Hi,

I use WhatAttributesCanGoHereContext class to obtain a list of possible insert after the node elements, but the list is not identical with the items displayed in the tab element (after).

how I can have just the list of elements to be inserted after the node (as in the Elements tab) ?

here is my code :

Code: Select all


WhatElementsCanGoHereContext whatElementsCanGoHereContext = authorSchemaManager

			.createWhatElementsCanGoHereContext(authorPageAccess.getCaretOffset());

if (whatElementsCanGoHereContext != null) {

	List<CIElement> whatElementsCanGoHere = authorSchemaManager

						.whatElementsCanGoHere(whatElementsCanGoHereContext);

if (whatElementsCanGoHere != null) {



  for (CIElement ciElement : whatElementsCanGoHere) {

	if("PAR_ET".equals(ciElement))								

   	   boolean find = true;

}

Best regards,
Hmida.

Hi Hmida,

If you want to know the list of elements which can be inserted after the current element you need to create the context based on a caret offset which is after the element, something like:

Code: Select all

      AuthorNode nodeAtOffset = authorAccess.getDocumentController().getNodeAtOffset(authorPage.getCaretOffset());

      int offsetAfter = nodeAtOffset.getEndOffset() + 1;

      WhatElementsCanGoHereContext contextAfter = authorSchemaManager.createWhatElementsCanGoHereContext(offsetAfter);

Hi Radu,
This code work fine :

Code: Select all


if(position != null && position.equals("BEFOR")){

  whatElementsCanGoHere = authorSchemaManager

     .createWhatElementsCanGoHereContext(authorAccess

                                         .getEditorAccess().getSelectionStart());

}else if(position != null && position.equals("AFTER")){

    whatElementsCanGoHere = authorSchemaManager

      .createWhatElementsCanGoHereContext(authorAccess

                                          .getEditorAccess().getSelectionEnd());

}

					

if (whatElementsCanGoHere != null) {

    List<CIElement> elements = authorSchemaManager.whatElementsCanGoHere(whatElementsCanGoHere);

						

   if (elements != null) {

							

   for (CIElement ciElement : elements) {

     if(elementName != null && elementName.equals(ciElement.toString())){

	canGoHere = true;

   }

}}}

my xml doc :

Code: Select all


<Tag0>

   <a>

   <b> (user select this node)

   <c> 

   <d>

</Tag0>

How can I initialize the context dynamically :
When the user select the node '<b>', I want to know if it can insert an element at the end of the section (between <d> and </ Tag0>).

Regards,
Hmida.

Hi Hmida,

I'm sorry but I do not understand.

You also have the API:

ro.sync.exml.workspace.api.editor.page.author.WSAuthorEditorPageBase.getFullySelectedNode()

to give you the node which is currently fully selected by the user.

Each node has getParent(), getStartOffset() and getEndOffset() methods.
Each parent node has a ro.sync.ecss.extensions.api.node.AuthorParentNode.getContentNodes() method which can be used to iterate child nodes.

The general AuthorNode architecture which is exposed via the API looks like this:

You have a hierarchy of nodes which point to a common sequence containing all the text nodes from the XML document.
