select unique name

Hi All,

I'm new to xsl and xpath. I have a pmd xml report (xml
below). What I would like to do is to display all test
names, like:

\test00
\test10
\test20


I manage to get a name of single test: 
<xsl:variable name="name"
select="substring-before(substring-after(@name,'build'),'src')"/>
   

and I know how to display all 5 @names, but I don't
know how to select unique names.  

\test00
\test00
\test10
\test10
\test20

</file>
</pmd>


Can any body tell me how to solve it?
