HTML Codes In URL Grabber

Post by BarGuy »

So Im running the script urltitle 0.11 and I get the following at times with a url is posted:
https://twitter.com/_faizann/status/1157157933223821317
Title: faiz on Twitter: "texted my number neighbor....safe to say i got a new best friend… "

I and REALLY new to eggdrop and ubuntu as well (just started last weekend). I read on another threat about adding something along the lines of "$quot;" " " to a string map line to replace the html code with a space, but this particular script doesn't contain a string map. Can someone help me out with tweaking this script to either remove the html code or make it work properly when it sees an html code. Below is the script Im running .

Code: Select all

# 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.
