Question

I’m struggling with the BizTalk xpath functionality


– the message I’m getting has a blank default namespace


– in C# I’d add a NameSpaceManager

– but I can’t see how I can do this in a BizTalk Expression ?

All I’m failing to do is get the values of the HasErrors and NumberOfErrors

<?xml version="1.0" encoding="utf-8"?>
<ImportIndexDocumentResponse   
      xmlns:xsd="http://www.w3.org/2001/XMLSchema"        
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns="http://www.aniteps.com/xml/schemas/awm/images4">
  <HasErrors>false</HasErrors>
  <NumberOfErrors xsi:type="xsd:int">0</NumberOfErrors>
  <ErrorDescription xsi:type="xsd:string">No exception ocurred.</ErrorDescription>
  ...

Answer 1

The answer using local-name() is wrong as it allows unwanted elements to be selected, such as:

• OhMy:HasErrors
• Different:HasErrors
• UnWanted:HasErrors

Here is one correct solution:

In case it is not possible to bind a prefix to the default namespace “http://www.aniteps.com/xml/schemas/awm/images4“, one can use the standard XPath function namespace-uri() to specify that the element must reside in a given namespace.

Thereforere, one example of XPath expressions that select the wanted two kind of nodes is:

/*/*[namespace-uri() = 'http://www.aniteps.com/xml/schemas/awm/images4'
   and
     name() = 'HasErrors'
    ]

and the expression:

/*/*[namespace-uri() = 'http://www.aniteps.com/xml/schemas/awm/images4'
   and
     name() = 'NumberOfErrors'
    ]
