Class XQueryMediator

java.lang.Object

org.apache.synapse.mediators.AbstractMediator

org.apache.synapse.mediators.xquery.XQueryMediator

All Implemented Interfaces:

org.apache.synapse.aspects.AspectConfigurable, org.apache.synapse.Mediator, org.apache.synapse.SynapseArtifact

public class XQueryMediator
extends org.apache.synapse.mediators.AbstractMediator

The XQueryMediator provides the means to extract and manipulate data from XML documents using XQuery . It is possible to query against the current SOAP Message or external XML. To query against the current SOAP Message ,it is need to define custom variable with any name and type as element,document,document_element By providing a expression ,It is possible to select a custom node for querying.The all the variable that have defined in the mediator will be available during the query process .Basic variable can use bind basic type. currently only support * string,int,byte,short,double,long,float and boolean * types. Custom Variable can use to bind XML documents ,SOAP payload and any basic type which create through the XPath expression .
