Thanks for the answer, it works partly. I forgot to tell that the code in the structure file can also be longer: for example:


There should be a longest match. So the following element should match the second field:
<org code="PYTT/030/040/050/060">

I think the expresion will be so complex that it will be quicker to do the xsl-for each statement.

I got a problem with defining my keys right. I got a separate XML file where I want to lookup things according to a code. The XML structure file looks as follows:


In the main XML file the codes contain more numbers for example:
<org code="PYTT/010/030/040"/>

I want to access the first file using keys. I already managed to access using a for-each and this works fine but too slow.

Define key

<xsl:key name="field" match="field" use="code"/>

The code looks like this:
<xsl:variable name="code" select="@code"/>
<xsl:for-each select="document($structure-doc)">
<xsl:for-each select="fields/field[starts-with($code, code)] ">

Here use

<xsl:for-each select="key('field', substring($code, 0, 9))">


<xsl:for-each select="key('field', concat(substring-before($code, '/'), '/', substring-before(substring-after($code, '/'), '/')))">

I.e. you can't use starts-with, you use the equality operator for key lookups.
