创建、查询、修改带名称空间的 XML 文件的例子

作者:佚名    文章来源:不详    更新时间:2007-6-5 0:28:52

XML的应用越来越广泛了,如Vista、Flex编程都将使用 XML,正确掌握XML的各种操作,对提高编程效率至关重要。下面就是一个综合处理带名称空间的XML的例子。

C#:


string w3NameSpace = "http://www.w3.org/2000/xmlns/";

System.Xml.XmlDocument doc = new System.Xml.XmlDocument();

 

//创建根节点

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);

 

//为节点添加属性

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);

 

//为节点增加值

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 = "欢迎光临【精彩世界】";

 

//添加到内存树中

body.AppendChild(childNode);

root.AppendChild(body);

doc.AppendChild(root);

 

//添加节点声明

System.Xml.XmlDeclaration xd = doc.CreateXmlDeclaration("1.0", "UTF-8", "yes");

doc.InsertBefore(xd, doc.DocumentElement);

 

//添加处理指令

System.Xml.XmlProcessingInstruction spi = doc.CreateProcessingInstruction("mso-application", "progid=\"Word.Document\"");

doc.InsertBefore(spi, doc.DocumentElement);

 

//查询节点

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 = "欢迎光临【精彩世界】:http://dotnet.aspx.cc/";

 

//创建CDATA节点

System.Xml.XmlCDataSection xcds = doc.CreateCDataSection("【精彩世界】");

node.ParentNode.InsertAfter(xcds, node);

 

Response.Write(xcds.InnerText);

 

doc.Save(Server.MapPath("test.xml"));

xa = doc.CreateAttribute("xmlns", "v", w3NameSpace)

root.Attributes.Append(xa)

xa = doc.CreateAttribute("xmlns", "w10", w3NameSpace)

xa.Value = "urn:schemas-microsoft-com:office:word"

Dim xcds As System.Xml.XmlCDataSection = doc.CreateCDataSection("【精彩世界】")

node.ParentNode.InsertAfter(xcds, node)

Response.Write(xcds.InnerText)
