Using Scrubyt on bad markup pages

Rolin Nelson

4/28/2009 6:39:00 AM

I am having trouble scrubbing a page that has bad markup. After
fetching the page, the Scrubyt::Extractor exits while parsing the
document. The Apple Safari web inspector shows numerous errors from the
page:

<meta> is not allowed inside <td>. Moving <meta> into the <head>.
Unmatched </embed> encountered. Ignoring tag.
Unmatched </span> encountered. Ignoring tag.
Unmatched </a> encountered. Ignoring tag.

Is there anyway to scrub a page with scrubyt that is poorly formated? I
am using the latest version (0.4.1) of scrubyt.

Thanks,
Rolin

switch to mechanize and update your gems. scrubyt depends on hpricot
and a very old version of mechanize. Mechanize now uses nokogiri
instead of hpricot and is much more resilient with errors.

Thank you, I will try to use Mechanize directly. However, when I
installed scrubyt 0.4.1 it did appear to have a dependency on nokogiri.
I've cut and pasted the standard output.

$ sudo gem install scrubyt-0.4.11.gem
