WSO2 using xpath to get element inside a xml-content property

Question

I have got an local entry in wso2 esb which contains an xml structure. I succeed in loading it into a property, but fail to perform xpath sentences over it for looking for a node value.

How could I do this?

Answer 1

The elements in a XML file(this can be in a local entry , registry or even as a property) can be accessed using property mediator function. Following sample configuration shows how to get the value of the node 'b' in test.xml file in the local config repository.

ie:- test.xml --> <a>Helloo<b>World</b></a>

<property name="test" expression="get-property('registry','conf:/test.xml')" scope="default" type="OM"/>
<log level="custom">
      <property name="test.b" expression="$ctx:test//b"/>
</log>
