Ciao a tutti, ho bisogno del vostro aiuto.  
Non riesco a ricavare da una pagina html, tutti i link che mi servono,  
utilizzando questo script

#main è la pagina scaricata in maniera corretta ed è di tipo String  
er=Array.new  
er \<\< main[’

(…)

* * *
’]  
puts “Post search”  
puts “Valore #{er.class}”  
for i in er  
puts i  
end
