 Hi, sorry it's me again. No need to apologize! Absolutely ... the designers of XSLT provided for just this. I frist thought about declaring an ID attribute for any chapter but I don't know if I can point to that ID by html hrefs. Yes, you could do that, but it is not necessary in XSLT. Every node in every tree created for an XSLT process (all source trees and the stylesheet tree) is assigned a generated unique identifier. This identifier is an opaque value that is used in its entirety and is defined by the processor in any fashion it wishes, provided that the identifier lexically matches an XML NCName. NCNames can, therefore, be used in HTML anchors as names and hrefs. You ask the processor for a node's generated identifier using the function generate-id(nodeAddress) and every time you ask for that node's identifier in a given run of a stylesheet, you get the same value back. It may or may not be the same value the next time you run the stylesheet, so you cannot rely on any persistence so you cannot expect an identifier generated for a node in one run will be the same in the next run. You take advantage of these generated identifiers to synthesize ID/IDREF relationships, not only where there are no ID values available, but I have learned through experience it is safest to use generated identifiers even for nodes that have ID values (this protects from ambiguities when dealing with multiple source trees with ID values in each). When you process your chapter table of contents, you utilize the chapter's generated identifier in the href= attribute. To ensure there is something to point to when you process your chapter, you utilize the chapter's generated identifier in the name= attribute. The resulting file has resolved HTML hyperlinks from your TOC to your body. <!--TOC-->
<xsl:for-each select="b:Book/b:chapters/iese.Chapter:Chapter">
<li>
<a href="{generate-id(.)}">
<xsl:value-of select="iese.Chapter:heading"/>
</a>
</li>
</xsl:for-each>
...
<!--Body processing-->
<xsl:for-each select="b:Book/b:chapters/iese.Chapter:Chapter">
<h3>
<a name="{generate-id(.)}">
<xsl:value-of select="iese.Chapter:heading"/>
</a>
</h3>
<!--rest of chapter processing-->
</xsl:for-each>I hope this helps. ............................. Ken p.s.
