<p>These days, robots are more common than you might think. Consider the Roomba, a programmable robotic vacuum which cleans floors on its own.<br /><br />"We wanted to make something simple that people could use every day," says Helen Greiner, co-founder of iRobot, the company that makes the smart vacuum. "And that\'s what inspired us to build the Roomba." <div class=\'boxout photo230px\'><img src="

想清掉被<div> </div>包含的字
但<div>裡面有時候又會放一些屬性,
我試了好多個php regex還是都失敗, 拜託高手指點
my trial:
preg_replace("/<div[.*]>[.*]<\/div>/i","", $string);
ps. regex好難

1F：→ buganini:[]不是這樣用的 12/30 11:31
2F：→ buganini:/<div.*?>.*?<\/div>/ or /<div[^>]*>.*?<\/div>/ 12/30 11:32
3F：→ buganini:後者效能較好 12/30 11:32
4F：→ tnsshnews:我剛才試過完全沒有任何處理ㄟ....還是一樣在@@ 12/30 13:04
6F：→ tnsshnews:regex只能用try的? 12/30 14:41
7F：→ MOONRAKER:你現在不try就永遠只能用try的。 12/31 11:47
8F：→ MOONRAKER:踹了一下（這點我強調）發現，div後面不加上\s+就match 12/31 11:53
9F：→ MOONRAKER:不到，所以寫成土土的<(div\s+[^>]*)|(div)>.*?<\/div> 12/31 11:54
10F：→ MOONRAKER:…不對，要<((div\s+[^>]*)|(div))>.*?<\/div>才行 12/31 11:55
11F：→ chrisQQ:應該不是說用try的啦… 只是因為你的資料（看起來）很複雜 12/31 14:26
12F：→ chrisQQ:你可以用這個flash先一步一步的把 <div> </div> parse出來 12/31 14:26
13F：→ chrisQQ:在慢慢延伸變化到你想要的。另外，右邊有很多網友提供的 12/31 14:27
14F：→ chrisQQ:regex 可以套用，你可以試試看符不符合你的需求～ 12/31 14:27
15F：→ chrisQQ:不過說到底也是我沒有這麼熟悉regex啦，所以只好用try的QQ 12/31 14:29
16F：推 buganini:我忘了加modifier... 後面的/後面加個s吧 再加個i也可 01/06 19:38
