Not able to parse string-xml through parseEscapedXml

Question

Hi all,
What I am doing is, I am getting some data through polling and populating a schema variable. Because of having extra namespace in the resultant xml, I again used processXSLT and assigned the resultant xml to a string variable (after converting it to string).
Now I want to pass this string to my web service. When I tried the
ora:parseEscapedXML(ora:getContentAsString(bpws:getVariableData('niku_xog_project_write_xml_as_string')))
It is giving the xpath error ORABPEL-09500. However when I remove the parseEscapedXML function, I am able to see the correct data on server. But it doesn't work because web-service expecting the xml instead of string.
Below is the xml in string format. I picked it from server log.

Tried this...
<copy>
<from expression="ora:parseEscapedXML(translate(bpws:getVariableData('niku_xog_project_write_xml_as_string')), '&amp;', '&amp;amp;')"/>
<to variable="Invoke_2_write_project_WriteProject_InputVariable"
part="body" query="/niku:WriteProject"/>
</copy>
still not working :(
