#102015 — Question about how to do something in BeautifulSoup?

I hope this is an appropriate mailing list for BeautifulSoup questions,
it's been a long time since I've used python-list and I don't remember if
third-party modules are on topic. I did try posting to the BeautifulSoup
mailing list on Google groups, but I've waited a day or two and my message
hasn't been approved yet.

Say I have the following HTML (I hope this shows up as plain text here
rather than formatting):

<div style="font-size: 20pt;"><span style="color: #000000;"><em><strong>"Is
today the day?"</strong></em></span></div>

And I want to extract the "Is today the day?" part. There are other places
in the document with <em> and <strong>, but this is the only place that
uses color #000000, so I want to extract anything that's within a color
#000000 style, even if it's nested multiple levels deep within that.

- Sometimes the color is defined as RGB(0, 0, 0) and sometimes it's defined
as #000000
- Sometimes the <strong> is within the <em> and sometimes the <em> is
within the <strong>.
- There may be other discrepancies I haven't noticed yet

How can I do this in BeautifulSoup (or is this better done in lxml.html)?
Thanks

I think you'd do better using the pyparsing library
