通过xmltodict在python中解析xml文件

Question

I am using xmltodict library in python ( https://pypi.org/project/xmltodict/ ) to parse a xml file by:

import xmltodict
with open("MyXML.xml") as MyXML:
    doc = xmltodict.parse(MyXML.read())

The xml file looks good but I get this error:

ExpatError: no element found: line 1, column 0

What should I do?

Answer 1

In my uses of xmltodict, I have always parsed a string and to get an xml string is use etree. Try this:

import xml.etree.ElementTree as ET
import xmltodict

tree = ET.parse("MyXml.xml")
root = tree.getroot()
data = xmltodict.parse(ET.toString(root))

if you have your MyXml.xml file in a different locatin than this file you will need to handle that using file and the import os.

Good Luck, Hope this helps.
