有没有办法将标记作为schema.org itemprop的值？

Question

Is there a way to have markup as the value to a schema.org itemprop node? Eg this works:

<div itemscope itemtype ="http://schema.org/Movie">
  <h1 itemprop="name">Avatar</h1>
  <span>Director: <span itemprop="director">James Cameron</span> (born August 16, 1954)</span>
  <span itemprop="genre">Science fiction</span>
  <a href="../movies/avatar-theatrical-trailer.html" itemprop="trailer">Trailer</a>
</div>

But can you make this work:

<div itemscope itemtype ="http://schema.org/Movie">
  <h1 itemprop="name">Avatar</h1>
  <span>Director: <span itemprop="director">James Cameron</span> (born August 16, 1954)</span>
  <span itemprop="genre"> <p>Science</p> <h2>fiction</h2></span>      <<====
  <a href="../movies/avatar-theatrical-trailer.html" itemprop="trailer">Trailer</a>
</div>

Answer 1

The HTML spec defines what the property value is of an element with an itemscope attribute , and it says for elements other than meta , audio , embed , iframe , img , source , track , video , a , area , link , object , data , meter , or time , “ The value is the element's textContent “.

So the HTML spec requires consumers of microdata markup to ignore markup inside the span element in <span itemprop="genre"> <p>Science</p> <h2>fiction… and just use the text.
