Getting Xerces to accept copy-of parameters

[Patrik Carlsson]

I have a problem using Xerces with a template for
a generic page-header getting a sub-tree as argument.
The same stylesheet is working flawlessly in IE and
Mozilla, though it would be nice to have a result-file
to work with too.

Here is an example (xerces only get a collapsed string through),
any suggestions or current bug-reports are welcome.

My "paramtest. xml" :

<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="sendparam .xsl"?>
<rootnode>
<treenode>
<organization>T he Apache Software Foundation</organization>
<street>1901 Munsey Drive</street>
<address>Fore st Hill, MD 21050-2747</address>
<country>U.S. A</country>
</treenode>
<othernode>
othernode
</othernode>
</rootnode>

The stylesheet "sendparam. xsl" sending a node as parameter :

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes"
doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dt d"
doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN"
encoding="ISO-8859-1" />

<xsl:include href="getparam. xsl"/>

<xsl:template match="rootnode ">

<xsl:variable name="treecopy" >
<xsl:copy-of select="treenod e"/>
</xsl:variable>

<xsl:call-template name="testtempl ate">
<xsl:with-param name="paramtree " select="$treeco py"/>
</xsl:call-template>

</xsl:template>
</xsl:stylesheet>

A generic stylesheet "getparam.x sl" using the parameter :

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes"
encoding="ISO-8859-1" />

<xsl:template name="testtempl ate">
<xsl:param name="paramtree ">no recipent</xsl:param>
<xsl:for-each select="$paramt ree/treenode/*">
<b>
<xsl:value-of select="."/>
</b>
<br/>
</xsl:for-each>
</xsl:template>

</xsl:stylesheet>

You do mean you're using Xalan, right? Xerces is an XML parser, not
an XSLT processor.

....
The stylesheet "sendparam. xsl" sending a node as parameter :

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes"
doctype-system="http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dt d"
doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN"
encoding="ISO-8859-1" />

<xsl:include href="getparam. xsl"/>

<xsl:template match="rootnode ">

<xsl:variable name="treecopy" >
<xsl:copy-of select="treenod e"/>
</xsl:variable>

....

This variable is a result tree fragment, which has limitations in XSLT
1.0.
<xsl:call-template name="testtempl ate">
<xsl:with-param name="paramtree " select="$treeco py"/>
</xsl:call-template>

</xsl:template>
</xsl:stylesheet>

A generic stylesheet "getparam.x sl" using the parameter :

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes"
encoding="ISO-8859-1" />

<xsl:template name="testtempl ate">
<xsl:param name="paramtree ">no recipent</xsl:param>
<xsl:for-each select="$paramt ree/treenode/*">
<b>
<xsl:value-of select="."/>
</b>
<br/>
</xsl:for-each>
</xsl:template>

</xsl:stylesheet>

You are trying to use a result tree fragment as a node-set, which is
not allowed in XSLT 1.0. MSXSL 3.0 allows this, but 4.0 does not. I
don't know why Mozilla allows this, but that's a bug. Xalan is
correctly rejecting your stylesheet.

One way around this is to use a processor-specific extension to
convert a result tree fragment. Another choice is to use the EXSLT
node-set extension, which is more portable.

Thank's for the help,
Knowing the difference between node-sets and tree-fragments helped a lot.
Since my application was simple just sending the node without using
a variable solved my problem:

<xsl:with-param name="paramtree " select="/rootnode/treenode"/>

Then the parameter can be traversed as I wished

<xsl:for-each select="$paramt ree/*">
<b><xsl:value-of select="."/></b><br/>
</xsl:for-each>

Cheers
