html AgilityPack XPath C# .net 4

Question

I have to define xpath to access second span text to parse the following name-value html structure (see below) loaded to AgilityPack document. I would to do the folowing query using xpath and C#:

var valueSpan = doc.SelectNodes("//div[@class='container']/div[@class='value2' and ???]/span[2]");

Question: I can't write xpath selector for "second matched div with class=="value2". Is it possible to select second "value2" div using xpath or it should be done by indexing childs of "container" node (actual sibling index of "value2" may vary)?

<div class="container">
  <div class="value1">
    <span class="name">Title 1</span>
    <span class="value">some value</span>
  </div>
  <div class="value2">
    <span class="name">Title 2.1</span>
    <span class="value">some value</span>
  </div>
  <div class="value2">
    <span class="name">Title 2.2</span>
    <span class="value">some value</span>
  </div>
  <div class="value3">
    <span class="name">Title 3</span>
    <span class="value">some value</span>
  </div>
</div>

Answer 1

Use:

//div[@class='container']/div[@class='value2'][2]
