Tag & Markup
A Markup means <tag>
Root Node
An xml file must have one and only one root node; it could be accessed by the following 2 approaches:
1)
XmlDocument.DocumentElement
2)
XmlDocument.ChildNodes[0]
XmlNode & XmlElement
Node is more general than Element. Anything in an XML document is a node (e.g. attributes, comments, doctype, etc), but only tags are elements.
In .net, XmlElement and XmlAttribute are derived from XmlNode
Adding a new Element
1)
Approach 1: using TextNode
NewElement = XmlDocument.CreateElement(“Tag”);
NewText = XmlDocument.CreateTextNode(“content”);
NewElement.AppendChild(NewText);
ParentNode.AppendChild(NewElement);
2)
Approach 2: using InnerText
NewElement = XmlDocument.CreateElement(“Tag”);
NewElement.InnerText = “content”;
ParentNode.AppendChild(NewElement);
3)
Approach 3: using InnerXml for nested nodes
NewElement = XmlDocument.CreateElement(“Tag”);
NewElement.InnerXml = “"<Title>Other People's Money</Title><Director>Alan Brunstein</Director><Length>114 Minutes</Length>";
ParentNode.AppendChild(NewElement);
Adding a new Attribute
1)
XmlNode.SetAttribute(“attributeName”, “attributeValue”);
2)
Document.CreateAttribute(), Attribute.SetValue, XmlNode.SetAttributeNode();
Attribute.OwnerElement
This property will return the XmlElement which owns this Attribute.
For XmlAttribute.ParentNode, it always returns null;
XmlComment <!--comments-->
It is also derived from XmlNode, and could be added by 2 steps:
XmlDocument.CreateComment(“comments”);
XmlElement.AppendChild(XmlComment);
Its text could be retrieved by InnerText or Value
CDATA <![CDATA[any text]]>
Any text (include xml tags) inside the CDATA section will be considered to be regular text, the parser will not try to parse text inside the section. XmlCDataSection is also derived from XmlNode.
XmlDocument.CreateCDataSection(“some text<aa></bb”);
XmlElement.AppendChild(XmlCDataSection);
Its text could be retrieved by InnerText or Value
XmlNode.InnerText vs XmlNode.Value
InnerText goes through the descendant XmlText node(s) of an XmlNode, and concatenates their value(s) together.
Value just get the text of this node
