Hello, Mi,

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

Notepad++:

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()
{
InitializeComponent();

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);
this.radSyntaxEditor1.TaggersRegistry.RegisterTagger(xmlTagger);
this.radSyntaxEditor1.TaggersRegistry.RegisterTagger(xmlFoldingTagger);

}

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.
