这是一个把数据库里的数据生成XML格式,你稍微改一下就可以用在文本文件了。

用C#来做。要用XmlTextWriter向TXT文件中写内容。
using System.Xml;
using System.Text;
XmlTextReader xmlReader = null;
xmlReader = new XmlTextReader(mDocument); //mDocument参数为xml文档名字
while(xmlReader.Read())
{
if(xmlReader.NodeType == XmlNodeType.Element)
{
while(xmlReader.MoveToNextAttribute())
{
//用XmlTextWriter类将xmlReader.Name和xmlReader.Value写入HTML做
//相应的处理
}
if(xmlReader.IsEmptyElement)
{
}
else
{
}
}
else if(xmlReader.NodeType == XmlNodeType.EndElement)
{
//做自己的处理
}
else if(xmlReader.NodeType == XmlNodeType.Text)
{
if (xmlReader.Value.Length != 0)
{
//将xmlReader.Value 写入TXT中的处理
}
}
} //end of ~while(xmlReader.Read())
