Ah sorry, I missed that subtlety. So the first sort key is @active,
descending, and the second is (active = published), false<true:
<xsl:sort select="number(@active = @published)" data-type="number"/>
(or in XSLT 2.0 you can sort booleans directly, with false<true, giving
<xsl:sort select="@active eq @published" />
Alternatively, you can probably do it with a single sort key:
<xsl:for-each select="project">
<xsl:sort select="substring('dcab', 2*(_at_)active + @published + 1, 1)"/>
But I haven't tested it and it's a bit obscure for practical use.

Subject: Re: [xsl] Sorting on two booleans
That gives me
active, not published
active, published
not active, not published
not active, published
But I need the last two reversed.
not active, published
not active, not published
Thanks

I've got a document that looks like this:
<projects>
<project active="1" published="1">stuff</project>
<project active="1" published="0">stuff</project>
<project active="0" published="1">stuff</project>
<project active="0" published="0">stuff</project> </projects
And I need to be able to sort them (on the fly - it's part of a
sortable table in html) in this order and the reverse:
active, not published
active, published
not active, published
not active, not published.
So your major sort key is @active (true<false) and your
minor sort key
is @published (false<true).
That's
<xsl:for-each select...>
<xsl:sort select="@active" data-type="number" order="descending"/>
<xsl:sort select="@published" data-type="published"
order="ascending"/>
For the reverse order, flip all the order="" attributes.

I've tried all kinds of ways to sort them to get this to happen
including brute force:
<xsl:for-each select="project">
<xsl:sort select="@active=1 and
@published=0"
order="ascending"
data-type="number"/>
<xsl:sort select="@active=1 and
@published=1"
order="ascending"
data-type="number"/>
<xsl:sort select="@active=0 and
@published=1"
order="ascending"
data-type="number"/>
<xsl:sort select="@active=0 and
@published=0"
order="ascending"
data-type="number"/>
<xsl:copy-of select="."/>
</xsl:for-each>
Nothing works. It always comes out with at least one in the wrong
spot.
Could someone point me in the right direction? Help me understand
what I'm missing about how sort works?
Thanks much in advance
