select document xsl
Hallo,
my recursive template to sort does not work fine. There is one problem to
test if there are following pers_data nodes which have some attribute in a
nodeset.
Is there a possiblity to ask with xpath: are there following-sibling nodes
named pers_data in a variable ?

<xsl:if
test="not(following-sibling::pers_data[document(./url/@path)/pers_data/*[name()=
$category] = $element])">

I would be happy if someone can give me help. The solution must be in xslt1.
Many thanks
Markus

<xsl:template match="node[attribute::type='interviewee']">
  <xsl:call-template name="take_category">
    <xsl:with-param name="pos_category" select="1" />

<xsl:template name="take_category">
<xsl:param name="pos_category" />
<xsl:param name="nodeset" />
<!-- how many categories are given -->
<xsl:param name="total_category" select="count(...)" />
<!-- take the first, second,.. category -->

<!-- take a element of the category -->
