For the STP XEF editor I refactored the code (that was using Jaxen through JDom) to use the Dom-based JAXP XPath API's javax.xml.xpath.XPath/javax.xml.xpath.XPathFactory. These API's are part of the JRE so they don't introduce any additional dependencies.
For more details see the getXMLSnippet()/putXMLSnippet() methods in http://dev.eclipse.org/svnroot/stp/trunk/org.eclipse.stp.policy/org.eclipse.stp.xef/src/org/eclipse/stp/xef/XMLUtil.java
Cheers,
