XML::XPathEngineパッチ
パッチ作った。
- descendantとdescendant-or-selfで出てくる順番がおかしかったのを修正
- (id("1")//*)[1]/@att2 みたいにグルーピングしてるのの中にidがあって外側が@attrなときに実行時例外(Can't locate object method "getElementById" via package "XML::XPathEngine::NodeSet")が出るのの修正
amachangのテストコードはpiを除いて通るようになったけどamachangのテストコードはかっこをつかってるやつが少なくてそのへんでまだ問題が残ってる雰囲気が濃厚だった。 (id("1")//*)[1]/@att2 はいけるんだけど (.//*)[1]/@att2 にすると例外が出た気がする(axis axis_descendant not implemented [Can't locate object method "getChildNodes" via package "XML::XPathEngine::NodeSet")
つくづくテストコードちょう重要だとおもった。
レポートしようとしたらなんかCPANおかしくてできなかったのでここにはっとく。
Fx3がSSLのcertがオレオレだと繋がらなかったときと同じような画面出してて、それに気がつかなくて繋がらなかったんだと思ってただけでした....
