Thanks to David and Michael! That works :-)

But if I want to use the value of the string for other operations I
have to declare a global variable, right? I want to declare the
variable in an external variables.xsl file. My idea was to create the
variables.xsl => xsl:apply-templates which points to the source
document => count the lines => use the resulting variable in my
stylesheet document. So far my idea :-)

Is it possible to match the node of an external document like
<xsl:template match="document('variables.xsl')/block"> or something like
this?

The variables.xsl file looks like this:

<xsl:template match="block">
<xsl:variable name="countlines">
<xsl:apply-templates/>
<xsl:value-of select="string-length(.) -
string-length(translate(.,'&#xA;', ''))"/>
</xsl:variable>
</xsl:template>

Thanks so much for your patience :-) I am just waiting for Michael
Kays two books about XPath 2.0 and XSLT 2.0 for helping me with the
theme.
