How to verify data inside <![CDATA[ ... ]]>

Hello all!
My question is how can I verify block of data inside ... section by means of XpathMatch or Contains or any other assertion.

For example if I have SOAP response which contains:


   
      <?xml version="1.0" encoding="UTF-8"?><br />...<br />&nbsp; &nbsp; &nbsp; &nbsp; <dbExtentions><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <propertyTable><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <property><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <propertyName>ExternalTradeId</propertyName><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <propertyValue>TLT008901</propertyValue><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </property><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </propertyTable><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <trader><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <partyId>BAN_EMCRD</partyId><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <userId>SURAGO</userId><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <userName>GOP</userName><br />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </trader><br />...<br />...<br />&nbsp; &nbsp; &nbsp; &nbsp; </dbExtentions><br />&nbsp; &nbsp; </body><br /></TPML>
   


I am able to verify a single tag value by simple RegExp:
(?s).*body.*dbExtentions.*propertyTable.*property.*ExternalTradeId.*TLT008901.*

But what should be done if I need to verify the whole 
sections.

Many thx in advance!
