    I don’t think -stringByEvaluatingJavaScriptFromString: is a good choice here. Try using an NSScanner:

    NSScanner* scanner = [NSScanner scannerWithString:yourHTML];
while ([scanner scanUpToString:@"a href='" intoString:nil])
{
    [scanner scanString:@"a href='" intoString:nil];
    NSString* result = nil;
    [scanner scanUpToString:@"'" intoString:&result];
    //Do something with result, which will equal 001, then 002, etc.
}

    Note that if you need to parse HTML you didn’t write yourself, you’ll need to add a lot more flexibility to this to account for possible stylistic differences (e.g. ' vs ", href vs HREF).
