Re: cannot find an html parser in Jython

[Aaron DeVore]

Just don't pass in a parser argument. Beautiful Soup will automatically pick one that it prefers.

I'm trying to use BeautifulSoup 4.1.3 with Jython (I'm using Jython 2.7beta1, since the stable release corresponds to cPython 2.5).

As part of my upgrade of BeautifulSoup from 3 to 4, I see I need to install a parser. And since I'm using jython, I need to install one with no C dependency. 

How do I convince BeautifulSoup to use the native Python html parser? I can't use 'html.parser' because that name is not valid in Python 2.7. I tried HTMLParser and that doesn't work either.

>>> BeautifulSoup.BeautifulSoup(content, 'html.parser')

    raise FeatureNotFound(

BeautifulSoup.FeatureNotFound: Couldn't find a tree builder with the features you requested: html.parser. Do you need to install a parser library?

That pretty much leaves me trying to use html5lib. That won't work either, because inputstream.py in that lib contains some seriously broken Unicode characters in the range 0xD800-0xDFFF, which are known to the trade as "unpaired surrogate". jython cannot read inputstream.py. This has been closed as wont-fix: http://bugs.jython.org/issue1836

I've opened this as an issue with html5lib (https://code.google.com/p/html5lib/issues/detail?id=220)

So I'm back to the native Python html parser - how do I use it in 2.7 without calling it 'html.parser'?

I suppose since it's Jython there should be a way to use a Java-native parser, right?

I don't know if this will help. If Jython doesn't have HTMLParser
there's probably no parser it can use.

However, it's possible there's just a problem _loading_ HTMLParser
from the name 'html.parser'. So try Aaron's suggestion, and if that
doesn't work see what happens when you 'import HTMLParser'.
