如何用正则表达式解析html标签？

Question

我想通过正则表达式解析通过curl检索的html标签内容.

<span class='ui-allscores'>IND - 203/9 (49.4 Ovs)</span>

这样输出就会"IND - 203/9 (49.4 Ovs)".

我写了下面的代码,但它没有工作.请帮忙.

$one="<span class='ui-allscores'>IND - 203/9 (49.4 Ovs)</span>";
$five="~(?<=<span class='ui-allscores'>)[.]*(?=</br></span>)~";
preg_match_all($five,$one,$ui);
print_r($ui);

Answer 1

试试这个:

$string = "<span class='ui-allscores'>IND - 203/9 (49.4 Ovs)</span>";

动态范围标记:

preg_match('/<span[^>]*>(.*?)<\/span>/si', $string, $matches);

特定范围标记:

preg_match("/<span class='ui-allscores'>(.*?)<\/span>/si", $string, $matches);

// Output
array (size=2)
  0 => string '<span class='ui-allscores'>IND - 203/9 (49.4 Ovs)</span>' (length=56)
  1 => string 'IND - 203/9 (49.4 Ovs)' (length=22)
