You need to \escape the period(.) and you need to \escape the question mark(?)

Thanks, mate! This was the right thing. I had to escape the special chars. Now it works!

Half right, half wrong...
. would match any character, and would survive not being escaped.
? however does not match any characters by itself, but is used to match 0 or 1 occurances of the prefixed atom (in this case the character p). In this case it must be escaped.

I don't think that would make much difference, as both . (dot) and ? are wildcard chars, so it should have matched the string.

Is the var $html empty of data? You don't handle any error conditions, so it could be that the data is not being retrieved.

Here is an example of getting html data and handling error conditions, then fishing out the data you want:

Code:

set xeurl "http://www.xe.com/ucc/convert.cgi"set xequery [::http::formatQuery Amount "$amount" From "$fromcur" To "$tocur"]catch {set page [::http::geturl $xeurl -query $xequery -timeout $xeutimeout]} errorif {[string match -nocase "*couldn't open socket*" $error]} {        puthelp "PRIVMSG $nick :Error: couldn't connect to XE.com..Try again later"        ::http::cleanup $page        return}if { [::http::status $page] == "timeout" } {        puthelp "PRIVMSG $nick :Error: Connection timed out to XE.com."        ::http::cleanup $page        return}set html [::http::data $page]::http::cleanup $pageif {[regexp {>Live rates at (.*?)} $html match xetime]} {        #some of the IF above has been deleted for this example        # manipulate the data:        regsub -all {} $fromamount {} fromamount        regsub -all {} $toamount {} toamount        puthelp "PRIVMSG $chan :XE.COM: \002$fromamount\002 equals \002$toamount\002 as of $xetime"} else {        puthelp "PRIVMSG $chan :Could not obtain results from XE.com, sorry!"}

Code:

regexp {'/profile/index.php?profile_id=(.*?)'} $html fullmatch exactmatch

Code:

regexp {'/profile/index\.php\?profile_id=(.*?)'} $html fullmatch exactmatch

You need to \escape the period(.) and you need to \escape the question mark(?)

Hm, $exactmatch is empty after doing this.

My proc looks this like:

Code:

proc poloniaflirt::internalCom { suche } {  set fullmatch ""  set exactmatch ""  set log1 [open pf.txt a]  set log2 [open reg.txt a]  set pfsearchurl "http://www.polonia-flirt.de/search/index.php"  set pfquery [::http::formatQuery sea_nickname "$suche" send "send"]  set page [http::config -useragent "Mozilla/4.0 (compatible\; MSIE 6.0\; Windows NT 5.0)"]  set page [::http::geturl $pfsearchurl -query $pfquery -timeout $poloniaflirt::pftimeout]  set html [::http::data $page]  puts $log1 "$html"  close $log1  regexp {'/profile/index.php?profile_id=(.*?)'} $html fullmatch exactmatch  puts $log2 "$exactmatch"  close $log2  return $page}

Assuming the data is in a var called $html:

Code:

regexp {'/profile/index.php?profile_id=(.*?)'} $html fullmatch exactmatch# the data you want will be in $exactmatch var.
