Set up a document called lookup.xml as follows:

<table>
<entry code="1" val="a"/>
<entry code="2" val="b"/>
...
</table>

Then you can do:

document('lookup.xml')/table/entry[@val=$val]/@code

For convenience, you can put the table inside the stylesheet - in
standard XSLT 1.0 you can reference the stylesheet as document(''), but
more efficiently you can put the lookup table in a variable and
reference it with the extension function xx:node-set().

For further efficiency with large lookup tables, learn about xsl:key and
the key function.
