CsQuery to parse a collection of li items

问题

Here's my code:

CQ dom = CQ.Create(htmlString);
var items = dom[".blog-accordion li"];

foreach (var li in items)
{
    var newTournament = false;
    var test = li["header h2"];
}

Inside the foreach loop li turns into a IDomObject variable and I can no longer drill down further into it.

Any suggestions? Here is the example HTML I'm trying to parse:

<ul>
  <li>
    <header>
      <h2>Test</h2>
    </header>
  </li>
  <li>
    <header>
      <h2>Test 2</h2>
    </header>
  </li>
  <li>
    <header>
      <h2>Test 3</h2>
    </header>
  </li>
</ul>

I need to grab the text of each h2 element.

This is done in order to keep CsQuery consistent with jQuery which behaves the same way. You can convert it back to a CQ object by calling the .Cq() method as such

foreach (var li in items)
{
    var newTournament = false;
    var test = li.Cq().Find("header h2");
}

Or if you'd like more jQueryish syntax, the following also works:

foreach (var li in items)
{
    var newTournament = false;
    var test = CQ.Create(li)["header h2"];
}

Your code, could be re-factored to the following if you'd like:

var texts = CQ.Create(htmlString)[".blog-accordion li header h2"]
              .Select(x=>x.Cq().Text());
