Complicated email parse or text extraction and database insertion

[code_worthy@bellsouth.net]

I am trying to strip some data out of numerous emails and place it in
my database. I know that this seems as if it has been done before.
But, this is a little different. First, the numerous emails all have a
set of data that needs to be extracted and inserted into the database.
Some of the data in the email is id, name, address, city, state, zip,
company, etc. The catch is that the date is formated and presented
differently in each email. Take into consideration the following email
examples:
- excert from email #1
ID:............ .. 12345
Name:.......... .. JOHN DOE
Address:....... .. PO BOX 9999
City:.......... .. Somecity
State:......... .. CA
Zip Code:........ 90210
=============== =============== =============== =============== ===

Company Information:

1.:-
Company Name:....... Perl N PHP Scripts Welcome

- excert from email #2
Full Name -- Doe, John
Address -- PO BOX 9999
City -- Somecity St -- California
Zip -- 90210
Company Name -- Perl N PHP Scripts Welcome
ID -- 12345

- excert from email #3
Name.....Addres s.....City..... State.....Zip.. ...Identificati on
Number.....Comp any
John Doe.....PO Box
9999.....Someci ty.....CA.....9 0210.....12345. ....Perl N PHP Scripts
Welcome

- excert from email #4

Name.........Ad dress.........C ity.........Sta te.....Zip..... ..Identificatio n
Number.....Comp any
JOHN DOE.....PO BOX
9999.....SOMECI TY.....CA...... ..90210.....123 45............. ........Perl
N PHP Scripts Welcome

Can anyone help me with either scripts that have already been
developed or suggestions on how to go about striping out the needed
information from emails with out knowing their format or order of the
data? THANKS IN ADVANCE.
