asterisk users - Jul 2009 - AGI to announce temperature from weather.com XML file

I would like to have the ability to have Asterisk announce the temperature
-- not using TTS -- within the dialplan.  

For a non-Asterisk project, I have a cron job that periodically pulls down
an XML file from weather.com containing local weather data (TWC's user
agreement requires that data be cached locally).  Using sed, I also create a
text file that contains only the numeric value of the current temperature,
created from that XML file (e.g. <tmp>65</tmp> in the XML file
becomes a
text file with 65 as its only contents).  

I am hoping someone on the list has an example of a lightweight AGI script
that I may modify to either read the simple text file and set a dialplan
variable to the current temperature, or hopefully a more-sophisticated one
which will parse the XML file to set the dialplan variable.  

The end goal is to have Asterisk play the speech files "temperature"
"sixty"
"five" "degrees" or the equivalent non-English files per the
channel's
current language setting.  

Thank you.  Any assistance will be greatly appreciated.  

Sincerely,
Trevor Hammonds

Check this one out.
developed for AstLinux, it ought to be close to what you want.
depending on your version, you may need to modify sound file references

I think that the 'FILE' function will do what you're looking for.

Chapter 9 of "Asterisk: The Future of Telephony" shows you how to
build
an AGI script to do just that.  For a free download, check out
www.asteriskdocs.org.  

There are obviously many other ways to do it.

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-file-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!

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'.
