I am querying London postcode data from geonames:

http://www.geonames.org/postalcode-search.html?q=london&country=GB

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?

    I’m not sure if you mean this \n delimited list (or one in brackets and comma delimited) 

    html='http://www.geonames.org/postalcode-search.html?q=london&country=GB'
wget -q "$html" -O - |
  w3m -dump -T 'text/html'|
    sed -nr 's/^ +[0-9]+ +(.*) +[A-Z]+[0-9]+ +United Kingdom.*/\1/p'

    w3m is a: “WWW browsable pager with excellent tables/frames support”

    output (first 10 lines) 

    London Bridge   
Kilburn         
Ealing          
Wandsworth      
Pimlico         
Kensington      
Leyton          
Leytonstone     
Plaistow        
Poplar
