I'm writing a Burp extension and need to parse some XML. Using xml.etree.ElementTree, I'm running into this issue. Essentially:
SAX for some reason explicitly uses thread's contextClassLoader or system classloader instead of the parent classloader.
Which results in:
org.xml.sax.SAXException: SAX2 driver class org.apache.xerces.parsers.SAXParser not found
java.lang.ClassNotFoundException: org.apache.xerces.parsers.SAXParser
None of the suggestions have worked for me, and I'm not sure how to resolve this. Since Burp uses a jython stand alone file, is there a way to manually inject the missing class file into the standalone .jar? Every way I've tried results in Burp not being able to load the python environment.
How can I parse XML within a Burp extension?
