How to "retrieve" only useful information in a long list

[alex wu]

Hello,

I have problem in "retrieving" wanted information in a
list field.

For example, the list field has the following content:

Runtime Revolution is a great ...................
.................................................
......................................

FIXED WORDINGS HERE

This is paragraph 2..............................
...................................

Paragraph 3 start here...........................
.................................................
................

Paragraph 4 start here...........................
.................................................
................

Paragraph 5 start here...........................
.................................................
................

ANOTHER FIXED WORDINGS HERE

This is the last paragraph ......................
............


Note:
1. The "FIXED WORDINGS HERE" and "ANOTHER FIXED
WORDINGS HERE" always appear in that two positions.

2. The contents of all paragraphs will be different
with different list.

Here's what I want to do:

I only want the content from "FIXED WORDINGS HERE" to
"ANOTHER FIXED WORDINGS HERE". Because this is the
information I only needed.  How can I do that?

P.S.Actually the list are very long, much longer than
the above example.

Thanks and best regards

Alex
