How to highlight a string in xml document?

[kyu]

Hi,
I have an xml document displayed in the oxygen xml editor and know the referenceGuid of the string I need to highlight.

Basically the reverse of what's asked in this thread but high lighting all the words inside the tag when I have the referenceGuid:

Thank you,

Hello,

What I understand is that you have the value of the "referenceGuid" of an attribute and you want to select the text inside the element.
If you are writing code inside a framework or plugin you can use the JS API:

• to locate the XML DOM element that has a specific referenceGuid by doing a traversal of the DOM tree: https://www.oxygenxml.com/maven/com/oxy ... nt__anchor

• to select some content: https://www.oxygenxml.com/maven/com/oxy ... nager.html .

Best,
Cristian

Hi Christian,
I'm using the following code and getting the following error (I am getting elements back in the getElementsByTagName call):

Code: Select all

var editingSupport = editorGlobal.getEditingSupport();
var elements = editingSupport.getDocument().getElementsByTagName("reference");
var selectionManager = editorGlobal.getSelectionManager();
var selection = selectionManager.createAroundNode(elements.item(0));
editorGlobal.getEditingSupport().getPersistentHighlightsManager().addHightlight(null);

Could you please help me find the correct syntax?

Thank you,
Karen

Hello,

Maybe there is no 'reference' element in the document. Use console.log to print the resulting elements, to see if this is the case.

I didn't include the console.log statements in the code snippet. This is the output for document and elements. It looks like it is returning the two reference elements I have.

Hello,

From the "Uncaught TypeError: Cannot read properties of undefined (reading 'getType')" it seems that you call SelectionManager.createAroundNode() with an undefined object as parameter. Please double-check that.
Also notice that the objects printed in the console from the last screenshot are sync.api.dom.Element objects, not HTMLElement objects.

If you consider that's a bug in one of the JavaScript API methods from Oxygen XML Web Author please provide the following:

• the exact method that doesn't respect its documentation or that has a bug
• a script that we can run to reproduce the problem
• the expected behavior
• the actual behavior

This is one of the reference elements in the xml.

<description><reference referenceGuid="ffa25acc-4af5-4e13-9230-8d2255932be3">Two</reference> </description>

And this is the code with the console logs.

Code: Select all

editorGlobal = e.editor;
var editingSupport = editorGlobal.getEditingSupport();
console.log("document: ", editingSupport.getDocument());
var elements = editingSupport.getDocument().getElementsByTagName("reference");
console.log("elements: ", elements);
var selectionManager = editorGlobal.getSelectionManager();
var selection = selectionManager.createAroundNode(elements.item(0));
console.log("selection: ", selection);
editorGlobal.getEditingSupport().getPersistentHighlightsManager().addHightlight(null);

Could you please confirm this is the correct syntax for adding highlights?

Hello,

Here are the changes you must do in your code, to add highlights to the reference elements:
1. Set the selection created around the reference node: after obtaining the selection from the createAroundNode method, you must call the setSelection API.
2. There is a typo in your code (addHightlight must be changed to addHighlight).
Also, make sure you first check if the list of elements is not empty (so that the "Cannot read properties of undefined (reading 'getType')" error wont happen again).

Thank you, that worked in highlighting.
