[xsl] Testing if multiple nodes contain values

[Jonathan Kart <jkart@xxxxxxxxxxxx>]

Hi all,

I'm sure i should be spending more time on this myself, but i'm in a 
bit of a time crunch and i can't seem to find what i'm looking for.

I'm trying to test to see if multiple nodes contain a value.
xml is like:

<publication_1>a publication</publication_1>
<publication_2>a publication</publication_2>
.
.
.
<publication_n>a publication</publication_n>

i want to do, in pseudocode
<xsl:if test="any node which starts with publication_ has a value">
	do something
</xsl:if>

is it possible to concatenate string values of a nodeset together? (in 
xsl 1.0)
something like:
<xsl:test select="concat(*[starts-with(name(),'publication_')]) !='' ">


again, this may be simple.  sorry.  I wish i had more time to research 
it on my own.

Thanks for any help,
jonathan
