can you get at it using the DOM?

or maybe you will ned to use PREG on the relevant section.

I have done similar in cURL using pattern matching to grab the code I wanted.

Download biterscripting from

Code:

http://www.biterscripting.com

. Start biterscripting. Enter the following command.

The entire code below is just one command. Enter the whole command on one line.

Code:

script SS_WebPageToCSV.txt page("http://www.onemotoring.com.sg/publish/onemotoring/en/on_the_roads/traffic_news.html") number(11)

Try it now. This particular script seems to have been written just for you :-) It is open source. I did not write it, but I have been using it and other biter scripts.

Hope this helps. I am assuming you are getting this data only for your personal use and not to republish.
