Hi Sohani,
May be your expression syntax is incorrect. Is it works when it change like
expression="fn:string-join(('name','age'), '-').I'm referring to [1].[1]-http://www.xqueryfunctions.com/xq/fn_string-join.html THanks, Harsha On Tue, Jun 3, 2014 at 1:36 PM, Sohani Weerasinghe <[email protected]> wrote: > Hi All, > > I am using an XPATH expression as follows, > > <sequence xmlns="http://ws.apache.org/ns/synapse"; name="sequence1"> > <log level="custom"> > <property xmlns:ns="http://org.apache.synapse/xsd"; > xmlns:fn="http://www.w3.org/2005/xpath-functions"; name="insq" > expression="fn:string-join('name','age', '-')"/> > </log> > <drop/> > </sequence> > > When I invoke the proxy I am getting an error as follows > > SynapseXPath Evaluation of the XPath expression fn:string-join('name','age', > '-') resulted in an error > > org.jaxen.UnresolvableException: No Such Function > {http://www.w3.org/2005/xpath-functions}:string-join > > at > org.jaxen.SimpleFunctionContext.getFunction(SimpleFunctionContext.java:127) > > at > org.apache.synapse.util.xpath.SynapseXPathFunctionContext.getFunction(SynapseXPathFunctionContext.java:93) > > at org.jaxen.ContextSupport.getFunction(ContextSupport.java:242) > > at org.jaxen.Context.getFunction(Context.java:216) > > at > org.jaxen.expr.DefaultFunctionCallExpr.evaluate(DefaultFunctionCallExpr.java:172) > > at org.jaxen.expr.DefaultXPathExpr.asList(DefaultXPathExpr.java:102) > > at org.jaxen.BaseXPath.selectNodesForContext(BaseXPath.java:674) > > at org.jaxen.BaseXPath.selectNodes(BaseXPath.java:213) > > at org.jaxen.BaseXPath.evaluate(BaseXPath.java:172) > > at > org.apache.synapse.util.xpath.SynapseXPath.stringValueOf(SynapseXPath.java:297) > > at > org.apache.synapse.mediators.MediatorProperty.getEvaluatedExpression(MediatorProperty.java:138) > > at > org.apache.synapse.mediators.builtin.LogMediator.setCustomProperties(LogMediator.java:192) > > at > org.apache.synapse.mediators.builtin.LogMediator.getCustomLogMessage(LogMediator.java:131) > > at > org.apache.synapse.mediators.builtin.LogMediator.getLogMessage(LogMediator.java:117) > > at > org.apache.synapse.mediators.builtin.LogMediator.mediate(LogMediator.java:91) > > at > org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:77) > > at > org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:47) > > at > org.apache.synapse.mediators.base.SequenceMediator.mediate(SequenceMediator.java:131) > > at > org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:77) > > at > org.apache.synapse.mediators.AbstractListMediator.mediate(AbstractListMediator.java:47) > > at > org.apache.synapse.mediators.base.SequenceMediator.mediate(SequenceMediator.java:131) > > at > org.apache.synapse.core.axis2.ProxyServiceMessageReceiver.receive(ProxyServiceMessageReceiver.java:166) > > at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:180) > > at > org.apache.synapse.transport.passthru.ServerWorker.processEntityEnclosingRequest(ServerWorker.java:411) > > at > org.apache.synapse.transport.passthru.ServerWorker.run(ServerWorker.java:183) > > at > org.apache.axis2.transport.base.threads.NativeWorkerPool$1.run(NativeWorkerPool.java:172) > > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) > > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) > > at java.lang.Thread.run(Thread.java:722) > > > According to [1] it states the string-join function should be as follows, > > fn:string-join(('name','age'), '-') - with two brackets but when I try to do > so, ESB doesn't support this. > > [1] > http://www.w3.org/TR/2014/REC-xpath-functions-30-20140408/#func-string-join > > Can someone please state the correct way of writing the XPATH expression ? > > Thanks, > Sohani > > Sohani Weerasinghe > Software Engineer > WSO2, Inc: http://wso2.com > > Mobile : +94 716439774 > Blog :http://christinetechtips.blogspot.com/ > Twitter : https://twitter.com/sohanichristine > > _______________________________________________ > Dev mailing list > [email protected] > http://wso2.org/cgi-bin/mailman/listinfo/dev > > -- Harsha Kumara Software Engineer, WSO2 Inc.
