Q:

Find the same divs in DOM tree

I have a DOM tree:
<div id="all">
  <div id="second">
    <div id="target"></div> *
    <div id="somediv"></div>
  </div>
  <div id="second">
    <div id="target"></div>
    <div id="somediv"></div>
  </div>
  <div id="second">
    <div id="target"></div>
    <div id="somediv"></div>
  </div>
</div>

How I can get all divs with id="target"? 
$('#second').siblings().andSelf().children(':first')  - shows only the first target (*), ignoring the rest.

A:

You can't have multiple divs with the same ID in an HTML document. Instead, use class="target". Then you can get all divs with the class target in all with
$("#all .target")
