RE: Can't get id() and key() to work

Hi,

Assuming you have the key set up correctly you can simply match the 'image' tag
from you source XML (example source would help). The source XML's image tag has
the unique ID. For example:

<xsl:template match="image">
  <xsl:for-each select="$infodoc">
    <xsl:message>info2=<xsl:value-of select="$path-key"/></xsl:message>
    <xsl:message>info3=<xsl:value-of select="key('imgInfoKey',
$path-key)/@width"/></xsl:message>
    <xsl:message>info4=<xsl:value-of select="key('imgInfoKey',
$path-key)/@height"/></xsl:message>
  </xsl:for-each>
</xsl:template>

I try to avoid extensions. Do you really need them? If you can do without, then
you need to get into the context of the document you need information from. Then
use the key to find the nodeset and get the value you want from there. You
cannot store the value of this nodeset in a variable. You need to use the key
each time.

Does this help?

best,
