Subject: [xsl] xslt 1.0 vs xslt 2.0 problem

Dear Gents:
 
I have looked everywhere for the solution to this problem and 
never seem to get what to the root of the issue. Here is the 
problem in a nutshell:
 
I have XML of this structure:
 
<resp>
 <A>
  <B a="foo bar bar"></B>
  <B a="bar bar foo"></B>
  <B a="boo far far"></B>
 </A>
 <A>
  <B a="far boo"></B>
  <B a="foo bar foo"></B>
  <B a="bar foo bar"></B>
 </A>
</resp>
 
Using XSLT 1.0 (which I must, since I am constrained to use 
ASP.NET 2.0) I need to query the XML above to find all <A> if 
any of its children <B> fulfill a certain requirement.
 
//A[ contains(B/@a, "foo") ]

What I am seeing is that this XSL only checks the FIRST child 
node's (B) attribute instead of checking all of them. In 
other words, I only get this:
<resp>
 <A>
  <B a="foo bar bar"></B>
 </A>
</resp>
...instead of what I need, namely this:
<resp>
 <A>
  <B a="foo bar bar"></B>
  <B a="bar bar foo"></B>
 </A>
 <A>
  <B a="foo bar foo"></B>
  <B a="bar foo bar"></B>
 </A>
</resp>

An attempt to alleviate this problem by amalgamating all the 
<B> together using string-join, i.e.

//A[ contains( string-join(B/@a), "foo") ]

error-out because string-join is XSLT 2.0

So...what is the correct way to query through all child nodes 
using xslt 1.0?

Thanks Guys!

Sincerely,
