[asterisk-users] AGI to announce temperature from weather.com XML file

It appears I opened some flood gates when I offered my 'alternative'
version.

So, rather than send hundreds of e-mails out - here's the link :

Any questions - just 'yell'.

Since your problem came up on the VoIP Users Conference today, it ended
up being 
the basis for a blog post I wrote today.

The blog post (which may solve your problem) is available here:

http://leifmadsen.wordpress.com/2009/07/17/howto-read-a-value-from-a-fil
e-and-say-it-back/

Let me know if that works for you -- just respond on the comments
section since 
I don't always check this users list.

Note: I haven't actually tested the dialplan yet, so if someone can test
it for 
errors, let me know if you run into any, and I'll update the blog post
with any 
that may be found.

Thanks!
Leif Madsen.
