How to select an html element based on his text content?

[sebbbastien]

What should be the selector for this kind of html code:

<h2>Firstname</h2>
<p>John</p>
<!--- some random html code, with random h2 tags -->
<h2>Lastname</h2>
<p>Doe</p>

I would like to fill this struct:

type Person struct {
    Firstname string `pagser:"h2[text=Firstname]+p"`
    Lastname  string `pagser:"h2[text=Lastname]+p"`
}

1. You can define a function write your self.
2. Try the code:

Firstname string `pagser:"h2:contains('Firstname')+p"`
