selectolax is a fast and lightweight library for parsing HTML and XML documents in Python. It is designed to be a drop-in replacement for the popular BeautifulSoup library, with significantly faster performance.
selectolax uses a Cython-based parser to quickly parse and navigate through HTML and XML documents. It provides a simple and intuitive API for working with the document's structure, similar to BeautifulSoup.
To use selectolax, you first need to install it via pip by running pip install selectolax``.
Once it is installed, you can use theselectolax.html.fromstring()function to parse an HTML document and create a selectolax object.
For example:
selectolax.html.fromstring()from selectolax.parser import HTMLParser
html_string = "<html><body>Hello, World!</body></html>"
root = HTMLParser(html_string).root
print(root.tag) # html
with file-like objects, bytes or file paths,
as well asselectolax.xml.fromstring()`` for parsing XML documents.
Once you have a selectolax object, you can use the select() method to search for elements in the document using CSS selectors,
similar to BeautifulSoup. For example:
body = root.select("body")[0]
print(body.text()) # "Hello, World!"
Like BeautifulSoups find and find_all methods selectolax also supports searching using the search()`` method, which returns the first matching element,
and thesearch_all()`` method, which returns all matching elements.
untangle is a simple library for parsing XML documents in Python. It allows you to access data in an XML file as if it were a Python object, making it easy to work with the data in your code.
To use untangle, you first need to install it via pip by running pip install untangle``.
Once it is installed, you can use theuntangle.parse()`` function to parse an XML file and create a Python object.
For example:
import untangle
obj = untangle.parse("example.xml")
print(obj.root.element.child)
You can also pass a file-like object or a string containing XML data to the untangle.parse() function. Once you have an untangle object, you can access elements in the XML document using dot notation.
You can also access the attributes of an element by using attrib property, eg. `obj.root.element['attrib_name']`` untangle also supports xpath-like syntax to access the elements, obj.root.xpath("path/to/element")
It also supports iteration over the elements using obj.root.element.children
for child in obj.root.element.children:
print(child)
Example Use
from selectolax.parser import HTMLParser
html_string = "<html><body>Hello, World!</body></html>"
root = HTMLParser(html_string).root
print(root.tag) # html
# use css selectors:
body = root.select("body")[0]
print(body.text()) # "Hello, World!"
# find first matching element:
body = root.search("body")
print(body.text()) # "Hello, World!"
# or all matching elements:
html_string = "<html><body><p>paragraph1</p><p>paragraph2</p></body></html>"
root = HTMLParser(html_string).root
for el in root.search_all("p"):
print(el.text())
# will print:
# paragraph 1
# paragraph 2
import untangle
obj = untangle.parse("example.xml")
print(obj.root.element.child)
# access attributes:
print(obj.root.element['attrib_name'])
# use xpath:
element = obj.root.xpath("path/to/element")
