以上代码中我只想要<a href="(.*)" class="fs14" title="(.*)" target="_blank">(.*)</a>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='/<ul class="main_con">';
$k.='(.*)<a href="http:\/\/book.zongheng.com\/book\/(.*)" class(.*)>(.*)<\/a>(.*)';
$k.='<\/ul>/isU';
preg_match_all($k,$html,$rs);
没有匹配到地址
[解决办法]preg_match_all('#<a href="(.*?)" class="fs14" title="(.*?)" target="_blank">(.*?)<\/a>#i',$html,$rs);
[解决办法]那直接写就是了
#<a href="(.*)" class="fs14" title="(.*)" target="_blank">(.*)</a>#
[解决办法]那是当然啦你的正则表达式是‘/<ul class="main_con">(.*)<a href="http:\/\/book.zongheng.com\/book\/(.*)" class(.*)>(.*)<\/a>(.*)<\/ul>/isU’
<ul class="main_con">之后的.*不匹配换行符，而html代码中<ul class="main_con">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<a> </a>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...
[解决办法]test.php
<?php
$str=<<<html
<ul class="main_con">
<li>
