You need to fully specify the xpath, including namespaces.
The easiest way to do this is open the schema, select the node and copy the [b:c9a7ccebf4]Instance XPath[/b:c9a7ccebf4] property.It should look something like this:
/*[local-name()=’ContraxMSgs’ and namespace-uri()=’http://MyCompany.MyApp.Messaging.BizTalk’%5D/*%5Blocalname=’ContraxMSg’ and namespace-uri()=’http://MyCompany.MyApp.Messaging.BizTalk’%5D/*%5Blocalname=’MESSAGEID’ and namespace-uri()=’http://MyCompany.MyApp.Messaging.BizTalk’%5D -
Which xpath string produced this error.
[code:1:465b2e19ff]//ContraxMSgs/ContraxMSg/MESSAGEID[/code:1:465b2e19ff]
Or
[code:1:465b2e19ff]/*[local-name()=’ContraxMSgs’ and namespace-uri()=’http://MyCompany.MyApp.Messaging.BizTalk’]/*[localname=’ContraxMSg’ and namespace-uri()=’http://MyCompany.MyApp.Messaging.BizTalk’]/*[localname=’MESSAGEID’ and namespace-uri()=’http://MyCompany.MyApp.Messaging.BizTalk’][/code:1:465b2e19ff]Do both xpath strings return the same error?

Can you email me the schema for this message.
Can you also save the message that errors and send that as well-
I have a message that looks like this:
[code:1:b33f97af56]
<ContraxMSgs xmlns=\"http://MyCompany.MyApp.Messaging.BizTalk\">
<ContraxMSg>
<MESSAGEID>177629</MESSAGEID>
<MESSAGE_TYPE_ID>9</MESSAGE_TYPE_ID>
<CONTRAX_COMPANY_PARTYID>8147</CONTRAX_COMPANY_PARTYID>
<SUBJECT>invoice ready.</SUBJECT>
<TYPE>Invoice Ready</TYPE>
<PRIORITY>HIGH</PRIORITY>
<TEXT>Blah Blah. Thank you.</TEXT>
<EXPIRY_DATE>2004-06-10T00:00:00.0000000-04:00</EXPIRY_DATE>
</ContraxMSg>
</ContraxMSgs>
[/code:1:b33f97af56]
I’m trying to use an expression shape to get the number of records (even though it is one record everytime) and MessageID. I’m using this xpath:
[code:1:b33f97af56]
varTotal = System.Convert.ToInt32(xpath(msgIn, \"count(//ContraxMSg)\"));
sTemp = xpath(msgIn,\"//ContraxMSgs/ContraxMSg/MESSAGEID\");
sResult = \"OrcMessaging -> The total number of Messages are \" + System.Convert.ToString(varTotal) + \" MessageID: \" + sTemp;System.Diagnostics.Debug.WriteLine(sResult);
[/code:1:b33f97af56]
The result though is 0 messages and blank message id. However when I use xmlspy I’m returning 1 message with the correct Message ID so I’m thinking it is the correct xpath.How come I’m not getting the right results? Anyone see something that I’ve missed.
Thanks, Bill N

Thanks Greg for the reply.
Again, in XMLSpy the xpath works correctly. However I’m getting this application error in the event viewer:

A little deeper into HAT, I get:

System.InvalidOperationException
[/code:1:de243100e0]I don’t know if any of this helps. Any ideas what could cause the xpath to error?
Thanks, Bill N

This code returns null:
[code:1:3089b7d000]//ContraxMSgs/ContraxMSg/MESSAGEID[/code:1:3089b7d000]
This code returns the exception:
[code:1:3089b7d000]
/*[local-name()=’ContraxMSgs’ and namespace-uri()=’http://MyCompany.MyApp.Messaging.BizTalk’]/*[localname=’ContraxMSg’ and namespace-uri()=’http://MyCompany.MyApp.Messaging.BizTalk’]/*[localname=’MESSAGEID’ and namespace-uri()=’http://MyCompany.MyApp.Messaging.BizTalk’]
[/code:1:3089b7d000]
I thought maybe I’m making some mistake with what I think the schema and/or xml message should look like but in my orchestration I have a receive shape with the correct message and then I have a send shape that just sends the message out to some folder as an xml file.Hope this helps (especially as I’m getting desperate)
