Replace you Function with following and pass your HTML string snippet that you have posted.

"<li>Coffee</li>"
"<li>Tea</li>"
"<li>Milk</li>"
"</ol>";

[self stringByStrippingHTML:str];

Function to replace string and Generate Desire output

- (NSString *)stringByStrippingHTML:(NSString *)inputString
{
    NSMutableString *outString;

    if (inputString)
    {
        outString = [[NSMutableString alloc] initWithString:inputString];

        if ([inputString length] > 0)
        {
            NSRange r;
            int index = 1;
            while ((r = [outString rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
            {
                if([[outString substringWithRange:r] isEqualToString:@"<li>"])
                {
                    outString = [[outString stringByReplacingCharactersInRange:r withString:[NSString stringWithFormat:@"\n %d. ",index++]] mutableCopy];
                }
                else
                    [outString deleteCharactersInRange:r];
