XPL Script: Current Melbourne Weather

One of the first things I thought i'd try with XPL is to get some global variables set up.

A good start was some global varialbles to store the current weather. Which will obviously come in handy down the track when I look at HVAC & garden watering systems.

With most XPL development being overseas (UK mainly) - there was nothing specific that i could use.

Anyway I found a script on the XPL Forums which I based this on (only ended up using the concept & a couple of lines - but thanks clinque)

What it does

• Grabs the last weather reading via http from the corresponding city page on The Beurea of Meteorology (ie. Melbourne)
• Locates the first row of readings, and writes values into Globals for Temperature, Wind Direction & Speed, Pressure and Rainfall.
• Sends an OSD message when done (I've got a Slim Devices Squeezebox setup to recieve them)

How to Install it

• Download the script and save it to the scripts folder (or create a new user script and cut & paste the code in)
• Setup globals in XPLHAL Manager
  BOM_CURRENTTEMP
  BOM_WINDDIRECTION
  BOM_WINDSPEED
  BOM_PRESSURE
  BOM_RAIN
• Change the URL if needed (Should work on any of the location observation pages)
• Add "call Weather_Init()" at the end of xPLHal_Load() (in script xplHal_Load.xpl)
• Reload scripts (or restart xplHal) - and the globals should be populated with the current weather & the current temperature should be sent to all OSD devices.
