General Nokogiri problem

Hello,

On several sites(probably malformed HTML/JavaScript/XML/general parsing
hell) I have the following problem.

For ex:

[email protected]:~/ruby$ irb
irb(main):001:0> [‘rubygems’,‘nokogiri’,‘hpricot’,‘open-uri’].each { |r|
require r }
=> [“rubygems”, “nokogiri”, “hpricot”, “open-uri”]
irb(main):002:0> doc=Nokogiri(open(“http://maps.google.com/”))
=> <?xml version="1.0"?>

irb(main):003:0> doc/“a”
=>

Same with Nokogiri.Hpricot:

irb(main):004:0> doc=Nokogiri.Hpricot(open(“http://maps.google.com/”))
=> <?xml version="1.0"?>

However with regular Hpricot:

irb(main):009:0> (Hpricot(open(“http://maps.google.com/"))/"a”).size
=> 53
(the full post of course is too long, so just showed something simpler)

Hpricot by itself of course works. I tried looking and there’s not much
by
way of documentation or blogs on something like this.

Any suggestions/explanations will be welcome as I like Nokogiri’s speed
very
much.

I am using:

[email protected]:~/ruby$ gem list --local | grep -i nokogiri
nokogiri (1.2.3)
[email protected]:~/ruby$ ruby --version
ruby 1.8.6 (2008-03-03 patchlevel 114) [i686-linux]

Nokogiri detects the XML header and parses it as XML. If you force it
to use the HTML parser, you may be more successfull:

(Nokogiri::HTML(open(“http://maps.google.com/”))/‘a’).length
=> 53

Thanks Aaron.

Whoops,

irb(main):015:0> (Nokogiri::HTML(open("http://maps.google.com/
"))/‘a’).length
=> 0

Not sure what the deal is.
