Parsel is a library build to extract data from XML/HTML documents with XPath and CSS selectors support, and could be combined with regular expressions. It's usees lxml parser under the hood by default.

lazy and fast .mpd file parser - for video streaming
So, now that I no longer work in that industry, and I had some free time, I created a lazy parsing package using lxml instead of the xml parser in the standard library, which can help people who want to have a python only parsing solution.

Parsing XML file deletes whitespace. How to avoid it?
I got curious about this now so I did some tests on my own, and it appears that the XML parser implementation in Python does indeed strip all newline characters from attributes. Whether this is according to XML standard I do not know; I also briefly tried an alternative XML implementation for Python and it behaves the same, so I would assume that this is standard behavior, but I'm not knowledgable enough about XML to say for certain.

Use case for ETL over ELT?
I use lxml for the XML parsing and pyodbc as the ODBC library. We have a small team so I just keep it as simple as possible: 1. A cursor yields the XML documents from a SQL query as a stream 2. A generator function parses the XML document and yields the rows (you could parallelize this step) 3. Stream each of the resulting rows to a single CSV file 4. Scoop up the resulting CSV file into the target database (usually with the DB engine's loader; bulk insert isn't so fast over ODBC) It ends up being a straight forward, low-overhead approach.

How do i go about building a vidoe conferencing app?
Generally, I'm already using Python to glue together things like OpenCV or libxml, which do the heavy-lifting, and taking advantage of how things like Qt's QImage release Python's Global Interpreter Lock, allowing me to load and process images on a background thread, so the Python code itself is usually already I/O-bound, but yes. If the Python code would become a bottleneck, it helps with that too.

Where to start: Learning Web-scraping
lxml is an XML parser however, it also supports HTML parsing. It's blazing fast and supports XPath. I think it isn't as beginner friendly to use, though it has detailed documentation. It works less well with heavily broken HTML documents and the encoding detection isn't as good as the one of BS4.

Python is better than C they said
According to lxml benchmarking docs, Python’s built in xml parser wouldn’t behave that bad either: https://github.com/lxml/lxml/blob/master/doc/performance.txt

Why are circular dependencies even a thing?
Easier example...sphinx is a document generator for python programs (creating docs for the API of programs from source-code comments for example). Spinx depends on html5lib which itself again depends on six...want to make a guess what six uses to generate its API docs? ;) So if you want the api docs of six you will have to first install it without to be able to get a working sphinx install then redo the six on including the building of the API docs.
What are some alternatives?
When comparing lxml and html5lib you can also consider the following projects:
xmltodict - Python module that makes working with XML feel like you are working with JSON
untangle - Converts XML to Python objects
selectolax - Python binding to Modest and Lexbor engines (fast HTML5 parser with CSS selectors).
pyquery - A jquery-like library for python
bleach - Bleach is an allowed-list-based HTML sanitizing library that escapes or strips markup and attributes
rust-cpython - Rust <-> Python bindings
xhtml2pdf - A library for converting HTML into PDFs using ReportLab
gazpacho - 🥫 The simple, fast, and modern web scraping library
