Get NSString from text on HTML page?

[mriphoneman]

Hi folks,

I'm working on an app that would require me to get some text from a webpage and copy it into a NSString. The text will always be enclosed in the same HTML tag on the site. Is what I want to do possible? Is so, could you possibly point me in the right direction?

Thanks in advance.

Merry Christmas!

Couldn't be simpler, if I understood your question correctly:

NSString *string = [[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://www.apple.com/"]];

Awesome, I rigged that up to a textview and that worked great.

Do you possibly know how I would "find" that specific HTML tag in the NSString and then delete everything else?

Imagine a gas price app. The price of gas is embedded in someone's site, and I need to get just the gas price into my app, if that makes sense.

Thanks!

In my app using a UIWebView, I'm able to grab the page title: <title>Title Here</title> as Title Here using DOM.

DOM is used in PHP, Javascript, Java, many other languages; not to mention Objective-C.

NSString *title = [webView stringByEvaluatingJavaScriptFromString:@"document. title"];
(please note the forum puts a space in document.title ...odd)
Take a look at the following link.

Note that this uses a UIWebview solution:

NSScanner is the easiest way to search for something in a string. I'm not at my computer, but if you look it up, you'll find code to search for a pattern, and record what comes after. So you could search for "gas price" and the store the actual price found.
