QDomDocumentでtwitterに凸

QDomDocumentのサンプルコードはQDomNode→QDomElementと変換してってコードになっとおけど、QDomElement::firstChild()じゃなくてもQDomElement::firstChildElement()なんて言うそのまんまの名前のものもあったりして。こりゃ使うっきゃない。どうしてもだらだらしがちだしね。

以前のQOAuth周りでゲットできたXMLをざざざーっと適当な構造体配列に突っ込む感じで。

ぶっちゃけOAuth経由でアクセスできて、XMLが取得さえできてしまえばあとは正直どうとでもなる。適当にメモリ上に格納できてしまえばあとは煮るなり焼くなり好きにした上でUIでもつけりゃtwitterクライアントのできあがり。まあ、投稿部分スルーしてるけどね。

以前上げたQOAuthのんと組み合わせれば簡単なコマンドライン型クライアントとかならさくっと作れるんじゃないでしょうか。俺は作りませんけどね。

しかしtwitterの吐くXML、status毎にuser情報持ってたりとかしていやに長い。できるだけ一回のアクセスで情報を流すって工夫だとは思うんだけど、RT元とRT自体の情報を１つのstatusが持ってたりとかするのね。いいのか悪いのかは分からんなあ。まあ取り込んで解析さえしてしまえば同じっちゃあそうだけど。

さて。

例によってかいつまむよー。ちょっとだらだら長いよー。
