Sure. You can grab all the Payment_Pattern nodes in the document with the 
XPath "//Payment_Pattern" (short for 
"/descendant-or-self::node()/child::Payment_Pattern": aren't you glad 
there's a short version?). These can be concatenated into a single Result 
Tree Fragment using a copy-of instruction, and bound to a variable:

<xsl:variable name="PPatterns">
  <xsl:copy-of select="//Payment_Pattern"/>
</xsl:variable>

Then you can treat the variable $PPatterns like a string. So

<xsl:value-of
  select="string-length($PPatterns) - 
string-length(translate($PPatterns,'2','')"/>

will tell you how many 2s appear throughout your entire set of 
Payment_Patterns.

I hope that helps.

Cheers,
Wendell
