title: .docx file chapter extraction
body: <p>I would like to extract the content of a <code>.docx</code>file, chaptervise.
  So, my <code>.docx</code>document has a register and every chapter has some content</p>
  
  <pre><code> 1. Intro
     some text about Intro, these things, those things
   2. Special information
     these information are really special
      2.1 General information about the environment
        environment should be also important
      2.2 Further information 
        and so on and so on
  </code></pre>
  
  <p>So finally it would be great to receive a <code>Nx3</code> matrix, containing the index number, the index name and at least the content.</p>
  
  <pre><code>i_number     i_name                 content
  1            Intro                  some text about Intro, these things, those things
  2            Special Information    these information are really special
  ... 
  </code></pre>
  
  <p>Thanks for your help</p>
