QT's XML parsers (DOM and SAX) can not validate that the XML file conforms to the possible DTD given in the file. I can live with that.
However, I would like to use the DTD information myself, and I have not found a way to do it with QT. I have used DOM parsing, and QDomImplementation has a function "createDocumentType" but no examples are given, and I have not been able to find the right way to use it myself.
It breaks my heart to hard-code the DTD into my program (to assume while writing the code that for example element "paragraph" is always a child of element "myDocument" etc.). I would like to do this in a generic way -
- read in the XML file including the DTD, no need to validate the XML file
- display the XML file elements as a tree (not the DTD info)
- edit the tree and verify at least some of the edit actions by using the DTD information (like copy-paste of the subtrees etc)
- save the tree
surely this cannot require a full-validating XML parser if I make my possible trees simple enough? But how should it be done? Has anyone got an example?
