[xsl] XSL String Mapping Problem.

["Jos van Roosmalen" <jos.v.roosmalen@xxxxxxxxx>]

Hello,

I am looking for a very nice mapper  "Design Pattern".

I used the XML/XSL snippet below. However the "@key eq ." seems not to work.

If I introduce a variable it works fine:

    <xsl:variable name="var" select="."/>
    <xsl:value-of select="$map[@key eq $var]/@val"/>

Questions:

1. How to get this mapper working without variable?
2. What is the the 'defacto XPath standard' for mapping  a list
hardcoded keys to hardcoded values?

Thanks, Jos
