Hi jeni,
Thank you, I think I know a little more about how sort works...
You're currently using xsl:for-each to iterate over the unique dates;
why not sort them in the same way as you were before (remembering that
the context nodes are Date elements this time rather than News
elements)?
But.... I think keeping track of context node is exactly my problem.
I thought my whole problem was sorting the results, but when I try to make
yet another group (within the group by date), I am faced with difficulties
(which I hope someone can help me with):
Taking my stylesheet below (not sorting it at the moment), I would also want
to group by P1 (the XML is at the buttom of the mail).
I thought I could do something like this:
..
<xsl:for-each select="$unique-dates">
<xsl:variable name="unique-p1s"
select=".[not(P1=preceding-sibling::News/P1)]/P1"/>
..
but I get the error:
Expected token 'eof' found '['.
.-->[<--not(P1=preceding-sibling::News/P1)]/P1
---
<xsl:variable name="unique-p1s"
select="/NewsList/List/News[not(P1=preceding-sibling::News/P1)]/P1"/>
does not give any errors, but will take _all_ P1's, not just those within a
given date (unique-dates[n], n>=1)
Can anybody can help me with how I go about things like this: what is the
context within the <xsl:for-each select="$unique-dates">, how I group within
a group (and perhaps within this, the third group..) ?
Sincerly

Part of xsl-stylesheet:
<xsl:template name="group-by-date">
<xsl:variable name="unique-dates"
select="/NewsList/List/News
[not(Date=preceding-sibling::News/Date)]/Date"/>
<xsl:for-each select="$unique-dates">
Date is: <xsl:value-of select="."/><br/>
<xsl:for-each select="/NewsList/List/News[Date=current()]">
<H1><xsl:value-of select="P1"/></H1>
into another template -->
</xsl:for-each>
</xsl:for-each>
</xsl:template>
XML input:
