Summary
Mechanizeは、HTML (Content-Type: text/html) をパースする際にMechanize::Pageを利用する。
しかし、パースするHTMLがwell-formedではない場合、パースに失敗する。
Mechanize::Page で処理
require 'mechanize'
agent = Mechanize.new
agent.pluggable_parser['text/html'] = PlainFile
page = agent.get("http://example.com/")
p page
#<Mechanize::Page
{url #<URI::HTTP http://ill-formed.com/>}
{meta_refresh}
{title "ill-formed.com"}
{iframes}
{frames}
{links}
{forms}>
Plain Textで処理
require 'mechanize'
class PlainFile < Mechanize::File; end
agent = Mechanize.new
agent.pluggable_parser['text/html'] = PlainFile
page = agent.get("http://example.com/")
p page
#<PlainFile:0x00007fb8d2077910
