Python Lxml
lxml is a library for processing XML and HTML in Python. It is interface-compatible with standard Python libraries like ElementTree and minidom, but it’s implemented in C and therefore much more efficient.
Here’s a simple example of using lxml:
from lxml import etree
# parse an xml file
root = etree.parse('your_file.xml')
# get and print the root element tag
print(root.tag)
# iterate over child elements
for child in root:
print(child.tag, child.attrib)
# search for elements with a particular tag
for elem in root.iter('tag_you_want'):
print(elem.text)
You can also create XML using lxml:
from lxml import etree
# create the root element
root = etree.Element('root')
# add child elements
child1 = etree.SubElement(root, 'child1')
child2 = etree.SubElement(root, 'child2')
child3 = etree.SubElement(root, 'child3')
# add text to an element
child1.text = 'Text for child 1'
# convert the tree to a string
output = etree.tostring(root, pretty_print=True)
print(output)
The lxml library also includes support for searching XML trees with XPath and XSLT transformations. It can also parse and create HTML.
To install lxml, you can use pip:
pip install lxml
However, please note that lxml has dependencies on libxml2 and libxslt, which are written in C. They’re usually installed by default on Linux systems, but on Windows you might need to install them separately.
