This is a much faster method to grep the information:

Code:

proc blo {} { set url "http://ns.wireplay.co.uk/hlstats.php?mode=playerinfo&player=55" set token [::http::geturl $url] set content [split [::http::data $token] \n] ::http::cleanup $token if {[set i [lsearch -glob $content {*Kills per Death:*}]]!=-1} {  regexp {\d+\.\d+} [lindex $content [incr i]] value  puts $value }}

Worked fine for me; tested it on tclsh

Code:

proc bla {} { set url "http://ns.wireplay.co.uk/hlstats.php?mode=playerinfo&player=55" set token [::http::geturl $url] set content [::http::data $token] ::http::cleanup $token set notFound 1 foreach line [split $content \n] {  if {$notFound && [regexp {Kills\sper\sDeath:} $line]} {   set notFound 0  } elseif {!$notFound} {   regexp {\d+\.\d+} $line value   puts $value   break  } }}

% package require http
2.5.2
% bla
0.6649

ive attempted to do what you suggested, however it never seems to find the Kill per Deaths:

Im wondering if ive split the file wrong, ive written $::html to a text document, and it comes out exactly as it is in the source. so im not sure why it wouldnt work my code is :

Code:

set notFound 1set lines [split $::html \n]        foreach line $lines {              if {$notFound && [regexp {Kills\sper\sDeath:} $line]} {                  set notFound 0              } elseif {!$notFound} {                  putquick "PRIVMSG $chan : Line $line found"                  regexp {\d+\.\d+} $line value                  putquick "PRIVMSG $chan : Value is $value"                  break             }       }

If you provided code, it would've been easier. The concept is easy, this should explain it:

Code:

# variable $lines is a list containing the html sourceset notFound 1foreach line $lines { if {$notFound && [regexp {Kills\sper\sDeath:} $line]} {  set notFound 0 } elseif {!$notFound} {  regexp {\d+\.\d+} $line value  break }}# $value contains the number.

I think i explained badly, the regexp works on the entire source of the website, not just the two lines i posted, thats the reason i wanted to get the words Kills per Death: so that i was sure it was the right data.

the problem i have is the two seperate lines i dont know how to deal with. but thanks for explaining that regexp. it actually makes sence to me now

Well \d matches any digit, \. matches a period '.' and + (or {1,}) means 1 or more. An alternative regexp you can try is:

Code:

regexp {<.+><.+>(.+)<.+><.+>} {0.6193} grbg value

$value should contain 0.6193.

That gives me a result of 4.01, which im not sure where its getting it from but its not correct.

The entire source that the regexp needs to search through is the source of this page : http://ns.wireplay.co.uk/hlstats.php?mo ... &player=55

if thats any help, i really dont understand that regexp you gave me atall. i stuggle to get my head around it

EDIT :
Ok i found that it match the 4.01 in this line

http://www.w3.org/TR/html4/loose.dtd">

again i dont really have a clue how the regexp works, or id try fixing it myself

Code:

regexp {\d+\.\d+} {0.6193} value

this will store 0.6193 in value.

Hey, im still learning regular expressions, and im pretty much stumped on this one, several people have tried to help me already and its just not right yet, im using a http package to read a website, and then parse for a specific piece of info on that website, the information im after is stored in a table.

The two lines that im looking at are :

Kills per Death:
0.6193

what i need to do, is check that the line before has Kills per Death, and then pull the value from the next line which in this case is 0.6193. there are several sections of the table that are identical appart from the text Kills per Death: hence why i need to check both lines.

i have tried many diffrent regexp to get this working, and all return nothing.

Any help and i would be very greatful.
