I wanted to parse following html tags contents retrieved through curl by regular expressions.

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

so that output will be "IND - 203/9 (49.4 Ovs)".

I have written following code but it is not working.please help.

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

    Try this one:

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

    Dynamic span tag:

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

    Specific span tag:

    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)

    If you simply want to remove the HTML tags, Use the php built-in function strip_tags to remove the html tags.

    Another answer on removing html tags Strip all HTML tags, except allowed

    The problem of your regex is the [.] part. This is matching only a literal ., because the dot is written inside a character class. So just remove the square brackets.

     $five="~(?<=<span class='ui-allscores'>).*(?=</br></span>)~";

    The next problem then is the greediness of *. You can change this matching behaviour by putting a ? behind.

    $five="~(?<=<span class='ui-allscores'>).*?(?=</br></span>)~";

    But the overall point is: You should most probably use a html parser for this job!

    See How do you parse and process HTML/XML in PHP?
