Answer 1

I used Ben Reeves' HTML Parser to achieve what I wanted:

NSError *error = nil;
NSString *html = 
    @"
"
        "
"
        "
"
    "
"
    "Hello World 1"
    "Hello World 2";
HTMLParser *parser = [[HTMLParser alloc] initWithString:html error:&error];

if (error) {
    NSLog(@"Error: %@", error);
    return;
}

HTMLNode *bodyNode = [parser body];

NSArray *inputNodes = [bodyNode findChildTags:@"input"];

for (HTMLNode *inputNode in inputNodes) {
    if ([[inputNode getAttributeNamed:@"name"] isEqualToString:@"input2"]) {
        NSLog(@"%@", [inputNode getAttributeNamed:@"value"]); //Answer to first question
    }
}

NSArray *spanNodes = [bodyNode findChildTags:@"span"];

for (HTMLNode *spanNode in spanNodes) {
    if ([[spanNode getAttributeNamed:@"class"] isEqualToString:@"spantext"]) {
        NSLog(@"%@", [spanNode allContents]); //Answer to second question
    }
}

[parser release];
