迭代函数思路：
1.每个xml文件时有无数个兄弟节点组成，但是终有最后截止的一个，那么循环结束的标志就是当一个节点没有兄弟节点时，循环就结束，
那么可以循环兄弟节点，于是有循环兄弟节点函数
2每个节点可能有子节点，子节点也可能有兄弟子节点，这个时候利用循环兄弟节点函数，循环节点的第一个子节点，
效果图：
主要代码：
private void getXMLStr(Xmldocument xmlDoc) { foreach (XmlNode node in xmlDoc.ChildNodes) { if (node.NodeType == XmlNodeType.Element) { getNext(node,0); } else { xml = "" + node.OuterXml.Replace("<","<").Replace(">",">"); } } } private void getNext(XmlNode node,int i) { if (node.NextSibling == null)//如果没有兄弟节点 { if (node.HasChildNodes) { //如果有子节点 if (node.FirstChild.NodeType != XmlNodeType.Text) { //getXmlAttribute(node) 获取节点的所有属性 //如果子节点的子节点不是text类型 xml = xml + "
<" + node.Name +" "+ getXmlAttribute(node) + ">
"; getNext(node.FirstChild, i + 1); xml = xml + ""; } else { //如果子节点的子节点不是text类型 xml = xml + "" + node.OuterXml.Replace("<", "<").Replace(">", ">") + "
