Hello I'm searching for a script, that searches a string on a webpage and posts it on my irc channel.
Example:
www.test.com/test.html looks like this:
| Quote: | <html>
<body>
<h1>Animal Dog</h1>
</body>
</html> |
# How to output the string? (It has to be $startstring)
When I use $text, it doesnt work!
My Starting:
| Code: | package require http
bind pub - !searchstring searchproc
proc searchproc {nick uhost hand chan text} {
set url "www.test.com/test.html"
set token [::http::geturl $url]
set content [::http::data $token]
::http::cleanup $content
regexp {<h1>$startstring(.*?)</h1>.*?} $fullcontent $stringcontent
if {[info exists $startstring]} {putserv "PRIVMSG $chan : String not found"}
else {putserv "PRIVMSG $chan : $stringcontent} } |
So, my problem is how to tell the script to give out the string_search_text.
How can I do that? |

You cant use variables within the regexp like that, although you can use a form like:
| Code: |
set regexvar "h1>$startstring(.*?)</h1>.*?"
regexp $regexvar $content fullcontent stringcontent
|
That should work, assuming $startstring is actually defined (I don't see it defined in your code.)
Note also you made a mistake in using $fullcontent, $stringcontent, instead of just 'fullcontent, stringcontent' in your regexp and you also forgot to put in the $content var.
Actually, now that I look again, your code doesn't make much sense.. The stuff between () in the regexp, is what's going to be captured into $stringcontent. I'm assuming your $startstring is some other content you do *not* want to capture..
If you simply want to capture the entire content between <h1> </h1> then use:
regexp {<h1>(.*?)</h1>} $content fullcontent stringcontent |
