Hi, Your xpath is not correct.. It needs to be like; <validate xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; source="/soapenv:Envelope/soapenv:Body/huisdier">

I've already done some tests with proxy services and different type of endpoint which all seem to work correctly. I would like to extend one of my proxy services with a validation mediator. But each time when I call my proxy service, I'm getting the following error message back: ValidateMediator The evaluation of the XPath expression /huisdier did not result in an OMNode : null Below the content of my proxy service: <proxy xmlns="http://ws.apache.org/ns/synapse"; name="validateXMLProxyNDV" statistics="disable" trace="enable" transports="http,https"> <target endpoint="fileshareEndpointNDV"> <inSequence> <log category="INFO" level="full" separator=","/> <validate source="/huisdier" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <on-fail> <log category="TRACE" level="simple" separator=","> <property name="Text" value="XML file is not valid"/> </log> </on-fail> <schema key="/_system/NBB/schema/huisdier.xsd"/> </validate> <log category="TRACE" level="simple" separator=","> <property name="Text" value="Message is valid"/> </log> <property action="set" name="OUT_ONLY" scope="default" type="STRING" value="true"/> </inSequence> </target> </proxy> And this is the message we are receiving: <?xml version='1.0' encoding='utf-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";><soapenv:Body> <huisdier xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:noNamespaceSchemaLocation="huisdier.xsd"> <soort>Kanarie</soort> <naam>Geeltje</naam> <geboortedatum>2000-02-15</geboortedatum> </huisdier></soapenv:Body></soapenv:Envelope> Can someone tell me what is wrong with my xpath expression ? ----------------------------------------- Visit our website! http://www.nbb.be "DISCLAIMER: The content of this e-mail message should not be construed as binding on the part of the National Bank of Belgium (NBB) unless otherwise and previously stated.
