Dear All,
I am trying to convert AuthorNode at caret position to String so it could be, after some tweaking, pasted instead of that original element. But I have difficulties iterating the element children in case of mixed content as 'getContentNodes()' method returns just elements, not text nodes.

Code: Select all

    private static String getXmlFragment(AuthorNode authorNode) throws BadLocationException {

        StringBuilder xmlFragment = new StringBuilder();
        switch (authorNode.getType()) {
            case AuthorNode.NODE_TYPE_TEXT : {
                xmlFragment.append(authorNode.getTextContent());
                break;
            }
            case AuthorNode.NODE_TYPE_ELEMENT: {
                d docbookElement = (d) authorNode;
                xmlFragment.append("<" + docbookElement.getName());
                for (int i = 0; i < docbookElement.getAttributesCount(); i++) {
                    String attr = docbookElement.getAttributeAtIndex(i);
                    if (!attr.startsWith("xmlns")) {
                        xmlFragment.append(" " + attr + "=\"" + docbookElement.getAttribute(attr).getValue() + "\"");
                    }
                }
                xmlFragment.append(">");

                for (AuthorNode contentNode : docbookElement.getContentNodes()) {
                    xmlFragment.append(getXmlFragment(contentNode));
                }
            /*
                ContentIterator ci = docbookElement.getContentIterator();
                while (ci.hasNext()) {
                    xmlFragment.append(ci.next());
                }
            */
                xmlFragment.append("</" + authorNode.getName() + ">");
            }
        }

        return xmlFragment.toString();
    }

Any idea how to convert the content properly?
Thanks, Jan

Hi Jan,

We have specific API for what you need:
https://www.oxygenxml.com/InstData/Edit ... tFragment-

Coming back to your remarks, the Author Nodes structure looks like the one in the image here:
https://www.oxygenxml.com/InstData/Edit ... gment.html
Indeed there are only element nodes, no text nodes. Each node points using the "getStartOffset()" and "getEndOffset()" methods to a large content string containing all text characters and special characters for the node start/end offsets. And there are methods like "AuthorDocumentController.getChars(int, int, Segment)" which allow you to access text between two offsets.

Regards,
Radu

Cool, I was not aware of that method. In my case I use AuthorNode as an Input:

Code: Select all

AuthorDocumentFragment uLinkFragment = documentController.createDocumentFragment(uLinkElement, true);
String uLinkXmlFragment = documentController.serializeFragmentToXML(uLinkFragment);
// modifying the fragment 
documentController.deleteNode(uLinkElement);
documentController.insertXMLFragment(uLinkXmlFragment, authorAccess.getEditorAccess().getCaretOffset());

It works, but while the original fragment contains attributes in the desired order, the insertXMLFragment method is causing reordering them alphabetically...

That alphabetical sorting is only in the Author mode, not in the XML source. It is caused by the settings, which can be disabled in Preferences...|Editor|Edit Modes|Author: Sort attributes alphabetically for "Full Tags with Attributes".
