In this example, we create an instance of the XmlDocument class and load the "books.xml" file read more into memory. We then use the SelectNodes method to retrieve all the "book" elements from the XML file.
If your XML file kişi contain large lists (say tens of thousands of elements), you should definitely be using XmlReader.
After you have read an XML document into either an XPathDocument or XmlDocument object, you güç create an XPathNavigator object to select, evaluate, navigate, and in some cases, edit the underlying XML veri.

The following example illustrates using the XmlDocument class constructor with no parameters and the Load method to read an XML document.
This example writes the price of a book to the console. The price node is the last child of a book node.
The XmlNode class plays an important role. However, this class represents a single node of XML that could be the root node of an XML document and could represent the entire file. This class is an abstract base class for many useful classes for inserting, removing, and replacing nodes, navigating through the document. It also contains properties to get a parent or child, name, last child, node type, and more. Three major classes derived from XmlNode are XmlDocument, XmlDataDocument and XmlDocumentFragment.
We use the WriteAttributeString() method to introduce the ‘xsi’ namespace within the element. The rest of the code structure and elements remain consistent with the previous XmlWriter examples.
XML stands for Extensible Markup Language, it is a popular veri exchange format that is widely used in web applications. XML files yaşama be used to store, transport, and exchange data in a structured format.

For data generation, we introduce a People class housing a Get() method to create an array of random people and GetOne() to create one random Person.
Until now, our XML documents were concise, describing only one person. What if we aim to create an XML document from an array of people? Suppose we desire an XML document with elements:
Load succeeds, but you have an incomplete DOM tree because there is no root level element. Before you save the document, you must add a root level element, otherwise Save will throw an exception.
This example creates a book node, adds attributes to that node, and then adds that node to the document.
