It appears that IE renders it's display: none in all caps while Firefox and other browsers pass it back in lowercase. This throws off my php line of code the is supposed to nuke blank bullets from a string of text:
$bl =







  • Reserved Frontstretch Tower Ticket to the NextEra Energy Resources 250 on Friday Night

  • Reserved Frontstretch Tower Ticket to the Camping World 300 on Saturday

  • Reserved Frontstretch Tower Ticket to the Daytona 500 on Sunday














    • I want to keep the "DISPLAY: list-item" lines, and nuke all the others.
    The below above are sent to PHP in a variable called $bl. I then try to nuke the "DISPLAY: none" lines with something like:

    $pattern = '/]*style="display: none[^>]*>/';
    $bl = preg_replace($pattern,'',$bl);

    $pattern = '/]*style="DISPLAY: none[^>]*>/';
    $bl = preg_replace($pattern,'',$bl);

    But it appears that the case-sensitivity fix is not just a matter of making the letter capitals. I'm sure someone who knows more than I about preg_replace will see the
    immediate error of my ways. Any advice is greatly appreciated.

    Your regex is looking for case-sensitive matches, which given the example
    below, would preclude all of your list items (they all start with " "
    Try using a case insensitive regex (e.g., $bl = preg_replace($pattern
    = /]*style="DISPLAY: none[^>]*>/i','',$bl);

    (Note the "i" after the search pattern above.)
