Subject: [xml-dev] Saxon and Sun
Serializer problems?
Hi Folks
I am using saxonb9-1-0-2j
When I serialize through a sax
pipeline which is handling ContentHandler and LexicalHandler events and I run through
a saxon XSLT transformer, my DOCTYPE dissapears unless I use the the saxon
serializer. When I run through a sax pipeline that just parses and
serializes, my DOCTYPE dissapears unless I use the Sun provided serializer.
This causes problems for generalizing
the code.
Here is my XSL and serializer setup
code below:
**************** XSL
<xsl:stylesheet version='2.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
<!--
conrefTargets.xsl
Make the link target
text for the navigation link targets. This expects topic input.
-->
<xsl:output
method="xml" encoding="UTF-8" />
<xsl:param
name='parm1' select="'Parm1 Default Value'"></xsl:param>
<!-- Define a
newline character -->
<xsl:variable
name='newline'>
<xsl:text>
</xsl:text>
</xsl:variable>
<xsl:variable
name='topicId' select='/topic/@id'></xsl:variable>
<!--
*********************************************************************************
The outer
target node list.
*********************************************************************************
-->
<!-- <xsl:template
match="*|@*|text()"> -->
<xsl:template
match='node()|@*'>
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template
match="p">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
<p
class="- topic/p "><xref class="- topic/xref "
href=""{$parm1}"" >Hello Link</xref></p>
</xsl:template>
</xsl:stylesheet>
