I've done exactly that but using an XML schema. I wrote the code myself -
it's quite straightforward. In essence my Document contains both the actual
XML document AND another instance of the JDom Document which is the
My Document then provides methods to:
1) check if one element can be a child of another
2) return a list of all possible children of the given element.
Note in each case I check based on the element (not element type) so that I
can take into account restrictions on multiplicity.
Hope this points you in the right direction.

Subject: [jdom-interest] DTD parsing/validation question
Has anybody written code based on JDOM and the DTD parser
from Mark Wutka to determine what are :
1) valid predecessors of a given JDOM node (to insert before the given node)
2) valid successors of a given JDOM node (to insert after the given node)
3) valid children of a given JDOM node (to add as a child to the given node)
The idea is to populate a popupmenu on a tree node with
only those tags that are valid given the DTD and the current
state of the document.
Any ideas or better yet, code, would be very much appreciated.
