and the error I get is "Reference to variable or parameter 'mixed' must
evaluate to a node list."
------------------------------------------------------------------------
My bad. Please accept my apologies. As David C. and Wendell both caught me
on, I had used an XSLT 2.0 processor for an XSLT 1.0 project and had
inadvertently rolled in a couple XSLT 2.0 features that your processor is
now catching. Here's a pair of stylesheets that correct the problems:
As you may recall, my method (in among all the madness) was to first turn
this into a grouping problem and then to solve the grouping problem. So,
this first stylesheet turns your mixed content problem into a grouping
problem by turning each child node of the paragraph except for the
blockquote into its own paragraph element.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<x>
<xsl:apply-templates/>
</x>
</xsl:template>
<xsl:template match="paragraph">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="paragraph/text()">
<p num="{../@num}"
group="{count(preceding-sibling::blockquote)}"><xsl:value-of
select="."/></p>
</xsl:template>
<xsl:template match="blockquote">
<blockquote><xsl:apply-templates/></blockquote>
</xsl:template>
<xsl:template match="italic">
<p num="{../@num}"
group="{count(preceding-sibling::blockquote)}"><span
style="font-style:italic"><xsl:apply-templates/></span></p>
</xsl:template>
</xsl:stylesheet>
When I run it with Xalan-J 2.4.1 (an XSLT 1.0 processor), I get:
<?xml version="1.0" encoding="UTF-8"?>
<x>
<p group="0" num="1">Yadda Yadda Yadda </p>
<p group="0" num="1">
<span style="font-style:italic">Italic Yadda</span></p>
<p group="0" num="1"> Yadda: </p>
<blockquote>Blah Blah Blah Blah</blockquote>
<p group="1" num="1"> Yackity Yack Yack</p>
</x>
This second stylesheet solves the grouping problem:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="x">
<html>
<head>
<title>Paragraph Chunking Test</title>
</head>
<body>
<xsl:for-each select="p[not(preceding-sibling::*[1]/self::p)]">
<xsl:variable name="group" select="@group"/>
<p>
<xsl:for-each select="../p[@group=$group]">
<xsl:apply-templates/>
</xsl:for-each>
</p>
<xsl:apply-templates select="following-sibling::blockquote"/>
</xsl:for-each>
</body>
</html>
</xsl:template>
<xsl:template match="p"/>
<xsl:template match="blockquote">
<xsl:copy-of select="."/>
</xsl:template>
<xsl:template match="span">
<xsl:copy-of select="."/>
</xsl:template>
</xsl:stylesheet>
Applied to the result of the first stylesheet, it produces (again with
Xalan-J 2.4.1) the following output:
<html>
<head>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Paragraph Chunking Test</title>
</head>
<body>
<p>Yadda Yadda Yadda <span style="font-style:italic">Italic
Yadda</span> Yadda: </p>
<blockquote>Blah Blah Blah Blah</blockquote>
<p> Yackity Yack Yack</p>
</body>
</html>
Thank you for your patience. Also, thanks to Wendell and David C. for
their constant instruction.
