Nokogiri
Xpathが早いらしい、REXMLより断然。
ということでHpricotで結構時間がかかってバグを吐いたパースが、瞬時にノーミスで。
1.4.4はruby1.8.7@Tiger/1.9.2@SnowLeopardで動作確認。
Hpricot
ruby 1.9.2/SnowLeopard と、ruby1.8.7/Tigerに入れてみるが、Segmentation Fault@Snow, Bus Error@Tigerを吐く。原因不明･･･→Nokogiriでやってみたら回避。
たとえばこんな感じ。parse.rb:33でどちらもひっかかる。Tigerのほうは詳細なエラーを捕捉できないので不明･･･
