Fetching data from Web page in UIWebView..

[harshit2811]

Hello ,

I am suck with some weird type of requirements. I added one UIWebView in my application. I opened thehttp://www.guidgenerator.com/online-guid-generator.aspx web site in my webview.

This site is useful to generate the GUID (128 bit unique id). just have a look.
when i generate that GUID i want to copy that string in my application.
So is there any way through which i can inspect HTML web page having generated GUID and i stored that in my local database???

pls reply if you are not clear with requirements......

Thanks in advance.

There is certainly a way that you could do what you're asking. Or, you could just use CFUUIDCreate.

Thanks for reply,

Basically i dont want GUID number at all . This is just one example
The real problem i am facing is , if i load any web page in my webview and i want to store some info from that page.

suppose , i open one site xyz.com , i logged in and do some task , site gives me the "TASK ID" by some way on web page . Now i want to store that "TASK ID" in local database of my application.( sqlite) so i can populate list of "TASK ID" (UItableView) user has already done.

Note:
This is not client-server model. I just want to fetch data from web page.

Let me know if you need more info.

OK. So what have you tried so far, and where are you stuck?

Thanks,
Meanwhile i got some tricks to get element value of web page.

What i have done is , I override the web view controller delegate method.

- (void)webViewDidFinishLoadUIWebView *)webView
{
NSString *js_result = [webView
stringByEvaluatingJavaScriptFromString:@"document. getElementById('txtResults').value;"];

This gives me value of text box. Now it works bt still i need some efficient way. Is this method effect performance issue?? Will it fetch large string also like paragraph , custom object etc..???
}

[dljeffery]

When you say you need an efficient way, are you actually seeing performance issues with your current implementation? Because I wouldn't expect you would; it should be perfectly fine.

And yes, you can fetch a paragraph. Or even an entire document's html. But not a custom object, only text. Not sure what you'd do with an actual JavaScript object in Objective-C anyway.

Hi, I think I am trying to do something similar but I'm not sure how to extract certain text.. For example

<tr class=" ">
			<td class="title"><a class="title" href="/forum-replies.cfm?t=1647460">iPhone 4 back scratch? How?</a>
				
				</td>
			<td class="group">&nbsp;</td>
			
			<td class="reps" style="background-color: #eae7e3;">7</td>
			<td class="reads" style="background-color: #e9e5e0;">113</td>
			
			<td class="oldest"><a href="/user/311187"><b>Magic is Might</b></a><br>Today at 5:04 pm</td>

			<td class="newest"><a href="/user/257524"><b>Revelation</b></a><br>10 minutes ago</td>
			
				<td class="goend">
			
				<a href="/forum-replies.cfm?t=1647460&amp;p=-1&amp;#bottom" style="color:silver" title="Jump to last post"><img src="/img/forum/arrow.gif" width="16" height="17" alt="Jump to last post" border="0"></a>
			</td>
		</tr> 
		
		
		<tr class=" ">
			<td class="title"><a class="title" href="/forum-replies.cfm?t=1645673">iPhone 5 - let the rumours begin (Part 2)</a>
				<script type="text/javascript">thread_page_list(1645673,5);</script> 
				</td>

			<td class="group">&nbsp;</td>
			
			<td class="reps" style="background-color: #cebeab;">89</td>
			<td class="reads" style="background-color: #cbb9a4;">1557</td>
			
			<td class="oldest"><a href="/user/26479"><b>-DrD-</b></a><br>Tuesday at 3:26 am</td>
			<td class="newest"><a href="/user/92131"><b>Goliath Manhood</b></a><br>11 minutes ago</td>
			
				<td class="goend">

			
				<a href="/forum-replies.cfm?t=1645673&amp;p=-1&amp;#bottom" style="color:silver" title="Jump to last post"><img src="/img/forum/arrow.gif" width="16" height="17" alt="Jump to last post" border="0"></a>
			</td>
		</tr> 

I want to write a code (using getElement???) to display "iPhone 4 back scratch?" and i"Phone 5 - let the rumours begin (Part 2)". Looking around for ages but not sure.. I am able to use getElementById to get the whole text of the whole day div but I just want to extract that information only...
