求个简单的PHP正则匹配。
<ul class="main_con"> <li> <span class="kind"><a href="http://book.zongheng.com/store/c21/c1210/b9/u0/p1/v9/s9/t0/ALL.html" title="动漫同人" target="_blank">[动漫同人]</a></span> <span class="chap"> <a href="http://book.zongheng.com/book/299149.html" class="fs14" title="宠物小精灵黑白2" target="_blank">宠物小精灵黑...</a> <a href="http://book.zongheng.com/chapter/299149/5188596.html" title="正文 第二十二章 暗涌！" target="_blank">正文 第二十二...</a> </span> <span class="number"> 2826/18/0 </span> <span class="author"><a href="http://home.zongheng.com/show/userInfo/10996625.html" title="一鼎" target="_blank">一鼎</a></span> <span class="time">13-08-29 14:55</span> </li> <li> <span class="kind"><a href="http://book.zongheng.com/store/c31/c3106/b9/u0/p1/v9/s9/t0/ALL.html" title="青春校园" target="_blank">[青春校园]</a></span> <span class="chap"> <a href="http://www.mmzh.com/book/280776.html" class="fs14" title="那年雪花在飘，谁在忧伤？" target="_blank">那年雪花在飘...</a> <a href="http://book.zongheng.com/chapter/280776/5188594.html" title="正文 真诚璃茉与夜落雪的暗斗" target="_blank">正文 真诚璃茉...</a> </span> <span class="number"> 202/5/0 </span> <span class="author"><a href="http://home.zongheng.com/show/userInfo/9854181.html" title="蕾娜莎" target="_blank">蕾娜莎</a></span> <span class="time">13-08-29 14:55</span> </li>
以上代码中我只想要(.*)和这个格式一样的URL。这正则怎么写。
以下是我写的，
$html=file_get_contents($setting['book_url']);
$k='/
- ';
-

$k.='(.*)(.*)<\/a>(.*)';
$k.='<\/ul>/isU';
preg_match_all($k,$html,$rs);
没有匹配到地址
回复讨论(解决方案)
preg_match_all('#(.*?)<\/a>#i',$html,$rs);
那直接写就是了
#(.*)#
<ul class="main_con"> <li> <span class="kind"><a href="http://book.zongheng.com/store/c21/c1210/b9/u0/p1/v9/s9/t0/ALL.html" title="动漫同人" target="_blank">[动漫同人]</a></span> <span class="chap"> <a href="http://book.zongheng.com/book/299149.html" class="fs14" title="宠物小精灵黑白2" target="_blank">宠物小精灵黑...</a> <a href="http://book.zongheng.com/chapter/299149/5188596.html" title="正文 第二十二章 暗涌！" target="_blank">正文 第二十二...</a> </span> <span class="number"> 2826/18/0 </span> <span class="author"><a href="http://home.zongheng.com/show/userInfo/10996625.html" title="一鼎" target="_blank">一鼎</a></span> <span class="time">13-08-29 14:55</span> </li> <li> <span class="kind"><a href="http://book.zongheng.com/store/c31/c3106/b9/u0/p1/v9/s9/t0/ALL.html" title="青春校园" target="_blank">[青春校园]</a></span> <span class="chap"> <a href="http://www.mmzh.com/book/280776.html" class="fs14" title="那年雪花在飘，谁在忧伤？" target="_blank">那年雪花在飘...</a> <a href="http://book.zongheng.com/chapter/280776/5188594.html" title="正文 真诚璃茉与夜落雪的暗斗" target="_blank">正文 真诚璃茉...</a> </span> <span class="number"> 202/5/0 </span> <span class="author"><a href="http://home.zongheng.com/show/userInfo/9854181.html" title="蕾娜莎" target="_blank">蕾娜莎</a></span> <span class="time">13-08-29 14:55</span> </li>
以上代码中我只想要(.*)和这个格式一样的URL。这正则怎么写。
以下是我写的，
$html=file_get_contents($setting['book_url']);
$k='/
- ';
$k.='(.*)(.*)(.*)';
$k.='/isU';
preg_match_all($k,$html,$rs);
没有匹配到地址
那是当然啦你的正则表达式是‘/
- (.*)(.*)(.*)/isU’
- 之后的.*不匹配换行符，而html代码中
- 后面有若干空格还有换行符
要是你想获取class="main_con"的ul里面的 的话建议你用jquery处理，它提供了多种选择器，类选择器，属性选择器...
test.php
$str=
html;
$pattern="/
preg_match_all($pattern,$str,$matches);
var_dump($matches[1]);
?>
$matches[1]就是你要的url数组
