[xsl] Creating intermediate XML fragment

["alexandre bord" <alexandre.bord@xxxxxxxxxx>]

Hello !
Suppose my (piece of) xml looks like this :
<foobar name="fff" />
<foobar name="dddd" />
<bar name1="dddd" name2="xxx"/>
<bar name1="xxx" name2="yyy"
<foo name="yyy" />
<foo name="zzz" />

I'd like to output :
fff
dddd (once)
xxx (once)
(not 'yyy' nor 'zzz')
And i suppposed i could create an intermediate xml fragment and work on 
it to write names once ?

Thanx for your help
Alex
