XML操作的再次封装，制作简化XML文件操作步骤的控件。

最近发现操作XML比较多&＃xff0c;并且操作方式都差不多&＃xff0c;也就是读、编、删的问题&＃xff0c;所以对XML操作再次封装&＃xff0c;做了一个ControllerXML.cs.dll&＃xff0c;这样一来下次引入DLL&＃xff0c;就可以省略去很多麻烦的问题&＃xff0c;整体来讲还比较有用&＃xff0c;但XML文档结构比较固定&＃xff0c;耦合度还是比较高&＃xff0c;不利于扩展&＃xff0c;不过我对XML的大部分操作也没有那么复杂&＃xff0c;暂且就这样吧&＃xff1a;

类名&＃xff1a;

CXML.ControllerXML

成员方法&＃xff1a;
public ArrayList GetAllXMLNodes(string path,string fatherNodes,string sonNodes, string attribute,string nodes)
public void AddXMLNode(string path, string fatherNodes, string sonNodes, string[] attribute, string[] attributeValue, string[] nodes, string[] nodesValue)
public void DelXMLNode(string path, string fatherNodes, string sonNodes, string attribute, string attributeValue)
public void EditXMLNode(string path, string fatherNodes, string sonNodes, string attribute, string attributeValue, string newAttributeValue)
public void EditXMLNode(string path, string fatherNodes, string sonNodes, string attribute, string attributeValue, string nodes, string newAttributeValue)
