XML Parser in Cobol

[WolfgangIreland]

Hello together,
I have to write a program to browse a XML Message and to verify the message. Anyone done the same and give me some hints?
Thanks

Hi,

I saw some examples in the book COBOL UNLEASHED.

WolfgangIreland,

i submitted a similar question under "parsing strings",
thread209-38500 the mean time, i have been dabbling with a solution to the very same problem, except i don't need to verify the document.
Without getting to lengthy, i can give you a couple of hints:

- process the document as a large string; maintain a pointer to the character position from where you are processing at any certain time;
- use reference modification to extract bits from it (thank you, Crox !);
- find tags for example by searching for a &quot;<&quot; and work out which one it is, or check if it is the one you're searching for (whatever you need);
- get the value between the tags by UNSTRINGing it, DELIMITED BY the end tag.

After processing an begin tag / end tag couple, remember to set your pointer ahead of the end tag before searching for a next one; do this either by working out the offset you need, or search for it and set the pointer up by its length (= begin tag length + 1, usually).

Any more questions are welcome, as ever.

Good luck !
