This article will explain in detail how to analyze the types and functions of XML nodes. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

When an XML document is read into memory as a node tree, the node type of those nodes is determined when the node is created. The XML document object Model (DOM) has a variety of node types that are determined by the World wide Web Consortium (W3C) and listed in Section 1.1.1 "The DOM Structure Model". The following table lists the node type, the objects assigned to that node type, and a short description of each node type.

XML Node Type known DOM Node Type and object and description

◆ Document

The container for all nodes in the XmlDocument class tree. It is also called the composition document root, and the document root is not always the same as the root element.

◆ DocumentFragment

The XmlDocumentFragment class contains a temporary bag of one or more nodes without any tree structure.

◆ DocumentType

The XmlDocumentType class represents node.

◆ EntityReference

The XmlEntityReference class represents non-extended entity reference text.

◆ Element

The XmlElement class represents the element node.

◆ Attr

The XmlAttribute class is an attribute of the element.

◆ ProcessingInstruction

The XmlProcessinginstruction class is the processing instruction node.

◆ Comment

The XmlComment class comment node.

◆ Text

The XmlText class belongs to the text of an element or attribute.

◆ CDATASection

The XmlCDataSection class represents CDATA.

◆ Entity

The XmlEntity class represents declare.

◆ Notation

The XmlNotation class represents the notation declared in DTD.

Although attributes (attr) are listed as nodes in section 1.2 "Fundamental Interfaces" of W3C DOM level 1, they cannot be considered children of any element node.

The following table shows other node types that are not defined by W3C, but these types can be used as XmlNodeType enumerations in the Microsoft .NET Framework object model. Therefore, there are no matching DOM node type columns for these node types.

XML node type and description

◆ XmlDeclaration

Indicates that the declaration node .

◆ XmlSignificantWhitespace

Represents valid white space (white space in mixed content).

◆ XmlWhitespace

Represents a blank space in the content of an element.

◆ EndElement

Returns when the XmlReader reaches the end of the element.

Example XML: < / item >

◆ EndEntity

Returned when XmlReader reaches the end of entity replacement due to a call to ResolveEntity.

On how to analyze the types and functions of XML nodes is shared here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
