2 / div1
1 / div2
BTW, your solution doesn't select only div1, but it's the first node
of the node-set (because no more in the context of the ancestor axis
where it's the last node), so it's the one used to construct your
result.

I'm trying to build some links between a tag (table, graphic,
illustration)
and the referencing tag. So I have a <ref> tag that has an idref
attribute
that can reference these objects anywhere and these objects can
appear
directly under one of my division tags or they might be inside a
table or
code or some other lower level structure, ultimately in the link I
want to
build I need to know the containing division tag which is not always
the
immediate parent.
So I have a document that looks like:
<div1>
<p>Some text here</p>
<div2>
<p>More text <ref idref="t1'/></p>
<example>
<table id='t1'/>
</example>
</div2>
</div1>
I thought the following would work:
<template match="ref">
<xsl:variable name="parent"
select="id(@idref)/ancestor::div10 |
id(@idref)/ancestor::div9 |
id(@idref)/ancestor::div8 |
id(@idref)/ancestor::div7 |
id(@idref)/ancestor::div6 |
id(@idref)/ancestor::div5 |
id(@idref)/ancestor::div4 |
id(@idref)/ancestor::div3 |
id(@idref)/ancestor::div2 |
id(@idref)/ancestor::div1
"/>
<a href="{concat(generate-id($parent), '.html#', @idref)}">
Table <xsl:number level="any" from="div1" count="table"
format="1"/>
<xsl:text> </xsl:text>
</a>
</xsl:template>
Instead of finding the first <div2> tag this seems to always locate
the
highest ancestor in the tree and comes back with the <div1>. I even
changed
the order of the select for the variable to be high to low and low to
high
and nothing changed. I though maybe there might be an evaluation
order
going on.
I thought about adding a [1] to each item in the select for the
variable
but I don't think that changes anything, both the div2 and div1 are
the
first of that type. I think my only option is to split this select
out into
a chose statement which would force the order, is there another way
to do
this instead of:
<xsl:variable name="parent">
<xsl:choose>
<xsl:when test="id(@idref)/ancestor::div10">
<xsl:value-of select="id(@idref)/ancestor::div10"/>
</xsl:when>
....
</xsl:choose>
</xsl:variable>
thanks
