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【孟宪会之精彩世界】";
//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.Create
xmlDeclaration("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【孟宪会之精彩世界】:http://dotnet.aspx.cc/";
//
创建CDATA节点
System.
xml.
xmlCDataSection xcds = doc.CreateCDataSection("<a href='http://dotnet.aspx.cc/'>【孟宪会之精彩世界】</a>");
node.ParentNode.InsertAfter(xcds, node);
Response.Write(xcds.InnerText);
doc.Save(Server.MapPath("test.
xml"));
