RadSyntaxEditor: Character data sections are not recognized by XmlTagger

If my xml string contains an element with attributes, XMLFoldingTagger just ignores it!


For example:

<Formular DebugMode="F" Version="1" Typ="Rechnung">




is ignored. Element Formular is not recognized by the XMLFoldingTagger. Only simple elements are recognized, like:

Hello, Mi,    

The provided code snippet is greatly appreciated. I was able to observe the described behavior:


I confirm that this is an issue with the current parsing logic in the XmlFoldingTagger. I have approved this bug report.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to add a closing tag ("</") for the CDATA:

Thus, the FirstElement will be foldable.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

I made a small example which shows the real problem. The Problem is XMLFoldingTagger has problems with CDATA:


        public RadForm1()

            XmlDocument xml = new XmlDocument();
            xml.PreserveWhitespace = true;
            xml.LoadXml("<FirstElement>\r\n  <OtherElements>\r\n    <![CDATA[]]>\r\n  </OtherElements>\r\n</FirstElement>");

            this.radSyntaxEditor1.Document = new TextDocument(xml.OuterXml);

            XmlTagger xmlTagger = new XmlTagger(this.radSyntaxEditor1.SyntaxEditorElement);
            XmlFoldingTagger xmlFoldingTagger = new XmlFoldingTagger(this.radSyntaxEditor1.SyntaxEditorElement);


If you run this sample, FirstElement is not foldable. If you remove the CDATA-entry it is.

Sorry for posting too fast, the title should be changed to:

XMLFoldingTagger doesn't recognizes elements with attributs, when a CDATA is used in a child element

In my example OtherElements should be replaced with


I think CDATA is the thing which breaks XMLFoldingTagger.
