Opusscript can be used to extract information from XML/RSS feeds.
This pub will get the weather in your area (location, conditions, wind direction and speed and temperature). You can use Zipcodes if you live in the US; city codes that can be found at http://weather.yahoo.com/
If the pub finds a text file named loc.txt in the same folder containing the zip or area code, it will read that.

A few city code examples below

UKXX0209 is Banbury, UK
UKXX0061 is Glasgow, UK
UKXX0085 is London, UK

ASXX0089 is Perth, Aust
ASXX0016 is Brisbane, Aust
ASXX0112 is Sydney, Aust

New Zealand
NZXX0061 -- Palmerston North
NZXX0062 -- Paraparaumu

USNY0996 -- New York
USCA0987 -- San Francisco
USIL0225 -- Chicago
but in the USA it's easier to use your zipcode

Very cool - I love weather gadgets.

Here's the Opus Pro v6 source for the weather pub I posted previously. Basically the script follows these steps.

load the page with "InternetGetData()".

Split the page into lines with "split("\n")" and load each line into an array element.

Search each array element for relevant keywords using "String.contains" then use split again to extract the information required from each line.
I've displayed the original feed page to show how the data looks before it is extracted.
You can see the original feed contains more weather data if you want to extract it.
The principles used in this pub can be used on most RSS/XML feeds to update pubs from the web after publication.

Thanks for sharing the source Paul! Gratefully received.

Cheers, Kurt

Yes, thanks Paul.
Much appreciated.

Ken

WOW! MANY thanks - and a great way to learn more about remote accessing of date.

Many thanks!

Great code, thanks for posting. Nice to see some code pulling in XML feeds.


Thanks.

Hi all
Have been looking at this post and the script (thanks Paul). Not being familiar with XML I found it an excellent resource.
I know that this post is a couple of years old, however, during my travels in understanding this and looking at incorporating it into one of my pubs, found that the p parameter used in the yahoo feed will be replaced with a new w parameter. There will be a corresponding set of different city codes.

I have lifted the below examples from the yahoo page, although the current script still works fine, the script as supplied in the download example will need to be modified to reflect the new url and city code data.

To get the forecast for Yahoo! Headquarters in Sunnyvale, CA, use the WOEID code:
http://weather.yahooapis.com/forecastrss?w=2502265

To get the forecast for New York City, use the WOEID 2459115:
http://weather.yahooapis.com/forecastrss?w=2459115

To get the forecast for Paris, France, use the WOEID 615702:
http://weather.yahooapis.com/forecastrss?w=615702

To get the forecast for Paris, France, with degrees Celsius and other metric units:
