Yes, I believe we've used it with FME before. There used to be an article on the knowledgebase, but it was removed because it became out of date. In case it's of use, the following is the content of that article:

Parsing HTML files with Beautiful Soup for Python

BeautifulSoup for Python is a powerful parser for HTML/XML. It can
serve well as a replacement of the standard FME tools such as
StringSearcher (aka Grepper) or StringReplacer. Their use for HTML
parsing is shown on HTTPFetcher page.

The attached example takes an HTML page containing a few tables.
Some of them are used for design purposes, the other contain useful
information about extra cost plug-ins for FME. BeautifulSoup scans
through them, takes only necessary tables (<table> tags), searches
for rows (<tr> tags) and cells (<td> tags) turning them
accordingly into feature types, features, and attributes.

Then FME itself takes care about exposing and renaming attributes, cleaning and replacing attribute values where necessary.

In order to use BeautifulSoup, Python 2.3 or higher should be installed (find more details here). BeautifulSoup.py
should be placed either into \\Python24\\Lib\\site-packages (to use it
with any workspace) or together with the workspace calling it (to make
it portable).

Note that HTML can have a very complex structure, and it's
impossible to use one Python script for any HTML file. Use this example
as a simple introduction into HTML parsing.

Refer to BeautifulSoup documentation for more details about HTML parsing.

Sadly, the example that is mentioned in the article has also been removed and isn't available. But I hope the above helps in some way

FYI FME 2017 has a couple of transformers/readers that use this package. THere is an HTML Extractor transformer, and a reader that just can read tables and lists from HTML pages. Watch for the beta coming soon...

Hi @mark2catsafe, I was wondering where the article was as. I have been using RegEx to parse the html pages to extract table automatically, need to remove all the unnecessary html tags. Tedious work at the beginning but you get the work done.

Thanks @daleatsafe, will surely keep an eye on the beta !

@mark2catsafe; @daleatsafe just a random thought; wouldn't be great to be able to accept multiple answers on a question here?

Yes, I agree. I've wanted to accept more than one answer in the past too. I'll suggest it.
