Question

how can i select the second Tag?

$("head > style:nth-child(2)").html();

Answer 1

If your html looks like this for example:

​<div id="container">
  <span id="span1"></span>
  <span id="span2"></span>
</div>​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

Your script:

var secondChild = $('div#container > *:eq(1)');

​
Where on eq(n): n is the zero-based index of the child you want to get. In this case, 1 points to the second child of <div>.
