RE: [xsl] count selected nodes in for-each

Why "of course"?

Ahh -- given your example, it seems you want some logic like:

<xsl:for-each select="(...)">
...
</xsl:for-each>
<xsl:if test="(no nodes were handled by for-each)">
</xsl:if>

Then you could just do

<xsl:for-each 
select="document('../../released_xml/news_xml_en/newsticker.xml')/News/Block[@STARTDATE 
= '01']" >...</xsl:for-each>
<xsl:if 
test="not(document('../../released_xml/news_xml_en/newsticker.xml')/News/Block[@STARTDATE 
= '01'])">...</xsl:if>

or, more efficiently and clearer:

<xsl:variable name="blocks" 
select="document('../../released_xml/news_xml_en/newsticker.xml')/News/Block[@STARTDATE 
= '01']"/>
<xsl:for-each select="$blocks" >...</xsl:for-each>
<xsl:if test="not($blocks)">...</xsl:if>

But of course I'm still guessing a bit as to what you're trying to do...:-)

Cheers,
Wendell
