Python 2.6.1 : expected path separator ([)

Question

I am getting a path separator error in python 2.6.1. I have not found this issue with python 2.7.2 version, but unfortunately I need this in 2.6.1 only. Is there any another way to achieve the same? :(

my code :-

import xml.etree.ElementTree as ET #version 1.2.6
import sys   

class usersDetail(object): 

    def __init__(self, users=None):
        self.doc = ET.parse("test.xml")
        self.root = self.doc.getroot()

    def final_xml(self,username):
        r = self.root.find("user[@username='user1']") #not working in 2.6.1 :(
        self.root.remove(r)
        print r
        tree = ET.ElementTree(self.root)
        tree.write("msl.xml") 

if __name__ == '__main__':
    parser = usersDetail()
    parser.final_xml("user1") 

test.xml is :-

<?xml version="1.0"?>
<users>
<user afp="yes" cifs="yes"  username="user1" volume="vol" webdev="yes" /></user>
</users>

What this will do is it will remove the xml only if username = username. Thanks in advance for your valuable time.

You are using an XPath expression, that is not supported by the ElementTree version included in Python 2.6. You'll need to filter for the attribute manually, after a .findall():

def final_xml(self,username):
    users = self.root.findall("user")
    for user in users:
        if user.attrib.get('username') == 'user1':
            break
    else:
        raise ValueError('No such user')

    # `user` is now set to the correct element
    self.root.remove(user)
    print user
    tree = ET.ElementTree(self.root)
    tree.write("msl.xml")
