Re: Problem with XPath in my XSL

    <xsl:variable name="NZ" select="nutzungszone"></xsl:variable>

so $NZ is a node set of nutzungszone elements.

 $NZ = '' 


is true if there is some item in the node set $NZ that has string value
"" this will not be the case if $NZ is empty.

Also it's best never to use != in conjunction with node sets (it almost
never means what you want).

I suspect that you really mean to test whether there are any elements
rather than test if any of them have empty string value in which case
your tests should be (for example)

    <xsl:when test="$geb  and not($stock) and not($NZ) and not($raum)">
