Now, what if I want to replace all <p>-tags with <para>, and change
the namespace of all nodes to "foo"?
If the input is
<document>
<metaData>
<title>Title</title>
<publisher>Publisher</publisher>
</metaData>
<contentSection>
<p>text</p>
<headline level="2">Headline</headline>
<p>text</p>
<p>text</p>
<headline level="2">Section</headline>
<p>text</p>
<pagenum id="page2"/>
<p>text</p>
<headline level="3">Subsection</headline>
<p>text</p>
<headline level="2">Section</headline>
<p>text</p>
<p>text</p>
</contentSection>
</document>
then this stylesheet
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:mf="http://example.com/2009/mf";
xmlns="http://example.com/foo";
exclude-result-prefixes="xs mf">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:function name="mf:group" as="node()*">
<xsl:param name="nodes" as="node()*"/>
<xsl:param name="level" as="xs:integer"/>
<xsl:for-each-group select="$nodes"
group-starting-with="headline[(_at_)level = $level]">
<xsl:choose>
<xsl:when test="self::headline[(_at_)level = $level]">
<xsl:element name="level{$level}">
<xsl:element name="h{$level}">
<xsl:value-of select="."/>
</xsl:element>
<xsl:sequence select="mf:group(current-group() except .,
$level + 1)"/>
</xsl:element>
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="current-group()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:function>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="document">
<xsl:variable name="v1" xmlns="">
<headline level="1"><xsl:value-of
select="metaData/title"/></headline>
<xsl:copy-of select="contentSection/node()"/>
</xsl:variable>
<body>
<xsl:sequence select="mf:group($v1/node(), 1)"/>
</body>
</xsl:template>
<xsl:template match="p">
<para>
<xsl:apply-templates select="@* | node()"/>
</para>
</xsl:template>
</xsl:stylesheet>
creates the following output:
<body xmlns="http://example.com/foo";>
<level1>
<h1>Title</h1>
<para>text</para>
<level2>
<h2>Headline</h2>
<para>text</para>
<para>text</para>
</level2>
<level2>
<h2>Section</h2>
<para>text</para>
<pagenum xmlns="" id="page2"/>
<para>text</para>
<level3>
<h3>Subsection</h3>
<para>text</para>
</level3>
</level2>
<level2>
<h2>Section</h2>
<para>text</para>
<para>text</para>
</level2>
</level1>
</body>
