RE: [xsl] Getting specific elements from a list

[JBryant@xxxxxxxxx]

I think Dimitre's solution is the better choice, as it avoids the overhead 
of a variable and the extra processing of the // operator. So if you ever 
want to optimize, look at Dimitre's suggestions again.

Still, I'm glad we could help you make something that works.

Thanks to all ...

I ended up using Jay Bryant's Solution, I could not get Dimitres'
solution to work, 
Kept getting blanks, although I now understand what was going on and it
looks like his solution should also work.

I just had to change Jay's solution from 

>   <xsl:variable name="EVDs" select="//EnumValueDescription"/>

To 

<xsl:variable name="EVDs" select=".//EnumValueDescription"/>

Thanks to All !
