and now my 2nd (and hopefully last) question for today ...

I have to write an xsl file, which calculates the maximal depth of an input xml file.
<abc>
    <cde>
        <efg/>
        <asd/>
    </cde>
    <aaa/>
</abc>
=> maxdepth = 3 ....

I think I have to use a "for each" with sorting and increment a variable, but I don't know how to do this (you see, I'm a big noob @ xml/xsl :( ... )

Forget about incrementing a variable, there is no such thing in XSLT. Sort all elements by number of ancestors and take the first one. <xsl:template match="/"> <xsl:for-each select="//*"> <xsl:sort select="count(ancestor::*)" data-type="number" order="descending"/> <xsl:if test="position() = 1"> <xsl:value-of select="count(ancestor::*)+1"/> </xsl:if> </xsl:for-each> </xsl:template>
