[xsl] compare date value with 2 other ones

[Kristof Bernaert <kbernaert at 1eEurope dot be>]

Take the current date with this format: 05/04/2001

i have this xml with some news-blocks

<news>
<block startdate="03/04/2001" endddate="06/04/2001" id="1">news 1</block>
<block startdate="05/04/2001" endddate="10/04/2001" id="2">news 2</block>
</news>

I have an extern xml-file (current_date.xml, in same root of other *.xml)
that contains always current date like this
<current_date>05/04/2001</current_date>

now, in xsl i want only view the newsblocks where currentdate is between the
start- and enddate.

<xsl:for-each select="news/block[@startdate =>
document(current_date.xml)/current_date and @enddate =<
document(current_date.xml)/current_date]">
<xsl:apply-templates/>
</xsl:for-each>

of course, this isn't working, because:

How have i to handle the date ? to compare correctly the day, month and year
?

thx
