--> First, you need to register an OpenedDocumentHook with XXE. See http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xmleditapp/kit/OpenedDocumentHook.html See http://www.xmlmind.com/xmleditor/_distrib/doc/gui/openedDocumentHook.html In order to do this edit attached customize.xxe_gui file, then copy it anywhere inside one of the two addon/ directories of XXE. * Then, your custom OpenedDocumentHook must detect that it is a DocBook file which is being created or opened. Use OpenedDocument.getConfiguration().getName() to detect this. See http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xmleditapp/kit/OpenedDocumentHook.html#documentCreated(com.xmlmind.xmleditapp.kit.OpenedDocument,%20com.xmlmind.xmleditapp.kit.HookStatus) See http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xmleditapp/kit/OpenedDocumentHook.html#documentOpened(com.xmlmind.xmleditapp.kit.OpenedDocument,%20com.xmlmind.xmleditapp.kit.HookStatus) See http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xmleditapp/kit/OpenedDocument.html#getConfiguration() See http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xmleditapp/config/Configuration.html#getName() * Finally, add your custom DocumentListener to the underlying Document of the OpenedDocument. See http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xmleditapp/kit/OpenedDocument.html#getDocument() See http://www.xmlmind.com/xmleditor/_distrib/doc/api/com/xmlmind/xml/doc/Document.html#addDocumentListener(com.xmlmind.xml.doc.DocumentListener,%20boolean) --> DocumentListeners are not intended to contain code which modifies the document. They are meant to let some code *observe* the modifications (e.g. MarkManager, UndoManager, etc). If you want to modify the document, please do not do it directly from within the code of your custom DocumentListener. Instead, do it using SwingUtilities.invokeLater (possibly after merging multiple edits such as those between beginEdit/endEdit or consecutive character insertions or deletions). --> Please note that we cannot help you more than we already did in this email. What you want to do is quite complex. Helping you more would force us to first do a similar development, which is out of question. If what you'll do causes XXE to become very slow or does not work reliably or does not work at all (which I hope will not be the case), please double-check, then triple-check what you did, before submitting further support requests. -------------- next part -------------- A non-text attachment was scrubbed...
