Linq To XML's core class XElement, one XElement represents a node, new XElement("Order"), creates a named Order Label, call Add to add child nodes, which is also an XElement object!
The following are several common forms of LINQ operating XML.
///Write file (generate node properties)
XElement ePersons = new XElement("Persons"); XElement ptom = new XElement("Person"); //增加一个Person节点 ptom.Add(new XElement("Name", "Tom"));//在ptom下再增加子节点 ptom.Add(new XElement("Age", "18")); ePersons.Add(ptom);
XElement pjack = new XElement("Person"); pjack.Add(new XElement("Name", "Jack")); pjack.Add(new XElement("Age", "20")); ePersons.Add(pjack);
Final generation:
Tom 18 Jack 20
///Write file (generate attributesNature)
XElement ptom = new XElement("Person"); ptom.Add(new XAttribute("Name", "tom"));//添加XAttribute就生成属性 ptom.Add(new XAttribute("Age", "18")); ePersons.Add(ptom); XElement pjack = new XElement("Person"); pjack.Add(new XAttribute("Name", "jack")); pjack.Add(new XAttribute("Age", "20")); ePersons.Add(pjack);
Final generation:
<span style="color: #0000ff;"><span style="color: #800000;">Persons</span><span style="color: #0000ff;">></span><br><span style="color: #0000ff;"><span style="color: #800000;">Person </span><span style="color: #ff0000;">Name</span><span style="color: #0000ff;">="tom"</span><span style="color: #ff0000;"> Age</span><span style="color: #0000ff;">="18"</span><span style="color: #0000ff;">/></span><br><span style="color: #0000ff;"><span style="color: #800000;">Person </span><span style="color: #ff0000;">Name</span><span style="color: #0000ff;">="jack"</span><span style="color: #ff0000;"> Age</span><span style="color: #0000ff;">="20"</span><span style="color: #0000ff;">/></span><br><span style="color: #0000ff;"></span><span style="color: #800000;">Persons</span><span style="color: #0000ff;">></span></span></span></span>
//Read XML and read the value of node format
XDocument xd= XDocument.Load("XML文件地址"); foreach (XElement item in xd.Root.Descendants("Person"))//得到每一个Person节点,得到这个节点再取他的Name的这个节点的值 { Console.WriteLine(item.Element("Age").Value);//Person的节点的下得节点为Name的 } 注释:doc.root(得到根节点的XElement对象).XElement(“tagname”)方法得到的就是节点下第一个名字为tagname的节点。 如果doc.root。XElements(复数形式)就是得到所有的子节点,Descendants("“tagname”")子孙节点
//Read XML and read the value of attribute format
XDocument xd= XDocument.Load(@"D:\Program Files\Demo\Demo\ConsoleApplication2\XMLFile2.xml"); foreach (XElement item in xd.Root.Descendants("Person"))//得到每一个Person节点,得到这个节点再取他的Name的这个节点的值 { Console.WriteLine(item.Attribute("Age").Value);//Person的节点的下得节点为Name的 }

The implementation of RSS in XML is to organize content through a structured XML format. 1) RSS uses XML as the data exchange format, including elements such as channel information and project list. 2) When generating RSS files, content must be organized according to specifications and published to the server for subscription. 3) RSS files can be subscribed through a reader or plug-in to automatically update the content.

Advanced features of RSS include content namespaces, extension modules, and conditional subscriptions. 1) Content namespace extends RSS functionality, 2) Extended modules such as DublinCore or iTunes to add metadata, 3) Conditional subscription filters entries based on specific conditions. These functions are implemented by adding XML elements and attributes to improve information acquisition efficiency.

RSS and XML are tools for web content management. RSS is used to publish and subscribe to content, and XML is used to store and transfer data. They work with content publishing, subscriptions, and update push. Examples of usage include RSS publishing blog posts and XML storing book information.

RSS documents are XML-based structured files used to publish and subscribe to frequently updated content. Its main functions include: 1) automated content updates, 2) content aggregation, and 3) improving browsing efficiency. Through RSSfeed, users can subscribe and get the latest information from different sources in a timely manner.

The XML structure of RSS includes: 1. XML declaration and RSS version, 2. Channel (Channel), 3. Item. These parts form the basis of RSS files, allowing users to obtain and process content information by parsing XML data.

RSS documents work by publishing content updates through XML files, and users subscribe and receive notifications through RSS readers. 1. Content publisher creates and updates RSS documents. 2. The RSS reader regularly accesses and parses XML files. 3. Users browse and read updated content. Example of usage: Subscribe to TechCrunch's RSS feed, just copy the link to the RSS reader.
