Question

I am kinda new to Python. I am working on a project that parses an XML in Python and my Python code to do so is :

from xml.dom import minidom
from copy import copy

class Xmlparse:


    def __init__(self, xmlfile):
        self = minidom.parse(xmlfile)

    def findadress(self):
        itemlist =self.getElementsByTagName('addresses')
        return itemlist[0].attributes['firstname'].value


if __name__ == '__main__':
    with open("sample.xml") as f:

        parse = Xmlparse(f)
        print parse.findadress()

But when I run this code I get an output error:

AttributeError: Xmlparse instance has no attribute 'findadress'

And findadress function is spelled correctly in the main, but for some reason what so ever i am getting this error.

Any help is really appreciated.

And I also wanted to know, how can I validate the xml with an XSD schema in python?

“self = minidom.parse(xmlfile)” overwrites the Xmlparse object you just created. You want to assign the xml doc to a variable instead:

from xml.dom import minidom
from copy import copy

class Xmlparse:

    def __init__(self, xmlfile):
        self.doc = minidom.parse(xmlfile)

    def findadress(self):
        itemlist =self.doc.getElementsByTagName('addresses')
        return itemlist[0].attributes['firstname'].value
