This however does work. If I hard-code the id in below it works, If I use a
variable as in above it does not work.
Any help would be appreciated.
since teh code is the same with teh exception that you'd replaced the
variable by '456' then I can only assume the variable doesn't have the
value think it should have (eg it has an extra space or two?)
try
<xsl:message>
[[<xsl:value-of select="$link-target"/>]]
</xsl:message>
and see what comes out.
A few unrelated observations
<xsl:variable name="link-target"
<xsl:value-of select="substring-after(./@linkends,'
')"/>
</xsl:variable>
don't do that here it's just ineffecient but as often comes up you can
get the wrong answer, a result tree fragment isn't needed here you can
just go
<xsl:variable
name="link-target"select="substring-after(./@linkends,' ')"/>
<xsl:when
test="name(//*[(_at_)id=$link-target])='grphprim'">
better to do //*[(_at_)id=$link-target]/self::grphrim
although // is very slow this is crying out to be done bia a key, see
other threads this week.
<xsl:variable name="parent_graphic"
select="//graphic[grphprim/@id=$link-target]"/>
<xsl:value-of select="$parent_graphic/@id">
The variable isn't needed, you could just inline the expression (and
again using a key may make orders of magnitude speedup
