For FUSE related questions you should use the FUSE forums; these forums are for the Apache distros... http://open.iona.com/forums/index.jspa When routing XML messages using Camel http://activemq.apache.org/camel/ you can use various expression languages like XPath or XQuery to do routing but its easy to add your own expression mechanism (you can use any Java code to evaluate an expression); when using XPath by default we use JAXP under the covers to evaluate XPath expressions. If you use Artix Data Services for your XML payloads then it uses fast in memory objects... http://activemq.apache.org/camel/artix-data-services.html We've a pending JIRA for SXC support which might help for more high performance XML based routers using a more pull mechanism - but that only supports a subset of XPath. http://issues.apache.org/activemq/browse/CAMEL-326 > What is the performance number etc? We've no specific performance tests; it kinda depends what your XML looks like and what kinds routes you're doing. -- James ------- http://macstrac.blogspot.com/ Open Source Integration http://open.iona.com
