I'm quite new to XSLT.
This is the problem I'm trying to solve for hours now:
I auto-generate a table of contents for a xml document which works great so far. However I'd like to replace a placeholder tag in my source xml with that just generated toc code. So the output should include the whole document with replaced placeholder-toc-tag with the auto-generated toc xml.
This is what I've tried:
Let's say I have my placeholderTag anywhere in the document and want to replace this/those. I thought that I could loop through all nodes by node() and check if the node name equals my placeholder tag:
<xsl:template match="node()">
<xsl:choose>
<xsl:when test="divGen">
<!-- apply other template to generate toc-->
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="node()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
However the if statement won't match like this.
edit: Ok, here's the source document (TEI coded - TEI namespace removed):
<TEI>
<teiHeader>
<fileDesc>
<titleStmt>
<title>Title</title>
</titleStmt>
<publicationStmt>
<p>Publication information</p>
</publicationStmt>
<sourceDesc>
<p>Information about the source</p>
</sourceDesc>
</fileDesc>
</teiHeader>
<text>
<front>
<titlePage>
<byline>title page details</byline>
</titlePage>
</front>
<body>
<divGen type="toc"/>
<div type="part">
<div type="section">
<head>heading1</head>
</div>
<div type="section">
<head>heading2</head>
</div>
</div>
<div type="part">
<div type="section">
<head>heading3</head>
</div>
<div type="section">
<head>heading4</head>
</div>
<div type="section">
<head>heading5</head>
</div>
</div>
</body>
<back> </back>
</text>
I'd like to auto-generate the toc from the head values and replace the divGen tag by the auto-produced toc code. However please notice that the divGen tag can be anywhere in the document but not outside of body.
Any ideas?

Good question, +1.
Here is a complete transformation (with mock TOC generation to be replaced by real one) that shows how to do this:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="vTOC">
<xsl:apply-templates mode="TOC"/>
<mockTOC>
<xsl:comment>The real TOC generated here</xsl:comment>
</mockTOC>
</xsl:variable>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
<xsl:template match="divGen[@type='toc']">
<xsl:copy-of select="$vTOC"/>
</xsl:template>
<xsl:template match="text()" mode="TOC"/>
</xsl:stylesheet>
when this transformation is applied on the provided XML document:
<TEI>
<teiHeader>
<fileDesc>
<titleStmt>
<title>Title</title>
</titleStmt>
<publicationStmt>
<p>Publication information</p>
</publicationStmt>
<sourceDesc>
<p>Information about the source</p>
</sourceDesc>
</fileDesc>
</teiHeader>
<text>
<front>
<titlePage>
<byline>title page details</byline>
</titlePage>
</front>
<body>
<divGen type="toc"/>
<div type="part">
<div type="section">
<head>heading1</head>
</div>
<div type="section">
<head>heading2</head>
</div>
</div>
<div type="part">
<div type="section">
<head>heading3</head>
</div>
<div type="section">
<head>heading4</head>
</div>
<div type="section">
<head>heading5</head>
</div>
</div>
</body>
<back>
</back>
</text>
</TEI>
the correct, wanted output is produced, in which any occurences of <divGen type="toc"/> are replaced by the generated TOC:
<TEI>
<teiHeader>
<fileDesc>
<titleStmt>
<title>Title</title>
</titleStmt>
<publicationStmt>
<p>Publication information</p>
</publicationStmt>
<sourceDesc>
<p>Information about the source</p>
</sourceDesc>
</fileDesc>
</teiHeader>
<text>
<front>
<titlePage>
<byline>title page details</byline>
</titlePage>
</front>
<body>
<mockTOC><!--The real TOC generated here--></mockTOC>
<div type="part">
<div type="section">
<head>heading1</head>
</div>
<div type="section">
<head>heading2</head>
</div>
</div>
<div type="part">
<div type="section">
<head>heading3</head>
</div>
<div type="section">
<head>heading4</head>
</div>
<div type="section">
<head>heading5</head>
</div>
</div>
</body>
<back/>
</text>
</TEI>
Explanation: Use of modes to pre-generate the TOC in a variable, then overriding the identity rule for any TOC placeholder.
