I'm just having a few problems some distinct results from my query.

I have an xml document that looks something like this -

<doc>
<a>
<row>
<aa>A1</aa>
<aaa>A2</aaa>
</row>
</a>
<b>
<row>
<aa>A1</aa>
<aa>A2</aa>
<cc>C2</cc>
<cc>C1</cc>
<dd>D1</dd>
</row>
</b>
<c>
<row>
<cc>C1</cc>
</row>
</c>
<d>
<row>
<dd>D1</dd>
<ddd>D2</ddd>
<dddd>D3</dddd>
<ddddd>D4</ddddd>
<aa>A1</aa>
<aa>A2</aa>
</row>
</d>
</doc>

And my query looks something like this -

<result>
{
for
$doc in doc("doc.xml")/doc,
$a in $doc/a/row,
$b in $doc/b/row,
$c in $doc/c/row,
$d in $doc/d/row
where
$d/aa/text() = $a/aa/text() and
$d/dd/text() = $b/dd/text() and
$b/cc/text() = $c/cc/text()
return
<e>
{$d/dd}
{$d/ddd}
{$d/dddd}
{$d/ddddd}
{$a/aaa}
</e>

}
</result>

But I do, of course, get multiple results. What I can't work out is how to filter out distinct results, after all the 'joins' have been done in the where section. Can anyone help me out?

Hi Bilbo (where is Frodo??)
you will have to use distinct-values, like in this thread http://www.stylusstudio.com/SSDN/default.asp?action=9&read=6382&fid=57

Hope this helps,
Alberto
