c++ (1.10)
Hi,
I need to copy all the child elements from the parent element to output xml using xalan c++ transform method. However, one of the child element is prefixed but does not have corresponding namespace.
What should I do in xslt so that all the children elements of parent element are copied to output xml file without caring the namespace. Altova XMLSpy does that but When I use xalan c++ 1.10 , it does not copy.
How I can achieve this using xalan c++ 1.10 ?
E.g.
Input XML file
============
<?xml version="1.0" encoding="UTF-8"?>
<SwInt:Request >
<SwInt:RequestHeader>
<SwInt1:Requestor>cn=requestor,o=pimxbebb,o=swift1</SwInt1:Requestor>
<SwInt:Responder>cn=responder,o=pimxus33,o=swift</SwInt:Responder>
<SwInt:RequestRef>xyz</SwInt:RequestRef>
</SwInt:RequestHeader>
</SwInt:Request>
XSLT file
======
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:Sw="urn:swift:snl:ns.Sw" xmlns:SwInt="urn:swift:snl:ns.SwInt" xmlns:SwSec="urn:swift:snl:ns.SwSec" >
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<xsl:copy-of select="/SwInt:Request/SwInt:RequestHeader"/>
</xsl:template>
</xsl:stylesheet>
Output Xml comes with
<?xml version="1.0" encoding="UTF-8"?>

A possibility - but I have not tested - is to coerce ParseSource
to create an instance of XSLTInputSource to use for the XML document
the Xerces-C WFXMLReader instead of the default IGXMLReader.
The WFXMLReader looks only for basic XML well-formedness and does not
do any namespace prefix mapping or namespace associated attribute
processing. The IGXMLReader by default knows about namespaces
and QNames.
Your failure is in the use of the Xerces-C IGXMLReader.
The XALAN project, as designed, conforms to the documented standards
and therefore uses the Xerces-C IGXMLReader.

This document does not conform to the namespaces recommendation, so you
cannot transform it using an XSLT processor.
I have no idea what behavior XML Spy implements, but the XSLT
recommendation is clear that the document must conform to the namespaces
recommendation:
http://www.w3.org/TR/xslt#section-Introduction
Is this really the exact document you're using, because I don't see how
Xerces-C would even parse it correctly, much less get any result from
Xalan-C.

If you can get a handle to specify properties for the underlying
Xerces XMLReaders, you might try setting the UsingNamespaces to false.
The default for Xalan when creating XMLReaders is "true".

Re: Need to copy all elements of a parent element using xalan c++

Posted by Steve Hathaway <sh...@e-z.net>.
The issue may be in the Xerces-C XMLReader when trying to construct a
nodeset.
I have not tried such LAX parsing of XML documents with Xerces-C callbacks.
When namespace prefixes are used, indicating qualified names, the
namespaces must be specified. This is part of wellformedness. The
presence of prefixes without qualifying names will cause the nodeset
generators to fail during namespace resolution, resulting in an empty
nodeset.
I have tried several methods trying to workaround your absence of
namespace qualified prefixes and failed. If you must have this capability,
you may need to coerce your source into a nodeset by other means and
supply your own document tree walker. - Good Luck!
Maybe someone else can shed some light on how to set specific features
for XMLReaders to accomplish what you want.

All namespace prefixes in your XML file should be namespace qualified.
<?xml version="1.0" encoding="UTF-8"?>
<SwInt:Request xmlns:SwInt="urn:swift:snl:ns.SwInt"
xmlns:SwInt1="urn:swift:snl:ns.SwInt1" >
<SwInt:RequestHeader>
<SwInt1:Requestor>cn=requestor,o=pimxbebb,o=swift1</SwInt1:Requestor>
<SwInt:Responder>cn=responder,o=pimxus33,o=swift</SwInt:Responder>
<SwInt:RequestRef>xyz</SwInt:RequestRef>
</SwInt:RequestHeader>
</SwInt:Request>
The following is an edit of your xslt file
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:SwInt="urn:swift:snl:ns.SwInt"
xmlns:SwInt1="urn:swift:snl:ns.SwInt1" >
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"
omit-xml-declaration="yes"/>
<xsl:template match="/">
<xsl:copy-of select="/SwInt:Request/SwInt:RequestHeader"/>
</xsl:template>
</xsl:stylesheet>
Producing the output file
<SwInt:RequestHeader xmlns:SwInt="urn:swift:snl:ns.SwInt"
xmlns:SwInt1="urn:swift:snl:ns.SwInt1">
<SwInt1:Requestor>cn=requestor,o=pimxbebb,o=swift1</SwInt1:Requestor>
<SwInt:Responder>cn=responder,o=pimxus33,o=swift</SwInt:Responder>
<SwInt:RequestRef>xyz</SwInt:RequestRef>
</SwInt:RequestHeader>
I am unclear on what you are actually trying to do:
You only need in the stylesheet the prefix declarations used in the
stylesheet. The xml documents need namespace declarations for the
prefixes they use.
