Code: <a href='http://tehclan.com/forum/index.php?showuser=51379' title='11:00 AM'><span style='color:orange'>Ash[numbers]_NM</span></a>, <a href='http://tehclan.com/forum/index.php?showuser=49877' title='10:59 AM'><span style='color:#000000'><img src='http://tehclan.com/forum/rankicons/staff.gif' border='0'/>Egekalaycan</span></a>, <a href='http://tehclan.com/forum/index.php?showuser=19999' title='10:54 AM'><span style='color:#6e2de4'><img src='http://tehclan.com/forum/rankicons/staff.gif' border='0'/>Ash44455666</span></a>, <a href='http://tehclan.com/forum/index.php?showuser=44984' title='11:00 AM'><span style='color:#4C7FB1'>Rikieman1</span></a>, <a href='http://tehclan.com/forum/index.php?showuser=50689' title='11:00 AM'><span style='color:#4C7FB1'>Killharry1</span></a>, <a href='http://tehclan.com/forum/index.php?showuser=24641' title='10:49 AM'><span style='color:#4C7FB1'>jaguar838</span></a>, MSN.com<br /><br /> I thought it wouldn't be too much of an issue; I wrote up this regular expression to get the information I need when those particular lines arrive (by the way, the number of the lines is never (guaranteed to be) the same, and the names will (usually) be different). Code: \d+? (?:AM\|PM)'>(.+?)<\/a> And so, when the line arrives, I would get everything between the end of the <a> tag to the </a> tag, then I would remove the remaining html using an alias I got from the net. Thing is, it doesn't work at all, and every single variation of it that I could think of hasn't worked. In fact, this is the most recent "version" of it, whereas the original was much more complex, so much so that I wouldn't have needed any post-editing to have the name I want. Thanks in advance; I've managed to accomplish so much to this point without actually getting any assistance (learning via google searches and this webpage), I can't believe I can't get something this simple to work. >.< Also, since it may come in handy to others, I use this site to help me write regular expressions. I also learned a bunch from it. It isn't perfect in regards to mIRC Scripting, but it really helps nonetheless. http://gskinner.com/RegExr/

Code: alias regtest { var %text = <a href='http://tehclan.com/forum/index.php?showuser=19999' title='10:54 AM'><span style='color:#6e2de4'><img src='http://tehclan.com/forum/rankicons/staff.gif' border='0'/>Ash44455666</span></a>, var %regex = \d+? (?:AM\|PM)'>(.+?)<\/a> if ($regex(%text,%regex)) { echo -a Match: $regml(1) } } ...works for me with your example lines. So does: var %regex = /\d{2}:\d{2} [AP]M'>(.+?)<\/a>/ var %regex = /<a href=\S+ title='\d{2}:\d{2} [AP]M'>(.+?)<\/a>/ etc (I don't know how "exclusive" matching has to be. The simplier the better).

Code: if (%gActiveMembers == true) { if ($regex(%tmp,/\d{2}:\d{2} [AP]M'>(.+?)<\/a>/)) { aline @tehclan Got Active Member: $htmlfree($regml(1)) } } A previous if statement of similar case was for the variable "%gActiveMembersTypes". Problem was, in that same if statement (it was using regex as well to find how many guests, members, and anon members were connected), it was setting "%gActiveMembers" to false instead of "%gActiveMembersTypes". Idiot error, as usual. In any case, thanks a lot for the help; I normally catch these kinds of stupid mistakes before considering asking for help, but regardless, it's working now. Oh, and for the sake of searches, here's the $htmlfree alias I have. Code: alias -l htmlfree { ; It's local because it won't be used by the command line, only this file. ; Local aliases avoid conflicting names. var %x, %i = $regsub($1-,/(^[^<]>\|<[^>]>\|<[^>]*$)/g,$null,%x), %x = $remove(%x, ) return %x }
