Thanx to both of you, both ways work.
Askild's and my expression are conceptionally equal. They way it works is simple: [expression] are called predicates. node[expression] is only selected if the predicate evaluates to true. This is the case if $client matches client for the first part of the expression when the projects are filtered. And the second part evaluates to true if $client is "empty". Askild's expression tests exactly for empty string, I use the normalize-space() for the case $client contains whitespaces.
I read somewhere, that it's possible to change the value as long as it has not been set...bit maybe i got something wrong.
Sounds like a paradoxon :) If you think of it like Java's final, that's false.
<xsl:variable name="test"/>
...
<xsl:choose>
<xsl:when test="expression">
<xsl:variable name="test" select="test"/>
</xsl:when>
<xsl:otherwise>
<xsl:variable name="test" select="test2"/>
</xsl:otherwise>
</xsl:choose>will not work.
