Sorry about that. The xml would look like this:

<entry>
  <CrossReference xrefLabel="ADDF32 RaH, #16FHi, RbH" href="#ADDF32RaH16FRbH"/>
  <br Placement="line"/>
<CrossReference xrefLabel="ADDF32 RaH, RbH, #16FHi" href="#ADDF32RaHRbH16F"/>
</entry>
   In this case, the entry element contains two CrossReference elements. The first CrossReference element, its' href attribute does not have any element that has a Target attribute with that value.

I would expect to see:

No target for:
ADDF32RaH16FRbH

Does this make more sense now?

You code does make sense but you have not shown a complete sample where you don't get a result.

For instance when I take your stylesheet

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

<xsl:key name="target_ref_key" match="*[@Target]" use="@Target" />

<xsl:template match="CrossReference">

<xsl:variable name="unhash_name" select="substring-after(@href, '#')"/> <xsl:variable name="matched" select="key('target_ref_key', $unhash_name)"/> <xsl:if test="not($matched)"> No target for: <xsl:value-of select="$unhash_name"/> </xsl:if>

</xsl:template>

</xsl:stylesheet>

and create a minimal input sample _with_ an element having a Target attribute, as in

<root> <entry> <CrossReference xrefLabel="ADDF32 RaH, #16FHi, RbH" href="#ADDF32RaH16FRbH"/> <br Placement="line"/> <CrossReference xrefLabel="ADDF32 RaH, RbH, #16FHi" href="#ADDF32RaHRbH16F"/> </entry> <foo Target="ADDF32RaHRbH16F"/> </root>

then Saxon 6.5 outputs

    No target for:
    ADDF32RaH16FRbH

So something is different in your samples, you will need to post minimal but complete samples allowing us to reproduce the problem.
