Overarching Question:how do I access entire text of an RTF file

Ok, so I have a bit of a problem here, I'm hoping what I want isn't totally crazy, but here it goes.

I work with cars, and at the end of every day we compile an RTF of the vehicles we found with damages and send them off to someone. We must also keep an Excel file with these VIN numbers and the corresponding damages. I've done some work on the VIN Log part, using VBA to format certain values in certain ways. The RTF file is akin to the below formatting (these are not real VIN, but match the regex for them)

1FTEX8EEG12356789 //Other random Information I do not need
    004121 2
    012051 3
    005091
1FTFW7D78KF123567 //Other Random Information I do not need
    042071
    010341 4
    010341 9
//ETC

Here's my question: I've figured out how to open the RTF file, but how do I gain access to the entirety of the document text all at once, not just paragraph by paragraph, and does the RegExp object have available a way to capture the offset the string was found at?

The reason I am trying to use RegEx is because there's this header, which takes up roughly 10 "Paragraphs" worth of space every page (these documents can be 1 page or sometimes 10 or more). If anyone could point me into a quicker way to accomplish this, I would appreciate it.

What I was thinking I would end up having to do, once I figure out how to RegEx search the whole document was this

1. Gather all RegExp matches for ([A-Z0-9]{17})
2. Use the matches from Step 1 to find out the location in the document via InStr
3. Use the value from Step 2 to loop through each set of matches from step 1, and indexes from step 2 in order to form something akin to the below code.

Code:

For i=1 To RegMatches.Count 
  start_pos = InStr(WordDocumentText,RegMatches.Item(i))
  For j=start_pos To InStr(WordDocumentText,RegMatches.Item(i+1))
    //Code to gather damages on VIN 'i'
  Next
Next

But these seems... redundant and just a sort of messy way to do so.

All I would really need to know are how to get access to the entirety of the text in the RTF file I am opening with VBA, and I can kind of go from there, but if anyone has an better idea on how to go from here with this, I'd appreciate it.
