本asp类可以用来处理xml包的发送与接收。可用于各种异构系统之间API接口间通讯，以及处理Web Service的调用与接收。
属性：
URL : 发送xml的接收地址
String
只写
Message : 系统错误信息
String
只读
XmlNode:获取发送包XML中节点的值
String
只读
参数：Str:节点名称
GetXmlData: 获取返回XML数据对象
XMLDom
只读
方法：
LoadXmlFromFile : 从外部xml文件填充XmlDoc对象
参数 Path:xml路径
Void
LoadXmlFromString : 用字符串填充XmlDoc对象
参数 Str:xml字符串
Void
NodeValue 设置node的参数
参数
NodeName 节点名
NodeText 值
NodeType 保存类型 [text=0,cdata=1]
blnEncode 是否编码 [true,false]
Void
SendHttpData : 发送xml包
PrintSendXmlData : 打印发送请求XML数据
PrintGetXmlData : 打印返回XML数据
SaveSendXmlDataToFile : 保存发送请求xml数据到文件，文件名为sendxml_日期.txt
SaveGetXmlDataToFile : 保存返回XML数据到文件，文件名为getxml_日期.txt
GetSingleNode : 获取返回xml的节点信息
参数 Nodestring：节点名
AcceptHttpData : 接收XML包，错误信息通过Message对象获取
AcceptSingleNode: 返回接收XML包节点信息
参数 Nodestring：节点名
PrintAcceptXmlData : 打印接收端接收到的XML数据
SaveAcceptXmlDataToFile : 保存接收的XML包数据到文件，文件名为acceptxml_日期.txt
SaveDebugStringToFile : 保存调试数据到文件，文件名为debugnote_日期.txt
参数 Debugstr：调试信息
代码:
xmlcls.asp
