Re: [xsl] document() merge DISTINCT

["Alex Schuetz" <asc@xxxxxx>]

Hallo Chris,

it does not work for me as expected..

I guess, I do not understand the meaning on current() in this context:

To make it simpler for me, say I have more then two  files I want to merge
as:

sample.xml:
<p>
<person name="name2" id="2"/>
<person name="name3" id="8"/>
<person name="name4" id="32"/>
</p>

In each file all /person/@id are unique, but different files might contain
the same @id .
Now I want to produce a list of all <person> so that /person/@id is unique.

As you suggested, I tried:

<xsl:template match="person">
 <xsl:copy>
 <xsl:copy-of
 select="document($file)/p/person[not(@id = current()/p/person/@id]"/>
  </xsl:copy>
 </xsl:template>

It looks to me, that [not(@id = current()/p/person/@id] is always true and I
get a list with non unique <person>.

-Alex
