title: How to loop and extract data from various url's using the iMacros Addon for Firefox
body: <p>I would like to extract data form a spacific url such as www.example.com/data.php?id=xx</p>
  
  <p>Where xx is a number between 1 and 1000 (ie. the script should loop through) and extract the data so far I have the following script:</p>
  
  <pre><code>VERSION BUILD=7401110 RECORDER=FX TAB 
  T=1 
  SET !LOOP 1 
  URL GOTO=http://www.example/data.php?id={{!LOOP}} 
  TAG POS=2 TYPE=TD ATTR=TXT:* EXTRACT=TXT
  </code></pre>
  
  <p>Now how can I achieve this to loop properly also if a url eg www.example.com/data.php?id=4
  does not exist no data is extracted but the script continues and finally how can I get the data to be outputted to a file?</p>
  
  <p>Thanks</p>
