PyXML minidom parsing problems
Problēma ir sekojoša. Ir XML fails:

<?xml version="1.0" encoding="UTF-8"?>

            </trans-unit>
            <trans-unit resname="IDS_4" id="004">
                <source>

                </target>
            </trans-unit>
        </body>
    </file>
</xliff>

Ir Python skripts, ar kura palīdzību katras <target>...</target> virknes beigās pievienot newline, goes like this:

#!/usr/bin/env python

import sys
import getopt
from xml.dom import minidom

def usage():
    print >> sys.stderr, 'Usage: parse.py --file file_name'
   
def ferror():
    print >> sys.stderr, 'Cannot open file'
    sys.exit(2)

def main(argv):
    if len(argv) != 1:
        usage()
        sys.exit(2)
   
    try:
        opts, args = getopt.getopt(argv, "hf:", ["help", "file="])
    except getopt.GetoptError, err:
        print str(err)
        usage()
        sys.exit(2)
      
    for opt, arg in opts:
        if opt in ("-h", "--help"):
            usage()
            sys.exit()
        elif opt in ("-f", "--file"):
            fileName = arg
        else:
            assert False, "unhandled option"
   
    try:
        dom = minidom.parse(fileName)
        file = open(fileName, 'w')
    except:
        ferror()

    rc = ''

    for node in dom.getElementsByTagName('target'):
        if node.firstChild.nodeType == minidom.Node.TEXT_NODE:
            rc = node.firstChild.data + '\n'
            node.firstChild.data = rc
         
    file.write(dom.toxml('utf-8'))
    file.close()

if __name__ == "__main__":
    main(sys.argv[1:])

Problēma sastāv no apstākļa, ka tāda vai citāda iemesla dēļ XML parseris apstājas pie <ph>...</ph> taga un ievieto newline tur, ignorējot atlikušo virknes daļu.
