Thanks for the info, Your Mother

I've been testing XML::LibXML with various HTML files (our corpus has various sizes) to get some benchmarks, and I must say, it's surprisingly quick (except for really large files, which isn't really relevant in my case), however:

• this is a deal-killer: the HTML must be balanced with nice </x> closing tags (which it's often not in the real world), else it croaks without producing any output (HTML::Parser tolerates this kind of thing).

HTML::Parser soldiers on despite missing tags, etc, and still produces useful output (required in our app).

Some (unscientific) benchmarks:

104KB HTML file processed 100 times (average of 3 runs)
HTML::Parser: ~20s
XML::LibXML: ~13s

371KB HTML file processed 100 times
HTML::Parser: ~51s
XML::LibXML: ~30s

550KB HTML file processed 100 times
HTML::Parser: ~73s
XML::LibXML: ~49s

4.3MB HTML file processed once (silly, but interesting in a huh? kind of way)
HTML::Parser: ~4s
XML::LibXML: ~85s

Conclusion: it looks like XML::LibXML is the way to go. My only concern (the reason preventing me from switching over to XML::LibXML) is how to get it to be tolerant of lazy/broken HTML the way HTML::Parser is.

I've had a gander at XML::LibXML but cannot see how to code it to be real-world HTML tolerant (so I can test how tolerant it is).

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
