This little code should do what you want:

for l in readfile("/path/to/your_second_file")
exe "silent g/[^[:alnum:]]" . matchstr(l, '\d\+') . "[^[:alnum:]]/delete"
endfor

Put that in a vim script, while in the buffer containing the first
file, source it with:

:source /path/to/the/script

Best,
Paul
