在asp.net中读取XML文件信息的4种方法
方法一 ：使用XML控件
<% @ Page Language="C#"%>
<html>
<body>
<h3><font face="Verdana">读取XML方法一</font></h3>
<from runat=server>
<asp:Xml id="xml1" DocumentSource="grade.xml" runat="server" />
</from>
</body>
</html>
方法二： 使用DOM技术
<% @ Page Language="C#"%>
<% @ Import Namespace="System.Xml"%>
<% @ Import Namespace="System.Xml.Xsl"%>
<html>
<script language="C#" runat="server">
void Page_Load(Object sender,EventArgs e)
{
XmlDocument doc=new XmlDocument();
doc.Load(Server.MapPath("grade.xml"));
xml1.Document=doc;
}
</script>
<body>
<h3><font face="Verdana">读取XML方法二</font></h3>
<from runat=server>
<asp:Xml id="xml1" runat="server" />
</from>
</body>
</html>
方法三 ：使用DataSet对象
<% @ Page Language="C#"%>
<% @ Import Namespace="System.Data"%>
<% @ Import Namespace="System.Data.OleDb"%>
<script language="C#" runat="server">
void Page_Load(Object sender,EventArgs e)
{
DataSet objDataSet=new DataSet();
objDataSet.ReadXml(Server.MapPath("grade.xml"));
dgEmployees.DataSource=objDataSet.Tables["student"].DefaultView;
dgEmployees.DataBind();
}
</script>
<body>
<h3><font face="Verdana">读取XML方法三</font></h3>
<asp:DataGrid id="dgEmployees" runat="server" />
</body>
</html>
方法四 ：按文本方式读取
<% @ Page Language="C#"%>
<% @ Import Namespace="System.Xml"%>
<html>
<script language="C#" runat="server">
private void Page_Load(Object sender,EventArgs e)
{
XmlTextReader objXMLReader=new XmlTextReader(Server.MapPath("grade.xml"));
string strNodeResult="";
XmlNodeType objNodeType;
while(objXMLReader.Read())
{
objNodeType =objXMLReader.NodeType;
swith(objNodeType)
{
case XmlNodeType.XmlDeclaration:
//读取XML文件头
strNodeResult+="XML Declaration:<b>"+objXMLReader.Name+""+objXMLReader.Value+"</b><br/>";
break;
case XmlNodeType.Element:
//读取标签
strNodeResult+="Element:<b>"+objXMLReader.Name+"</b><br/>";
break;
case XmlNodeType.Text:
//读取值
strNodeResult+=" -Value:<b>"+objXMLReader.Value+"</b><br/>";
break;
}
//判断该节点是否有属性
if(objXMLReader.AttributeCount>0)
{ //用循环判断完所有节点
while(objXMLReader.MoveToNextAttibute)
{ //取标签和值
strNodeResult+=" -Attribute:<b>"+objXMLReader.Name+"</b> value:<b>"+objXMLReader.Value+"</b><br/>";
}
}
LblFile.Text=strNodeResult;
}
}
</script>
<body>
<h3><font face="Verdana">读取XML方法四</font></h3>
<from runat=server>
<asp:label id="LblFile" runat="server" />
</from>
</body>
</html>
