我要匹配

  • 第一章 地府
  • 这种的,也就是要匹配所有章节地址,但我写的是
  • (.*)

  • 结果匹配时也会把前面的
    <li><a href="/wudongqiankun/" class="playpic"><img  src="/static/imghwm/default1.png"  data-src="/bookpic/3/3710.jpg"  class="lazy"   / alt="一个简单的正则匹配问题" ></a><p class="mov-title"><a href="/wudongqiankun/">武动乾坤</a></p></li><li><a href="/zhumataixingce/" class="playpic"><img  src="/static/imghwm/default1.png"  data-src="/bookpic/3/3709.jpg"  class="lazy"   / alt="一个简单的正则匹配问题" ></a><p class="mov-title"><a href="/zhumataixingce/">驻马太行侧</a></p></li><li><a href="/tianzhubian/" class="playpic"><img  src="/static/imghwm/default1.png"  data-src="/bookpic/3/3660.jpg"  class="lazy"   / alt="一个简单的正则匹配问题" ></a><p class="mov-title"><a href="/tianzhubian/">天珠变</a></p></li><li><a href="/tunshixingkong/" class="playpic"><img  src="/static/imghwm/default1.png"  data-src="/bookpic/3/3658.jpg"  class="lazy"   / alt="一个简单的正则匹配问题" ></a><p class="mov-title"><a href="/tunshixingkong/">吞噬星空
    这段也匹配上了,这个怎么处理一下。

    回复讨论(解决方案)

    用测试工具试了,没问题,不知道楼主是怎么匹配的,最好发些代码出来

    preg_match_all('#<li><a href="([^"]+)" target="_blank">(.*)</a></li>#isU',$s,$m);print_r($m);

    (.*)#U',$s,$m);    print_r($m);?>
         楼主的也能用啊。。。
