Pyxml

Pure python3 alternative to stdlib xml.etree with HTML support

Install

pip install pyxml3

Advantages

1. The default parser ignores XML Declaration Entities avoiding most if not all XML related vulnerabilities such as The Billion Laughs Attack

2. Our XPATH implementation is much more complete than both xml.etree and even LXML. Additional functions and features are available making it easier to quickly parse complex data structures in a single line.

Examples

Standard Usage:

import pyxml

etree = pyxml.fromstring(b'<p>Hello World!</p>')
for element in etree.iter():
  print(element)

with open('example.xml', 'rb') as f:
  etree = pyxml.fromstring(f)
  print(etree)

Monkey Patch:

import pyxml
pyxml.compat.monkey_patch()

from xml.etree import ElementTree as ET

etree = ET.fromstring('<div><p class="hello world">Hello World!</p></div>')
for element in etree.iter():
  print(element)

print(etree.find('//p[starts-with(lower-case(text()), "hello")]'))

HTML:

import pyxml.html

etree = pyxml.html.fromstring('<div><p>Hello World!</p><br></div>')
for element in etree.iter():
  print(element)

print(etree.find('//p[notempty(text())]'))
