title: How to select column in a table
body: <p>I get tables, without any css attributes, some columns are optional. </p>
  
  <pre><code>&lt;TABLE&gt;
  &lt;TR&gt;
      &lt;TH&gt;name A(optional)&lt;/TH&gt;
      &lt;TH&gt;name B&lt;/TH&gt;
      &lt;TH&gt;name C&lt;/TH&gt;
  &lt;/TR&gt;
  &lt;TR&gt;
      &lt;TD&gt;name 1A(optional)&lt;/TD&gt;
      &lt;TD&gt;name 1B&lt;/TD&gt;
      &lt;TD&gt;name 1C&lt;/TD&gt;
  &lt;/TR&gt;
  &lt;TR&gt;
      &lt;TD&gt;name 2A(optional)&lt;/TD&gt;
      &lt;TD&gt;name 2B&lt;/TD&gt;
      &lt;TD&gt;name 2C&lt;/TD&gt;
  &lt;/TR&gt;
  &lt;/TABLE&gt;
  </code></pre>
  
  <p>I need to select column with name "name B", but this collumn is not always second!
  So I need to select it according to name. </p>
  
  <p>In the worst-case scenario according to id attribute in header </p>
  
  <pre><code>&lt;TH id="nameB"&gt;name B&lt;/TH&gt;
  </code></pre>
