RE: Using a tree read with document() as a hash-table -- working solution

[Thorbjørn Ravn Andersen <TRA@xxxxxxxx>]

Thank you for your prompt reply! With these modifications the following code works:

<xsl:param name="packtypefile" select="'packtype.xml'" />

<!-- Load the packtypes from the external file -->
<xsl:variable name="packtypetree" select="document($packtypefile)"/>

[...]

<xsl:variable name="packinfopacktype" select="PACKINFO/@PACKTYPE"/>
<value><xsl:apply-templates select="$packtypetree//ROW[packcode=$packinfopacktype][1]" mode="hashlookup"/></value>

[...]
(PACKINFO/@PACKTYPE is the value I want to look up in the external file in a ROW/packnode, and I need the corresponding ROW/modultxt, which I get with

<xsl:template match="ROW" mode="hashlookup">
<xsl:message>HASH</xsl:message>
  <xsl:value-of select="modultxt"/>
<xsl:message>HSAH</xsl:message>
</xsl:template>

A quick test showed that the template-call could be avoided by using

    <value><xsl:value-of select="$packtypetree//ROW[packcode=$packinfopacktype][1]/modultxt"/></value>

instead.  This is just what I needed for a hash-lookup!

On a final note - would a key() make this faster?  I still have a bit of a problem understanding how it works.

Best regards,
