ASP.net The example of creating, querying, and modifying XML files with namespaces _ Practical tips

C#:

String w3namespace = "http://www.w3.org/2000/xmlns/";
System.Xml.XmlDocument doc = new System.Xml.XmlDocument ();

To create a root node
System.Xml.XmlNode root = Doc. CreateNode (System.Xml.XmlNodeType.Element, "w", "Worddocument", "http://schemas.microsoft.com/office/word/2003/2/wordml");
System.Xml.XmlAttribute xa;
Xa = doc. CreateAttribute ("xmlns", "V", w3namespace);
Xa. Value = "URN:SCHEMAS-MICROSOFT-COM:VML";
Root. Attributes.append (XA);

Adding attributes to a node
Xa = doc. CreateAttribute ("xmlns", "W10", w3namespace);
Xa. Value = "Urn:schemas-microsoft-com:office:word";
Root. Attributes.append (XA);

Xa = doc. CreateAttribute ("xmlns", "SL", w3namespace);
Xa. Value = "Http://schemas.microsoft.com/schemaLibrary/2003/2/core";
Root. Attributes.append (XA);

Xa = doc. CreateAttribute ("xmlns", "AML", W3namespace);
Xa. Value = "Http://schemas.microsoft.com/aml/2001/core";
Root. Attributes.append (XA);

Xa = doc. CreateAttribute ("xmlns", "wx", w3namespace);
Xa. Value = "Http://schemas.microsoft.com/office/word/2003/2/auxHint";
Root. Attributes.append (XA);

Xa = doc. CreateAttribute ("xmlns", "O", w3namespace);
Xa. Value = "Urn:schemas-microsoft-com:office:office";
Root. Attributes.append (XA);

Xa = doc. CreateAttribute ("xmlns", "DT", w3namespace);
Xa. Value = "uuid:c2f41010-65b3-11d1-a29f-00aa00c14882";
Root. Attributes.append (XA);

Xa = doc. CreateAttribute ("xmlns", "space", w3namespace);
Xa. Value = "preserve";
Root. Attributes.append (XA);

Add a value to a node
System.Xml.XmlNode BODY = doc. CreateNode (System.Xml.XmlNodeType.Element, "V", "body", "urn:schemas-microsoft-com:vml");
System.Xml.XmlNode Childnode = doc. CreateNode (System.Xml.XmlNodeType.Element, "O", "T", "Urn:schemas-microsoft-com:office:office");
Childnode.innertext = "Welcome to the wonderful world of Mengxian" ";

Add to the memory tree
Body. AppendChild (Childnode);
Root. AppendChild (body);
Doc. AppendChild (root);

Add Node Declaration
System.Xml.XmlDeclaration xd = doc. Createxmldeclaration ("1.0", "UTF-8", "yes");
Doc. InsertBefore (XD, Doc. DocumentElement);

Add processing instructions
System.Xml.XmlProcessingInstruction SPI = doc. Createprocessinginstruction ("Mso-application", "progid=\" word.document\ ")";
Doc. InsertBefore (SPI, Doc. DocumentElement);

Query node
System.Xml.XmlNamespaceManager Nsmanager = new System.Xml.XmlNamespaceManager (Doc. NameTable);
Nsmanager. AddNamespace ("W", "Http://schemas.microsoft.com/office/word/2003/2/wordml");
Nsmanager. AddNamespace ("V", "urn:schemas-microsoft-com:vml");
Nsmanager. AddNamespace ("O", "Urn:schemas-microsoft-com:office:office");
System.Xml.XmlNode node = doc. selectSingleNode ("W:worddocument/v:body/o:t", Nsmanager);
Response.Write (node. InnerText);

Node. InnerText = "Welcome to the wonderful World of Mengxian": http://dotnet.aspx.cc/";

To create a CDATA node
System.Xml.XmlCDataSection Xcds = doc. Createcdatasection ("<a href= ' http://dotnet.aspx.cc/' >" Mengxian the Wonderful World "</a>");
Node. Parentnode.insertafter (Xcds, node);

Response.Write (Xcds. InnerText);

Doc. Save (Server.MapPath ("Test.xml"));
