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
