<?xml version='1.0'?>
<!-- This file represents a fragment of a book store inventory database -->
<bookstore>
  <book genre="autobiography" publicationdate="1991" ISBN="1-861003-11-0">
  <title>The Autobiography of Benjamin Franklin</title>
  <author>
  <first-name>Benjamin</first-name>
  <last-name>Franklin</last-name>
  </author>
  <price>8.99</price>
  </book>
</bookstore>


xml文件格式如上，如何修改元素名称/如何修改属性名称/如何删除属性?,并保证xml文件的其它内容不变!

例如:如何把元素名book改为mingcheng/如何把属性名genre改为chubanshe/如何把属性publicationdate="1991"直接去掉?
得到如下效果:

<?xml version='1.0'?>
<!-- This file represents a fragment of a book store inventory database -->
<bookstore>
  <mingcheng chubanshe="autobiography" ISBN="1-861003-11-0">
  <title>The Autobiography of Benjamin Franklin</title>
  <author>
  <first-name>Benjamin</first-name>
  <last-name>Franklin</last-name>
  </author>
  <price>8.99</price>
  </mingcheng>
</bookstore>

请大家帮帮忙,谢了!

本人原创，刚刚写的。

C# code

public void EditXmlFile(){      XmlDocument xmlDoc = new XmlDocument();      xmlDoc.Load("yourFile");      XmlNode root = xmlDoc.DocumentElement;      //if (root.HasChildNodes)      //{      //  return node.ChildNodes;      //}      ///       EditNode(root, "Book", "mingcheng", xmlDoc);      xmlDoc.Save("yourFile");}private void EditNode(XmlNode node, string newName, string oldName, XmlDocument xmlDoc)    {      if(node.Name == oldName)      {        XmlNode newNode = xmlDoc.CreateNode(newName, node.LocalName, node.NamespaceURI);        foreach(XmlAttribute a in node.Attributes)        {          if (a.Name == "genre")          {            XmlAttribute newAttr = xmlDoc.CreateAttribute("chuBanShe");            newAttr.Value = a.Value;            newNode.Attributes.Append(newAttr);          }          else if(a.Name != "publicationdate")          {            newNode.Attributes.Append(a);          }        }        foreach(XmlNode n in node.ChildNodes)        {          newNode.AppendChild(n);        }        XmlNode parent = node.ParentNode;        parent.ReplaceChild(newNode, node);      }    }

调试成功。注意，当我们Append一个XMLNode时，总是取第一个Node。

C# code
  {      if (node.Name == oldName)      {        XmlNode newNode = xmlDoc.CreateNode(XmlNodeType.Element, newName, node.NamespaceURI);        XmlAttributeCollection collection = node.Attributes;        foreach (XmlAttribute a in collection)        {          if (a.Name == "genre") this.data
