wso2 response property to filter mediator

I'm trying to use the Filter mediator for my response to check whether the response is a collection.

So what I did here is to check whether the element id in belongs_to_collection is a numeric

<property expression="/soapenv:Envelope/soapenv:Body/root:movie/belongs_to_collection/id" name="collection" scope="default" type="STRING"/>
<filter description="" regex="[0-9]+" source="get-property('collection')">...</filter>

Here's my full api config http://pastebin.com/QA3GCd1W

and here's the response to be filter http://pastebin.com/0dxweJu3

If you don't want to deal with namespaces, you can use local-name() like this.

<property name="collection" 
expression="//*[local-name()='belongs_to_collection']/*[local-name()='id']/text()" 
scope="default" 
type="STRING"/>

If you use namespace prefixes in your expression you need to define those namespaces. For example:

    <property expression="/root:movie/belongs_to_collection/id" 
name="collection" scope="default" type="STRING" xmlns:root="www.wso2esb.com"/>

The response I see when using your API however is 

<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Body>
        <jsonObject>
            <belongs_to_collection>
                <id>8650</id>
...

Your root element is the soapenv:Envelope tag, so you don't have to put that in your expression anymore. The / at the beginning refers to the root element. Anything after that refers to elements inside your root element.

So the expression should be as follows:

<property xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
name="collection" expression="/soapenv:Body/jsonObject/belongs_to_collection/id" 
scope="default" type="STRING"/>
