How do you pull information from a website?

**Maheriano** · 10-11-2007, 03:08 PM

For all you guys that create applications which pull gas prices or weather information from certain websites, how do you reference it? I'm guessing you'd have to create and open a stream to the website itself, but how do you reference that specific piece of information from the page? Is there an object identifier or variable you use? I want to be able to auto-log into an online account and get a number from there, like how much money is left in my bank account or something.

No one here is going to tell you how to hack an account of any sort.

If you want to know how to access info hosted on a site, look at their particular method. Some use Web Services, some use an API, etc. Trick is, read.

WTF? Hack what? What are you talking about?
I'm looking for development help here....anyone else?

Well I guess you download the page, then look at the file for what you need.

That's what I do for some of the cameras with the Traffic Cam program.

Yea, depending on what you are using while dictate the specifics, but basically..

open a connection to the website, usually with a socket
send the HTTP GET command to request the webpage

if its something simple you want, then you can search through the data as it downloads for what you are looking for, otherwise, you just save it all to a file so you have the entire page downloaded, then search through there for whatever you want

It must be all those Terrabism syntax errors.

What I'm actually after is a Java application I can run on my Blackberry to pull the monthly data usage from my Telus account upon request. So I'll start off trying what you guys suggested.
