body: <p>I need to gather a list of components from a file. The components are always in the same format which is '(Space)(Space)(Component)(Space)' </p>
  
  <p>Here is how the file is formatted;</p>
  
  <pre><code>  C500          1u    10    10 f PN"00210856" "CAP 1uF 10% 0805";
    C501          1n    10    10 f PN"00072210" "CAP 1nF 10% 0402";
    C502         22n    10    10 f PN"00196403" "CAP 22nF 10% 0603";
    C503      9.999p    10    10 f PN"C_NF" "NO FIT CAPACITOR";
    C504      9.999p    10    10 f PN"C_NF" "NO FIT CAPACITOR";
    C505      9.999p    10    10 f PN"C_NF" "NO FIT CAPACITOR";
  </code></pre>
