To test libxml2-python you need some data and some python. The script previously given actually used expat, not libxml2, and has been transferred to a new Wiki page for testing expat. This script uses libxml2.

Save the follow python as testxml.py

import libxml2

def getStatus(case):
    prop = case.properties
    props={}
    props['name']=""
    props['classname']=""
    props['status']=""
    while prop:
        props[prop.name]=prop.content
        prop=prop.next
    if props['name'] == 'VHDL_BUILD_Passthrough' and props['classname'] == 'TestOne':
        return props['status']
    return None

x = libxml2.parseFile("testdata.xml")
allcases=[c for c in x.children if c.name == 'testcase']
cases = [c for c in allcases if getStatus(c) != None]
print(getStatus(cases[0]))

Save the following xml data as testdata.xml

<?xml version="1.0" encoding="UTF-8"?>
<testsuites tests="10" failures="0" disabled="0" errors="0" time="0.001" name="AllTests">
  <testsuite name="TestOne" tests="5" failures="0" disabled="0" errors="0" time="0.001">
    <testcase name="DefaultConstructor" status="run" time="0" classname="TestOne" />
    <testcase name="DefaultDestructor" status="run" time="0" classname="TestOne" />
    <testcase name="VHDL_EMIT_Passthrough" status="run" time="0" classname="TestOne" />
    <testcase name="VHDL_BUILD_Passthrough" status="Tested OK" time="0" classname="TestOne" />
    <testcase name="VHDL_SIMULATE_Passthrough" status="run" time="0.001" classname="TestOne" />
</testsuite>
</testsuites>

Usage & expected output..

Chromium-browser uses libxml2 and running under strace will show it is loading it. Viewing some xml files you can find online should be enough to show it is working.

$ strace -o strace.out chromium-browser
$ grep xml strace.out
