DicomXmlNodeType Enumeration

Summary
Identifies the type of XML node that is about to be written to the XML output file. These values are used in the SaveXmlData object. For an example, refer to SaveXmlCallback.
Syntax
C#
C++/CLI

0None The XML node is an unknown type.
1Element The XML node is an XML element.
2Comment The XML node is an XML comment.
