WSO2 xml property xpath to child element

I have following code:

<property name="resultOM" scope="default" type="OM">
    <test><test1>testing111</test1></test>
</property>

<log level="full">
    <property name="ROOT" expression="$ctx:resultOM" />
    <property name="resultOM.test" expression="$ctx:resultOM//test1" />
</log>

Then I would expect to see in logs values ROOT = testing111 resultOM.test = testing111

and although ROOT value is fine, the value of resultOM.test is empty. What should be the correct xpath to retrieve the child value? Version of used WSO2ESB is 4.5.1.

A default namespace (http://ws.apache.org/ns/synapse) is defined when you create an OM type property. So you need to perform xpath expressions with namespaces. Try this;

<log level="full">
   <property name="ROOT" expression="$ctx:resultOM"/>
   <property name="resultOM.test" xmlns:ns="http://ws.apache.org/ns/synapse" expression="$ctx:resultOM//ns:test1"/>
</log>
