To rephrase what you want a bit, you want to match/select all the <elemB>
nodes which contain an <elemC> which itself contains the searchstring, and
output the first <elemC> of that element. Try:

<xsl:param name="string" select="'foo'"/>

<xsl:for-each select="elemA/elemB[contains(elemC,$string)]">
  <xsl:value-of select="elemC[1]"/>
</xsl:for-each>

Or similar.

Cheers,

Stuart
