If you can't or don't want to move to an XSLT 2.0 processor the only 
option in XSLT 1 I see is matching only on
  <xsl:template match="wix:Component[wix:File]">
    <xsl:if test="wix:File[substring(@Source, string-length($var) - 1) 
= $var2">...</xsl:if>
  </xsl:template>
Depending on other templates you have or need instead of the xsl:if you 
might want to use an xsl:choose/xsl:when to deal with various conditions.
