    Wrong Pattern for match_count function

    Hi all there,

    Sorry for this newbee question but how comes that the following
    pattern: $r = "%<td valign=top><a href=\"([^>]+?)\"(.*?)>%";

    does not return any result, while the pattern:
    $r = "%<a href=\"([^>]+?)\"(.*?)>%";

    returns me results, but too many (that's why I wanted to use the first
    pattern, without any luck).

    Called function: $match_count = preg_match_all ($r, $pdata, $items);

    Example of $pdata:
    <td width=80 align=center valign=top><a href="<link that should not be
    grabbed by the pattern>" id=r><img src=image.jpg width=66 height=79
    alt="" border=1><br><f ont size=-2>Bla Bla text</font></a></td><td
    valign=top><a href="<link that should be grabbed by the pattern>"
    id=r>Bla bla text</a><br>

    Can Anyone help, please?

    Thanks.
    Fabian

      ^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^ ^^^^^^^
      How should this match against "<td valign=top>"? You may try the correct
      <td> line or something like (untested)
      %<td[^>]*><a href=\"([^>]+?)\"(.*?)>% as pattern.

          Thanks for your reply Stefan,

          How should it not? Sorry, I am probably wrong, but I am not familiar
          with regexp and reading the rules...does not help me, in this case

          I need to distinguish this string:
          "<td valign=top><a href...." by this one
          "<td width=80 align=center valign=top><a href...."

          I need to match the first and not the second.

          You may try the correct[color=blue]
          > <td> line or something like (untested)
          > %<td[^>]*><a href=\"([^>]+?)\"(.*?)>% as pattern.[/color]

          BTW, this does not match any pattern at all. (why? shouldn't it return
          any "<td...><a href...>" pattern? it's not what I want, however....)

          If you could clarify. Many thanks.
          Cheers,
          Fabian

              Oh sorry my fault. I don't read you $pdata exactly. Is $pdata a exactly
              copy or is it possible that there are any whitespace or somethingelse
              you may forgot?

                  It should be the exact copy of what it should be, however I hope to be
                  able to add any whitespace information: "\s+" if this would be the
                  case.

                  Thanks for your help.
