So I'm trying to parse school's website for some info. I'm trying to get some values using xpath. So I found a html 5 parser and it can't properly parse the first line. Then I figure you it's actually XHTML and not HTML. After quick Google search I found out XHTML can be properly parsed using any XML parser and so I found one and... It can't parse the first line. So I ask LLama3.1 (like a real programmer) why I can't parse the first line with any parser. It explained so nicely that I did not destroy my keyboard when I was told that this document is "XHTML 1.0 Transitional" and it's a mix of HTML 4 and XHTML and can't be parsed with HTML nor XML parser. I hate the guy that invented that so much...

So I can't find a crate to parse XHTML 1.0 transitional? Or a crate to convert xhtml to something else? Any advice?

I wish I could be more help. My advice is you need a better grade of general purpose HTML parsing library, possibly even a browser emulator, rather than a lib specifically for XHTML 1.0 transitional or a converter.

In my Python web automation course in college we used BeautifulSoup and I think maybe mechanize. I think either of those would probably be robust enough to do what you’re trying to do, but if it has to be Rust I’m not sure what’s out there. Otherwise you could upgrade to Selenium or something.

Or if you’re trying to do something fairly simple and you don’t need to parse the whole thing but it’s still a little too complex for plain old regular expressions, you might be able to build a simple parser with the rust pest crate, but of course I would absolutely not recommend trying to build your own full-featured XHTML parser.
