regular expression to extract text

[Mark Light]

Hi I have a file read in as a string that looks like below. What I want to
do is pull out the bits of information to eventually put in an html table.
FOr the 1st example the 3 bits are:
1.QEXZUO
2. C26 H31 N1 O3
3. 6.164   15.892   22.551    90.00    90.00    90.00

ANy ideas of the best way to do this - I was trying regular expressions but
not getting very far.

Thanks,

Mark.
