indika priyantha kumara commented on SYNAPSE-503: ------------------------------------------------- I have tried the following <property name="body" expression="$body/child::*[position()=1]" /> <xquery key="response.xq" trace="enable"> <variable name="payload" type="ELEMENT"/> <variable name="request" expression="synapse:get-property('body')" type="ELEMENT"/> </xquery> and for XLST mediator too , I have tried . It is now working. Take svn up Thanks Indika > get-property function is not recognized in xquery variable expression > attribute > ------------------------------------------------------------------------------- > > Key: SYNAPSE-503 > URL: https://issues.apache.org/jira/browse/SYNAPSE-503 > Project: Synapse > Issue Type: Bug > Components: Extension Mediators > Affects Versions: 1.3 > Reporter: Michal Stochmialek > Assignee: indika priyantha kumara > Fix For: 1.3 > > > I'm transforming response of the remote service in outSequence of a proxy. > I'm using xquery mediator.
