XPath 2.0 is supported in WSO2 ESB from version 4.5.0 onwards. It's disabled by default, so you need to do the following to enable it.

  • Open $ESB_HOME/repository/conf/synapse.properties

  • Uncomment the following line,

    synapse.xpath.dom.failover.enabled=true

To access properties in a proxy service, you need to use the prefix syn.

ex.

<property expression="syn:get-property('myProperty')" name="getMyProperty" scope="default" type="STRING"/>

As far as I can tell from the JavaDocs, the synapse XPath implementation is built on Jaxen, which is XPath version 1.0 only. Therefore none of those functions will be supported, you only have the very limited function library of XPath 1.0 plus the synapse-specific get-property extension.
