Question

<li class=""><a href="/admin/reimburse1?ref=addtabs" addtabs="131" url="/admin/reimburse1" py="dwsh" pinyin="danweishenhe"><i class="fa fa-circle-o fa-fw"></i> <span>单位审核</span> <span class="pull-right-container"> </span></a> </li><li class=""><a href="/admin/reimburse?ref=addtabs" addtabs="125" url="/admin/reimburse" py="fybx" pinyin="feiyongbaoxiao"><i class="fa fa-circle-o fa-fw"></i> <span>费用报销</span> <span class="pull-right-container"> </span></a> </li>

需要提取出第一个<li class="">中的内容：

<li class=""><a href="/admin/reimburse1?ref=addtabs" addtabs="131" url="/admin/reimburse1" py="dwsh" pinyin="danweishenhe"><i class="fa fa-circle-o fa-fw"></i> <span>单位审核</span> <span class="pull-right-container"> </span></a> </li>

preg_match_all('/(<li class="">(.*?)<\/li>)/i', $str, $matches, PREG_PATTERN_ORDER);
    echo $matches[1][0];

Answer 1

/(?<=<li class="">)(.*?)(?=</li>)/i
