Need help breaking up string

[rdrews]

Posted this here http://www.phpfreaks.com/forums/index.php/topic,280070.0.html but don't seem to be getting a lot of assistance (cags actually provided great help but I'm still lost) so I figure maybe regex isn't the right way to go (also suggested by cags).  Here is my problem...

 

Ok, here is a sample of the string I need broken up...

*********End Sample**************

 

 

Ok...all of this is HTML source from Google Docs that I saved into a large .txt file.  Basically, I need all of this broken into two parts.  Account numbers and comments.

 

All the account numbers are found right after the name which is AFTER the <div class="PubSectionHeader"><font size="+0"> and BEFORE the </font>

 

And all the comments look to be between <div class="PubNoteContentArea"> and </div> but there are usually several separate notes for each account number.  So a single account number may have several <div class="PubNoteContentArea"> note areas.

 

Ideally I would like to run through this whole text file and end up with two arrays.  One array would be all account numbers (accountNum[0] = "123", accountNum[1] = "456", etc...) and the other array would be all the notes (notes[0] = "notes for account 123", notes[1] = "notes for account 456", etc...) but if it's easier/makes more sense to do one array where the first element would be the account number, the second the notes for the account in the first element, the third, another account number, etc.... then I can work with that too.

 

I realize there is some additional formatting in between some of the <div class="PubNoteContentArea"> note areas like "<blockquote class="gn_c">" and maybe some other stuff but for now I'm not really worried about all that.  I can maybe put the whole file into word or excel and do a few find/replaces to get rid of some of that.

 

Up to this point I have loaded the whole file contents into a string and then split the string into a character array where every character (including whitespaces) is an element in the array.  I then tried to start messing with the regex part of it and decided I wasn't getting anywhere after a while of playing around with it.  Any help is greatly appreciated.  If I didn't explain things very well feel free to ask me to clarify.

 

UPDATE*

With Cags provided code I get $matches[2] which holds all the account numbers for me but I can't figure out how to get all the notes associated with all those account numbers.  It won't be as straight forward as getting the account numbers (I think) because there may be several notes per account number.  If I am going about this the wrong way (with regex) suggestions are more than welcome. 

 

Thanks!
