今天編ZBlog上傳模塊的時候,需要用到一個提取文章中文件名的子程,開始我把問題想復雜了,匹配了所有可能的文件名,不僅正則表達式寫了一大串,而且下面還Split了半天,後來我突然發現Z-Blog的上傳文件都存在upload下,白寫了那麼多復雜的匹配。。。哎,不能浪費掉啊,還是貼上來萬一哪個兄弟以後需要也好拿去用~~
下面這段子程基本上可以算是比較不錯的通用匹配了。(PS:我突然發現CODE_LITE把我的UBB轉義了!!!暈,我只好自己轉義了。。。)

實際上,Z-Blog的話就匹配Upload就可以了(但是我為了省事,也為了更精確些,就干脆在上面的那個匹配上面加上了upload,所以看上去好像下面這個更復雜些,其實理論上應該下面這個簡單些,畢竟有upload管著呢。。),也不用SPLit那個/.這麼寫就可以了:

Set Matches = objRegExp.Execute("[img]2312.jpg[/img][img]2312.jpg[/img]hh[img]http://www.dc9.cn/cm/upload/2ed312.jpg[/img]<a href=""http://www.dc9.cn/ddd.jpg""></a> href=""[IMG_RIGHT=400,300,title]upload/2assas.jpg[/IMG_RIGHT]
