graham, obviously the simplest solution is to read/lines.

read/lines doesn't work on text in memory AFAIK

and just see if the line starts with one of the headers.

what's the content look like ?
Can't you just post an example Graham ?

ok for you?

Assuming SRC: contains the source text, it seems to work too:

header-char: complement charset "^/:"
EOL2: rejoin [newline newline]
parse/all src [
	some [
		some [pos: #" " (change pos #"-") | header-char]
		#":" pos: newline (change/part pos " {" 1)
		[to EOL2 | to end] pos: (change pos "} ") skip skip
	]
]
probe construct to block! src

Yes ... but I'm going to have to study Steeve's

to see why it doesn't work yet

it will not work if you have CRLF insteed of newlines in the source.
Is that the case ?

I just copied it from here.

i mean for your source data, not for my code

that's what I meant .. I just copied the source data from here.

ok, it works for me

i retry

working now.

Actually yours appears to be the better solution because you don't 
specify the headers

and just pick it up from the formmating of the text

yep

well, I'm impressed :)

you should not

sadly I am.

the parser dies when there is something like "2.5mg" in the text 
wiht invalid decimal error.

should not, give the data please

There is no reason, the content is enclosed in a string before being 
loaded.
If it fails, it's because the whole grammar has changed

probaly blank lines are inserted in the content (where they should 
not)

{CC:
This is the presenting complaint.

Ultram Oral Tablet 50 MG qid prn
}

ok i test that

at first sight, i can say there is too many blank lines

Right, i added skiping of useless newline.

parse/all src [
	some [
		any newline
		some [pos: #" " (change pos #"-") | header-char]
		#":" pos: newline (change/part pos " {" 1)
		[to EOL2 | to end] pos: (change pos "} ") skip skip
	]
]

Could you figure it ?

Anticipated fails:

- if blanks lines are inserted in the content (because blank lines 
should only used as delimiters between headers).
- if header's names can't be converted to words.

afaik... my solution works flawlessly.  we could easily extend the 
header info so it recognises headers without naming them explicitely.

In fact i could extend my solution easly to prevent those errors 
and throwing safe errors it the parsing failed.
I takes 5 minutes to do.

But adding such exceptions or other sub-rules is so easy that i don't 
see the interest to prevent those cases.

It's my philosophy when i write parsing rules.

They are so easy to extend, there is no reason to anticape thoses 
cases by guessing what is in the in the mind of the  final user.
Whe have to extend the grammar ? 
Ok, give me 5 minutes.

The thing is that the user can type what they want ... so have to 
be prepared for anything.

All I ask is that they type the headers in correctly.

I'm not a magician, i can't figure all the cases if the given specifications 
are incompletes.

Everybody has a job to do, it's not mine to work on wrong specifications.

If you can't prevent them to insert blank lines in the content, then 
the Maxim's solution should be used isntead.
With a list of authorized headers.

It's free text ... no way can I prevent users from doing this.

So you can't use automatic recognition of unspecified headers. Easy 
to figure.

if headers are not distinguishable from free text, there is no solution

Not if I use Max's method .. but the headers can be obtained from 
the original object specifications.

do so

the header-lbl rule in my example could be changed so it matches 
up to the first colon, but then, there is a flaw in that the text 
can also include something that LOOKS like a header and then you 
can have a stray value in the object...


in the original example data you posted... this would be hard to 
tackle...

Penicillin - allergy:

That was my original way of doing things.

I built the rule from the object and then parsed the data .. but 
my way relied on the headers being in the correct order.
