Code:

# Script to grab titles from webpages

# Detects URL from IRC channels and prints out the title
#
# Version Log:
# 0.11 Updated regex parser to only parse titles inside <head> tags
# Added HTTP error status logging
# 0.10 Fixed XPath parsing error and added regex fallback if XPath fails
# 0.09 HTTPs redirects, case-insensitive HTTP header fix, other small bug fixes
# 0.08 Changed putserv to puthelp to queue the messages
# 0.07 Added Content-Type check (text/html only) and exceptino handling for tDom with a fallback to
# regexp if tDom fails.

# 0.05 Added SNI support for TLS (with TLS version check)
# 0.04 HTML parsing for titles added

# Original script:
# Copyright C.Leonhardt (rosc2112 at yahoo com) Aug.11.2007
# http://members.dandy.net/~fbn/urltitle.tcl.txt
# Loosely based on the tinyurl script by Jer and other bits and pieces of my own..
#
################################################################################################################
#
# Usage:
#
# 1) Set the configs below
# 2) .chanset #channelname +urltitle ;# enable script
# 3) .chanset #channelname +logurltitle ;# enable logging
# Then just input a url in channel and the script will retrieve the title from the corresponding page.
