title: How can I extract td from html in bash?
body: <p>I am querying London postcode data from geonames:</p>
  
  <p><a href="http://www.geonames.org/postalcode-search.html?q=london&amp;country=GB" rel="nofollow">http://www.geonames.org/postalcode-search.html?q=london&amp;country=GB</a></p>
  
  <p>I want to turn the output into a list of just the postcode identifiers (Bethnal Green, Islington, etc.). What is the best way to extract just the names in bash?</p>
