RE: [xsl] key() and document() - scoping problem?

["Geert Josten" <geert.josten@xxxxxxxxxxx>]

If you want the span elements to repeat by the number of option elements
and not just one like here:

You could do something like the following in XSLT 1.0 , but it is not
very nice:

Top-level:

<xsl:variable name="this-document" select="/" />

<xsl:template ...>
  <span class="x">
    <xsl:value-of select="count(key('key2_1', 'general'))" />
  </span>
  <xsl:for-each select="document(string($options))/options/option">
    <xsl:variable name="$option" select="." />
    <span class="y">
      <xsl:for-each select="$this-document">
        <xsl:value-of select="count(key('key2_1', $option))" />
      </xsl:for-each>
    </span>
  </xsl:for-each>
</xsl:template>

I put the option element in a variable to show how its value can be used
as a parameter of the 2nd key function

HTH!
