title: Edit content in header of document Python-docx
body: <p>I am trying to find and replace text in <strong>a Textbox in Header</strong> of document. But after searching for awhile, it seems there is no way to access the content in the Header or "float" text boxes via python-docx (I read issue <a href="https://github.com/python-openxml/python-docx/issues/413" rel="nofollow noreferrer">here</a>)</p>
  
  <p>So, it means we have to find and replace directly on the xml format of document. Do you know anyway to do that? </p>
