Can you fix this pm :) Can't Post

Hello,

I am using an infobot version for IRC that uses modules - (pm's) on a windows XP box using strawberry perl. Here is the version I am using... http://flooterbuck.sourceforge.net/ . I have it working pretty well except I would like to be able to use the weather pm to access http://www.wunderground.com/ instead of http://weather.noaa.gov/weather/current/.

Back in the early 90's I could setup perl programs on unix servers but I have been out of the loop since Bill Clinton left office. I would greatly appreciate it if someone with a younger mind than I have could help me out getting this pm to work.

Here is a sample of what it does now using NOAA. Sometimes it display's all the info and sometimes it misses a little of the information at the end of the line.

[9:44pm] <Seaboard> weather pbi
[9:44pm] <jutroh> PALM BEACH INTERNATIONAL, FL, United States ; Conditions at; last updated: Conditions at; Dew Point: 73.9 F (23.3 C); Pressure (altimeter): 29.94 in. Hg (1013 hPa); Relative Humidity: 84%; Sky conditions: overcast; Temperature: 79.0 F (26.1 C); Visibility: 10 mile(s); Wind: Calm

NOAA has changed there html pages for u.s. weather, so the weather pm can't read the location in the same way as it does for international weather.

[9:49pm] <Seaboard> weather cybr
[9:49pm] <jutroh> Brandon, Man., Canada ; (CYBR) 49-55N 099-57W 409M; last updated: Sep 26, 2011 09:00 PM EDT; Dew Point: 44 F (7 C); Pressure (altimeter): 29.84 in. Hg (1010 hPa); Relative Humidity: 42%; Sky conditions: mostly cloudy; Temperature: 68 F (20 C); Visibility: 15 mile(s); Wind: from the S (190 degrees) at 16 MPH (14 KT)

If its allot of trouble to get it to work for wunderground... noaa would be fine if one of you can fix it :)

Here is the weather.pm that I am using:
