[cji_work]

Hi all,
I have such an xml file,
"
<p class="group changelink">
<label for="paymentmethod">Payment Method:</label>
<span class="field">Credit/Debit Card : MasterCard XXXX-XXXX-XXXX-0537<span class="fundamount">$1.00 USD</span></span>
</p>
"
How can I extract the value of
"
Credit/Debit Card : MasterCard XXXX-XXXX-XXXX-0537
"
in XPATH.


Thanks a lot
