    </hello2>
</div>
<div id="body">
    <hello>

Answer 1

You can use parenthesis to create groups of nested elements:

(#header>hello2>world2)+(#body>hello>world)

Actually, in this example, the second set of parenthesis isn’t necessary, because the first set creates the first group, which is enough:

(#header>hello2>world2)+#body>hello>world
