Hey guys,

First time on the forums but spent a lot of time on #MSL on the IRC network. Great channel!

Here's the HTML as its seen from the page. (Please note the spaces prefixing the actual text on Line 4 before '>English').

Code:

<h4 class="inline">Language:</h4>

<a    onclick="(new Image()).src='/rg/tt-details/language-1/images/b.gif?link=%2Flanguage%2Fen';"     href="/language/en"   itemprop="inLanguage"
    >English</a>
</div>

Here's the mIRC code I have.. that's not matching..

Code:

if ($bfind(&g,1,<h4 class="inline">Language:).text > 0) {
  if ($regex(language,$bvar(&g,1,$bvar(&g,0)).text,/<a\s\s?\s?\s?onclick="\(new Image\(\)\).src='/.+?/.+?/language.?.?/images?/..gif\x3Flink=.+?'\x3B"\s\s?\s?\s?\s?href="/language/.+?"\s\s?\s?itemprop="inLanguage".+\s*(\r\n)>(.*?)</a>/ig) > 0) {
    var %numberoflanguages = $regml(language,0)
    var %languagenumber = 1
    while (%numberoflanguages >= %languagenumber) {
      set %_imdb.movielanguage $iif(%_imdb.movielanguage == $null,$imdbcode($regml(language,%languagenumber)),%_imdb.movielanguage $+ $chr(124) $+ $imdbcode($regml(language,%languagenumber)))
      inc %languagenumber
    }
  }
}

Instead of the (\r\n) .... I've tried [\r\n]* .. no dice either.

Hopefully I'm able to get some help here.

Thank you very much

You are not escaping your slash and since it's what you use to delimit the pattern, the first non escaped slash is probably used as the end of the pattern with the rest being switches. I also think you have a problem around your \r\n, after the quote, there is nothing to match before the newline, but you used the + quantifier with the dot which requires at least one match, in general you should try to reduce the pattern and see if it matches, then extend the pattern to fit your needs etc etc. Note: You are not escaping some dot in your pattern, it's not a problem since a dot match any character including a litteral dot but still, I thought I would mention that. You also don't need to use the hexa form of a ';' Last edited by Wims; 11/01/12 03:54 AM. #mircscripting @ irc.swiftirc.net == the best mIRC help channel

You also have ".+" after the last attribute when there is no extra data prior to the newline in your pasted example. I don't think this is a problem with the binvar stuff, I think it's a problem with your regex. Test that your regex matches the input if you pass it in manually (manually set a bvar with /bset or /bread from a file with sample data and verify). As a sidenote, the server might return only \n in a newline, so your regex should have \r?\n, not \r\n. - argv[0] on EFnet #mIRC - "Life is a pointer to an integer without a cast"
