If it's about pure XML parsing and tweaking the information and building the model is not required, XmlBeam [0] is a lightweight alternative to map the entire file to a Java object. We use that in the Spring Data release automation. Declare an interface containing accessors backed by XPath expressions, use the API to create instances and read and write data from and to the XML file.
Here [1] is the interface we use to access the parts of the POM relevant to our use case.
