The iphone app im writing displays an html page, i would like to add a search feature where the user can search for instances for the keyword and highlight them (like in firefox using ctrl+F)

what's the best way to do this? in objective-c? would this be even possible with javascript?

Please point me to the right direction

 

NSString *filePath = PATH_OF_HTML_FILE; NSError *err = nil; NSString *pageHTML = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&err]; if(err) {
       pageHTML = [NSString stringWithContentsOfFile:filePath encoding:NSASCIIStringEncoding error:&err]; } if([searchTxtField.text length]) {
       NSRange range1 = [pageHTML rangeOfString:searchTxtField.text options:NSCaseInsensitiveSearch]; if(range1.location != NSNotFound)     {
           NSString *highlightedString = [pageHTML substringWithRange:range1];         pageHTML = [pageHTML stringByReplacingOccurrencesOfString:highlightedString withString:[NSString stringWithFormat:@"%@",highlightedString] options:NSCaseInsensitiveSearch range:NSMakeRange(0, [pageHTML length]) ];         [webView loadHTMLString:pageHTML baseURL:[NSURL fileURLWithPath:filePath]];     } }
