note that BillToParty is in a namespace
oa:BillToParty
somewhere (not in your example) in the XML there is a xmlns:oa="..."
note that this is not simply BillToParty, but BillToParty in thsi specific namespace
you have to reflect that in the XPath addressing
using oa:BillToParty instead of BillToParty in your path will work,
on the condition that you could bind "oa:" as a prefix to that namespace, as in the original document
 In XSLT that is simply adding the namespace binding to the stylesheet element.

In most dom like programming, you would need a namespacemanager.
How do you execute the XPath?

 

by: GertonePosted on 2009-10-29 at 12:49:56ID: 25697531

This would work as well, but is slower
body/child::*[1]/child::*[1]/DataArea/child::*[2]/Header/Parties/*[local-name() = 'BillToParty']/PartyId/Id/child::*[1]

local-name() tests for the namespace independent name of the element

 

by: vvsrk76Posted on 2009-10-29 at 12:58:53ID: 25697621

Thanks for reply.
I am using IBM WID.In xml we have namespace declartion.

 <aaia:AddRequestForQuote environment="Test" lang="en" revision="1.2.1"
xmlns:oa="http://www.openapplications.org/oagis"
xmlns:aaia="http://www.aftermarket.org/oagis">
I used below xpath expression, stiill itis not working
body/child::*[1]/child::*[1]/DataArea/child::*[2]/Header/Parties/oa:BillToParty/PartyId/Id

 

by: GertonePosted on 2009-10-29 at 13:00:59ID: 25697645

as I said, it will work UNDER THE CONDITION that you have a binding for your XPath,
usually a namespace manager, I don't know IBM WID, but will check it out
How do you launch the XPath?

 

by: vvsrk76Posted on 2009-10-29 at 13:04:02ID: 25697677

Thank you.
I am tesing this one

body/child::*[1]/child::*[1]/DataArea/child::*[2]/Header/Parties/*[local-name() = 'BillToParty']/PartyId/Id/child::*[1]

 

by: vvsrk76Posted on 2009-10-29 at 13:09:28ID: 25697729

Sorry,the above expression also is not working.

 

by: GertonePosted on 2009-10-29 at 13:15:16ID: 25697785

well I based tha XPath on your claim in your original question that this one is working
/body/child::*[1]/child::*[1]/DataArea/child::*[2]/Header/Parties/child::*[1]/PartyId/Id/child::*[1]
Now, when I look back at your XML, I think that claim is false.
This XPath can't possibly work
If you want to translate that into an XPath using local-name(), this is what you would get
/body/child::*[1]/child::*[1]/*[local-name() = 'DataArea']/child::*[2]/*[local-name() = 'Header']/*[local-name() = 'Parties']/*[local-name() = 'BillToParty']/*[local-name() = 'PartyId']/*[local-name() = 'Id']/child::*[1]

 

by: GertonePosted on 2009-10-29 at 13:16:02ID: 25697794

but please, give me the detail on how you execute the XPath, so I can help you making a more robust XPath, using a namespace managere, or a namespace binding of some kind

 

by: vvsrk76Posted on 2009-10-29 at 13:25:14ID: 25697875

We are using ESB product,.
In the IBM Websphere Integration Developer , we have primitives(built ins)  like "Message Filter"  in the mediation. In the properties directly we can use the xpath expression.

This XPath will work,
/*[local-name() = 'AddRequestForQuote']/*[local-name() = 'DataArea']/*[local-name() = 'RequestForQuote']/*[local-name() = 'Header']/*[local-name() = 'Parties']/*[local-name() = 'BillToParty']/*[local-name() = 'PartyId']/*[local-name() = 'Id']/text()
I have tested that with your full XML

I am looking into the WID thing you describe... a bit of code would help though,
I assume you put the XPath in a java call?

 

by: vvsrk76Posted on 2009-10-29 at 14:05:51ID: 25698263

In coming req may 'purcahse orders' type or 'shipment 'type or 'quote'.
We need to use common filter.
