Parsing and converting HTML documents to XML format using Python
In this article, we are going to see how to parse and convert HTML documents to XML format using Python.
It can be done in these ways:

- Using Ixml module.
- Using Beautifulsoup module.
Method 1: Using the Python lxml library
In this approach, we will use Python’s lxml library to parse the HTML document and write it to an encoded string representation of the XML tree.The lxml XML toolkit is a Pythonic binding for the C libraries libxml2 and libxslt. It is unique in that as it combines the speed and XML feature completeness of these libraries with the simplicity of a native Python API, mostly compatible but superior to the well-known ElementTree API.
pip install lxml
We need to provide the path to open the HTML document to read and parse it using the html.fromstring(str) function, returning a single element/document tree. This function parses a document from the given string. This always creates a correct HTML document, which means the parent node is <html>, and there is a body and possibly a head.
htmldoc = html.fromstring(inp.read())
And write the parsed HTML element/document tree to an encoded string representation of its XML tree using the etree.tostring() function.
Html file used: input.
Method 2: Using the BeautifulSoup
In this approach, we will use the BeautifulSoup module to parse the raw HTML document using html.parser and modify the parsed document and write it to an XML file. Provide the path to open the HTML file and read the HTML file and Parse it using BeautifulSoup’s html.parser, returning an object of the parsed document.
