[ptt-users] Help with Xpath

[Norm Dressler]

My xml snippit looks like this:
        <hl7:clientIDPub>
		<hl7:value root="2.16.840.1.113883.4.52" extension=""
displayable="true"></hl7:value>
        </hl7:clientIDPub>

In the Properties Transfer, if I put //hl7:clientIDPub//hl7:value it
injects the value so I know its finding the clientIDPub.  I want it to
inject the value into extension.  How do I define the xpath for that?

Thanks for any help.
