You're totally right!
I need to know how many times each word in the first column of the list occour in my text file. Let's say I have this two couple:
 [Aa]tom[oi]:[Nn]ucle[oi]
[Nn]ucle[oi]:[Pp]roton[ei]

[download]
and this text here:
 In particolare, l ' atomo √® composto da un nucleo carico positivamente e da un certo numero di elettroni, carichi negativamente, che gli vibrano attorno senza un ' orbita precisa (l ' elettrone si dice infatti delocalizzato), nei cosiddetti gusci elettronici. Il nucleo √® composto da protoni, che sono particelle cariche positivamente e da neutroni che sono particelle prive di carica: protoni e neutroni sono detti nucleoni. In proporzione se si considera il nucleo grande come una mela, gli elettroni gli ruotano attorno ad una distanza pari a circa un chilometro; viceversa un nucleone ha massa quasi 1800 volte superiore a quella di un elettrone. I'd like it to count how many times Aatomoi occours in this and how many times does Nnucleoi.
The [] stuff is beacuse I have another script that search for this words in a text and I need for it to retrieve all the possible words made with this char: Nucleo, nucleo, Nuclei, nuclei.
I hope I was more clear
