PARSING XML FROM WEBPAGE
Jun 22nd, 2006, 1:15am  
Hi,
I am trying to use some weather data to control an applet, for example BBC 5day london forecast.

http://www.mopoke.co.uk/weather/detailed/1769.xml

Is it possible to use proHTML or proXML for this? I have read somewhere that xml file must however reside within the data folder of sketch and not on a remote server. I dont really want to use PHP script running on some server for screen-scrapping and later updating a txt/html that processing could eventually read. Neither i want to use GNU Wget or alike to read remote xml files and update a locate txt/xml which processing then refers.
is there a simpler way to read remote xml?

second question is, even if i copy this xml and put it in data directory it doesnt seem to work.(have a look at the xml link). I only want to get windspeed and visibility data for current day into my processing project. However it seems  that all this information is packed under <discription> tag and is not clearly separated. Any idea, how to go about it?
if windspeed is "17MPH" how do i remove MPH from this information and feed 17 as number into a variable?
Any help | pointers | suggestions would be great.
Thank you in advance.

I tried to open the file and it worked, I was also able to directly open the link from a localy runnig processing sketch.
You can use processings string functions to get the information you need from the description:

Also check the java api for more string functions:

Thank you so much.
Actually i was able to read the XML through proHTML meanwhile and it worked really well directly from the link! - So now i know that this is now a matter of how to get the exact data out of XML and not wheather or not it would work.
I will have a go at it over the weekend.
Thank you once again.
