to goes to the point and thru includes the point

No
So to newline does not include the newline?

no it wouldn't

rule: [ digit copy text to newline skip ]
parse stuff [ some rule ]
digits: [ some digit ]
rule: [ digits ... ]

Graham, the digit String would be included in the copied text with 
this?
Graham

[2596x3]
nope
because it matches digit and the cursor moves on
past the digit
amacleod

Right. Anyway to capture the digit?

you can always do something like set n number!

He's using string parsing .. not block parsing

yeah can't use set then.

I'll try that Graham. Thanks

or
non-digits: complement digit
parse [ copy digit-text to non-digits copy text to newline skip ]
and correct syntax helps :)

>> str: "193920347REBOL ROCKS!^/"
== "193920347REBOL ROCKS!^/"

>> parse str  compose [some (charset "0123456789") text: copy text 
thru newline]
== true
>> text
== "REBOL ROCKS!^/"
Something like that?

No

I have a text document with section numbers in front:

2. Hello
2.1 Hello Again
2.1.1 Hello already
3. Goodbye

I want the section number inclued in hte copy
It need not be included in hte same copy just as long as I can record 
it.

So you just want each line then really?

Well it gets a little more complicated.
some parts of the docment will be multilined.
I thought it would be a simple thing that I was missing. I may need 
to re-think the formatting of the document.
[unknown: 5]

[2616x2]
So even if something is multiline you would still want each line 
of the multiline correct?
Or do you mean a multiline might looks something like this:

2.1 Hello
       Goodbye

Where the second line doesn't have the preceeding number?
amacleod
30-Jun-2008
[2618]
Yes and formating may need to be retained
[unknown: 5]
30-Jun-2008
[2619]
Ahhh yes that gets a bit more complicated.

Paul, while you are there...
I was considering using Tretbase for this project

Excellent choise ;-)

Let me briefly explain where I'm going to see if you think its workable 
or perhaps a there is a better solution

I trying to put a set of Fire department related materials online.
THey are now in pdf
I'm converting them to text and reformatting them to parse
I want to hold each section in a seperate database record
So I can index for keywords and search and read only thse sections 
I need.
Photos and diagrams will also be stored.

Well, TRETBASE 1.0 is the only finished product right now.  So the 
only available TRETBASE app is 1.0 which is really not a multi-user 
solution.
It might work for you if you not in need of multi-user (simultaenous 
access)
The next version of TRETBASE which is in work is multi-user and supports 
indexing.
But not finished.

I'm using mysql for the online component but I need a local storage 
method too for offline use

It might work for that.  Can also do the images conversion for you 
in REBOL format which is nice.

That was one of the things that had me thinking of using it.
What I would need is a simple method to sync them

Best thing to do is try it out as it really takes very little time 
to setup and try and you will know probably if it is suitable for 
you in about 10 minutes.

Is there a difference between a "space" and a "tab"? Can you parse 
for tab and not sapce?
