title: Data scraping with wget and regex
body: <p>i'm just learning bash scripting, i was trying to scrape some data out of a site, mostly wikitionary. This is what I'm trying on the command line right now but it is not returning any result</p>
  
  <pre><code>wget -qO- http://en.wiktionary.org/wiki/robust | egrep '&lt;ol&gt;{[a-zA-Z]*[0-9]*}*&lt;/ol&gt;'
  </code></pre>
  
  <p>What i'm trying is to get the data between the  tags, just want them to be displayed. Can you please help me find out what I'm doing wrong ?</p>
  
  <p>Thanks</p>
