I'm need to parse a text control or Rtf control into several lines. I plan populate an OBX segment for transcriptions. I have the code for building the actual HL7 message. Just need some help on the parsing logic.
Thanks
Michael

I am not quite following what you are trying to do. Are you wanting to take the OBX record, break it up into multiple lines then throw it into a text or RTF control? Or do you have a text or RTF control populated with the OBX record and want to extract it out?

Are you just looking to parse a textfield (or RTF stored as text) into component lines?
Dim MyStringArray as String() = MyBO.MyTextfield.Split(New String() {Chr(13)}, StringSplitOptions.RemoveEmptyEntries)

Thanks guys,
I have a text or RTF. I want to extract the text and populate multiple OBX segments with each line (including blank spaces). I have been extracting except that I get bit of a formatting mess like most of the paragrah in one OBX.
not pretty.

Well, I have lived in the realm of EDI interfaces for a good long while now and this can be a really deep topic in regards to EDI parsing. However, if you are just trying to get the line breaks, then Charles suggestion should work just fine.

Ok, thank,
Yeah, My message is generating but I need to clean it up.
Thanks Guys!

To be, or not to be, that is the question: whether 'tis nobler in the mind to suffer the slings and arrows of outrageous fortune, or to take arms against a sea of troubles and by opposing end them. To die-to sleep, no more; and by a sleep to say we end the heart-ache and the thousand natural shocks that flesh is heir to: 'tis a consummation devoutly to be wish'd. To die, to sleep; to sleep, perchance to dream-ay, there's the rub: for in that sleep of death what dreams may come, when we have shuffled off this mortal coil, must give us pause-there's the respect that makes calamity of so long life. For who would bear the whips and scorns of time, th'oppressor's wrong, the proud man's contumely, the pangs of dispriz'd love, the law's delay, the insolence of office, and the spurns that patient merit of th'unworthy takes, when he himself might his quietus make with a bare bodkin? Who would fardels bear, to grunt and sweat under a weary life, but that the dread of something after death, the undiscovere'd country, from whose bourn no traveller returns, puzzles the will, and makes us rather bear those ills we have than fly to others that we know not of? Thus conscience does make cowards of us all, and thus the native hue of resolution is sicklied o'er with the pale cast of thought, and enterprises of great pitch and moment with this regard their currents turn awry and lose the name of action. |

Be aware the .Split() thing has a lot of flexibility.
Should your example yield 7 lines or is there a fixed length to the line and you want to slice it into even pieces?
|
By Michael Reese - 3/8/2010
I need to see the lines and and breaks and spaces between lines. Do you have a code example?
Thanks

By Charles R Hankey - 3/9/2010
Not sure what you mean by "the lines and breaks and spaces between the lines."
The same you posted is hard to decipher because it wraps and we don't know where the lines break. What is the breaking char? Chr(10) chr(13) or a combination? Are there blank lines? What determines where a line begins and ends?
If you can give some very specific answers about the structure parsing it will be pretty easy.
( see my previous question - in the example you posted, how many lines would that break into? )

By Charles R Hankey - 3/9/2010
Stretching out your sample on my big monitor it seems to be just a delimited file using a pipe seperator. What happens if you try the example of the split() I showed you? If that doesn't work try it with a combination of Chr(13) and chr(10)
You should end up with a string array with one line per item.
Hard to tell how it is structured from the sample but there should be some rules as to where lines break.

Ok,
I need to read the textbox. Parse the contents into several lines each in the obx segment above. I will like to have it read the text object and set the line or row length and include carriage returns.
Thanks
Michael

I must not be asking my questions properly because you aren't answering them and just keep saying the same things over and over again so I will bow out and let someone else take a shot at it.
Good luck.

Michael,
Part of my confusion is why you are working on EDI out of a text box. I really don't know what part you are not getting either based on the comments on this thread so far.
So let me tell you what I generally do when working with EDI. In a very simple sample, the Split is an awesome feature and I will use it. However, when parsing EDI, it is generally best to create a reader. If you are reading out of a file, then I would create a FileStream then a StreamReader off of that file stream. You can also use a StringReader which would look something like this:
string line;
string[] segments;
System.IO.StringReader reader = new System.IO.StringReader(MyTextBox.Text);
line = reader.ReadLine();
while(!string.IsNullOrEmpty(line))
{
//-- Parse the line here. You may want to use a split at this point for segment delimitters (i.e. a pipe [|])
segments = line.Split(new char[] { '|' }, StringSplitOptions.None);
//-- Determine the segment type
switch(segments[0])
{
case "OBX":
{
//-- Place your OBX logic here
} break;
}
//-- Read the next line
line = reader.ReadLine();
}
