Hi,

I have a question about XPath query in WSBPEL. Its Xpath query is not the same as a normal Xpath.

Let's take an example from WSBPEL 2.0 specification, a BPEL query:

<from>$Results/e:AuctionResult[2]/@AuctionID</from>

but a normal XPath1.0 should perform something like:

e:complexType[@name='AuctionResults']/e:sequence/e:element[name='AuctionResult']... --> BPEL query cares only about the ELEMENT NAME and ATT name.

The question is how can I take the BPEL query "/e:AuctionResult[2]/@AuctionID" as an input and perfrom a right Xpath query in WSDL? Because when BPEL query uses some additional XPath functions library, the problems are complex to translate to the right XPath query as above.

Hope someone would help

I'm really appreciate. Thank you very much
