quick maven pom parser for group, artifact, and version

parse-pom.py

#!/usr/bin/python

from xml.etree import ElementTree as et

import sys

if __name__ == "__main__":
  ns = "http://maven.apache.org/POM/4.0.0"

  for filename in sys.argv[1:len(sys.argv)]:
    group = artifact = version = ""

    tree = et.ElementTree()
    tree.parse(filename)

    p = tree.getroot().find("{%s}parent" % ns)

    if p is not None:
      if p.find("{%s}groupId" % ns) is not None:
        group = p.find("{%s}groupId" % ns).text

      if p.find("{%s}version" % ns) is not None:
        version = p.find("{%s}version" % ns).text

    if tree.getroot().find("{%s}groupId" % ns) is not None:
      group = tree.getroot().find("{%s}groupId" % ns).text

    if tree.getroot().find("{%s}artifactId" % ns) is not None:
      artifact = tree.getroot().find("{%s}artifactId" % ns).text

    if tree.getroot().find("{%s}version" % ns) is not None:
      version = tree.getroot().find("{%s}version" % ns).text

    print "mvn:%s/%s/%s" % (group, artifact, version)

Going from the very top to the bottom you'll omit tag data if e. g. is also defined in the document root.
