Hello everybody,
I need to validate an XML document with a DTD file.
The problem is that <lang> tag is empty some times, (but it should
contain ENG,RUS,SPA...)
which causes en error later in the program. How can I catch this with
DTD validation ?
Is there a way to specify a list of posible values for a tag content ?
Or it only can be done for attributes ?
Any suggestions are greatly appreciated.

Is this your own DTD that you have written
or someone else's that you have been given?

No. Not with a DTD. If you need to check element content you can write
an XSLT program that will do this. Or use a Schema.

Correct.
