Hi all,
can you please tell me if it's possible to group by 2 elements?
A simplified example:
<page>
<ROWSET>
<ROW>
<country>Canada</country>
<language>french</language>
</ROW>
<ROW>
<country>Canada</country>
<language>english</language>
</ROW>
<ROW>
<country>Switzerland</country>
<language>german</language>
</ROW>
<ROW>
<country>Switzerland</country>
<language>french</language>
</ROW>
</ROWSET>
</page>
When I try something like
<xsl:for-each select="ROW[country=$country]
[not(language=preceding-sibling::ROW/language)]/language">
the result is english, french and german when specifying Switzerland
as country.
And when I try
<xsl:for-each select="ROW
[not(../ROW[country=$country]/language=preceding-sibling::ROW[country=$country]/language)]/language">
the result is german.
My favourite result were german and french when specifying Switzerland.
Should I do a reorder first?
Something like
<country>
<language>...</language>
</country>
Or is there a solution so that reordering is not necessary?
Thank you very much,
Günter
