How to parse html text into plain text without attributed string?

Question

How do I parse html text into plain text without attributed string?

This is my code:

(NSString *)convertHTML:(NSString *)html {
    NSScanner *myScanner;
    NSString *text = nil;
    myScanner = [NSScanner scannerWithString:html];
    while ([myScanner isAtEnd] == NO) {
        [myScanner scanUpToString:@"<" intoString:NULL];
        [myScanner scanUpToString:@">" intoString:&text];
        html = [html stringByReplacingOccurrencesOfString:[NSString stringWithFormat:@"%@>", text] withString:@""];
    }
    //
    html = [html stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
    return html;
}

Assuming you have access to a UIWEbView of some kind, you could execute some javascript to retrieve the .text() of an element which contains the HTML you want to stringify?

You can use the below code and get from here

-(NSString *)stringByStrippingHTML:(NSString*)str
{
    NSRange r;
    while ((r = [str rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location     != NSNotFound)
    {
        str = [str stringByReplacingCharactersInRange:r withString:@""];
    }
    return str;
}

NSString *hstmString = @"This is <font color='red'>simple</font>";

NSString* strWithoutFormatting = [self stringByStrippingHTML:hstmString];

NSLog(@"%@", strWithoutFormatting);

It maybe help you :)

If using a library is an option you could try HTMLKit.

For example, given the following HTML:

Some text to extract

one way to parse it to plain text would be:

// create a <div> element
HTMLElement *element = [[HTMLElement alloc] initWithTagName:@"div"];
// set its innerHTML
element.innerHTML = @"<p>Some <b>text</b> to <em>extract</em></p>";
// textContext of the element contains all the text
NSLog(@"%@", element.textContent);
// You get: 'Some text to extract'

Let me know if you need further help.

If your HTML is simple and parsing it is not the core functionality of your app/project, then maybe HTMLKit is not for you, since it is a full-fledged HTML parser.
