1. 用MSXML COM对象解析
using MSXML2;
using System.Xml;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
MSXML2.DOMDocument xmldoc = new DOMDocument();
xmldoc.async = false;
xmldoc.load(Server.MapPath("a.xml"));
MSXML2.DOMDocument xsldoc = new DOMDocument();
xsldoc.async = false;
xsldoc.load(Server.MapPath("a.xsl"));
Response.Write(xmldoc.transformNode(xsldoc));
}
}
2. 用.Net的xml命名空间的类来解析
using System.Xml;
using System.Xml.Xsl;
using System.Xml.XPath;
using System.Text;
using System.IO;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//VS2003
XmlDocument doc = new XmlDocument();
doc.Load(Server.MapPath("a.xml"));
XmlElement root = doc.DocumentElement;
XPathNavigator navgator = root.CreateNavigator();
StringBuilder builder = new StringBuilder();
XmlWriter writer = XmlWriter.Create(builder);
XslTransform transform = new XslTransform();
transform.Load(Server.MapPath("a.xsl"));
transform.Transform(navgator, null, writer);
writer.Close();
Response.Write(builder.ToString());
}
}
using System.Xml;
using System.Xml.Xsl;
using System.Xml.XPath;
using System.Text;
using System.IO;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
//VS2005
StringBuilder builder = new StringBuilder();
XmlWriter writer = XmlWriter.Create(builder);
XslCompiledTransform transform = new XslCompiledTransform();
transform.Load(Server.MapPath("a.xsl"));
transform.Transform(Server.MapPath("a.xml"), null, writer);
writer.Close();
Response.Write(builder.ToString());
}
}
VS2005下面，也可以用另外的方法，即生成HTML的临时文件
//VS2005
XslCompiledTransform transform = new XslCompiledTransform();
transform.Load(Server.MapPath("a.xsl"));
transform.Transform(Server.MapPath("a.xml"), Server.MapPath("a.html"));
Response.WriteFile(Server.MapPath("a.html"));
3. 下载。用xslt解析xml生成网页，下载的处理是很方便的。
default.aspx如下，只是个简单的示例，服务器端没有任何代码。
<input type="button" value="Download" onclick="window.open('download.aspx','download');" />
<iframe id="download" name="download" src="" style="display:none;"></iframe>
download.aspx：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="download.aspx.cs" Inherits="download" %>
download.aspx.cs：
using System.Xml;
using System.Xml.Xsl;
using System.Xml.XPath;
using System.Text;
using System.IO;
public partial class download : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string fileName = "aaa_" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls";
string fullPath = Server.MapPath(fileName);
XmlTextWriter writer = new XmlTextWriter(fullPath, Encoding.UTF8);
XslCompiledTransform transform = new XslCompiledTransform();
transform.Load(Server.MapPath("a.xsl"));
transform.Transform(Server.MapPath("a.xml"), null, writer);
writer.Close();
Response.Clear();
Response.Buffer = true;
Response.AddHeader("Content-Disposition", "attachment; filename=" + fileName);
Response.WriteFile(fullPath);
}
}
这种方式下载，是利用了Excel可以打开html网页（其实将文件后缀名改成.doc也就可以用word打开），如果将文件存到本地，用文本编辑器打开，就可以看到，实际上下载下来的是一个html的页面文件。
下载的方式很多，这种方式有它的优点和缺点。优点是如果用xslt解析的网页，这种下载方式实现上很方便；缺点，如果下载的数据比较多文件比较大（接近2M之后），用Excel、Word打开时会很慢。
