Hi, Mike,
That's a question to which you can find an answer in Dave Pawson's FAQ at
http://www.dpawson.co.uk/xsl/sect2/N2696.html
In your case, something like the following will do the trick:
<xsl:template match="page[not(@tab=following::page/@tab)]">
<!-- Process the page nodes with unique values for the tab attribute
here -->
</xsl:template>
You can do the same trick in the select attributes of apply-templates or
for-each instructions, too, depending on exactly what you need to do.

Subject: [xsl] Exclude by Sibling Condition
Considering the following XML fragment:
<page name="p0" tab="products"/>
<page name="p1" tab="products"/>
<page name="p2" tab="products"/>
<page name="d" tab="downloads"/>
<page name="s" tab="support"/>
How can I select a subset that excludes elements with a tab attribute
value matching that of a previous sibling?
Meaning I want a list with no redundant @tab values like:
<page name="p0" tab="products"/>
<page name="d" tab="downloads"/>
<page name="s" tab="support"/>
Thanks,
Mike
