    I'm trying to develop a regex for matching

with preg_match_all, I want to match such things like image name, image alt text, image title in construct like this: ....html... <div class="class" style="style"> <img src="img=name" alt="alt" title="title" /> <span class="class" style="style"> text </span> </div> ....html... The rexex as for now is: define(

       'REGEX_IMAGE_NAMES_AND_TITLES_AND_ALTS_FROM_CONTENT',
       '{
        (?:<\s*img\s+src\s*=\s*(?:"|\')?\s*(?:img)?\s*=\s*)       #  <img>
        (?>\b\S+\b)                                               # name
        (?:title\s*=\s*(?:"|\'))                                  # title
        (?>\b\S*\b)
        (?:"|\')*\s*                                              (?:alt\s*=\s*(?:"|\'))                                    # alt
        (?>\b\S*\b)
        (?:"|\')*\s*                       (?:\"|\'|>|/>|\s)                                         # <img />
        }Uix'
     );

, but it does not match. How can I fix it?

It's not so easy to match an entire IMG tag, because first of all the attributes are not always in the same order. If I were you, this is what I would do : ereg("<img ([^>]+)>", $your_text, $img_array); $i = 0; foreach ($img_array as $img) { while (ereg("^(.+)=\"(.+)\"", "", $img, $regs)) $images[$i][$regs[1]] = $regs[2]; $i++; } Hope this helps,

Sorry I made a mistake. Better do this: ereg("<img ([^>]+)>", $your_text, $img_array); $i = 0; foreach ($img_array as $img) { while (ereg("^(.+)=\"(.+)\"(.+)$", "", $img, $regs)) { $images[$i][$regs[1]] = $regs[2]; $img = $regs[3]; } $i++; } -- Cordialement, --------------------------- Sophie Mattoug Développement web dynamique sophie@mattoug.net ---------------------------
