XSLT / XML / C# (转）这个例程展示了如何将xslt 应用于从数据库中读出的xml格式数据上. 例程完全使用C#语言编写:
using System;
using System.Collections;
using System.Data;
using System.Data.SqlClient;
using System.Xml;
using System.Xml.Xsl;
public class XsltTransform
{
public static void Transform()
{
SqlConnection nwindConn = new SqlConnection("Data
Source=INMUMIS123;database=northwind;uid=sa;pwd=;");
nwindConn.Open();
DataSet custDS = new DataSet("CustomerDataSet");
SqlDataAdapter custDA = new SqlDataAdapter("SELECT * FROM Customers",
nwindConn);
custDA.Fill(custDS, "Customers");
SqlDataAdapter ordersDA = new SqlDataAdapter("SELECT * FROM Orders",
nwindConn);
ordersDA.Fill(custDS, "Orders");
nwindConn.Close();
custDS.Relations.Add("CustOrders",
custDS.Tables["Customers"].Columns["CustomerID"],
custDS.Tables["Orders"].Columns["CustomerID"]).Nested = true;
XmlDataDocument xmlDoc = new XmlDataDocument(custDS);
XslTransform xslTran = new XslTransform();
xslTran.Load("transform.xsl");
// This is for generating the output in new html
XmlTextWriter writer = new XmlTextWriter("xslt_output.html",
System.Text.Encoding.UTF8);
writer.Close();
// This is for writing in the current page
xslTran.Transform(xmlDoc, null, Response.OutputStream);
}
}
上面这个称为XsltTransform的类连接到一个数据库,将数据填充到XmlDocument 中,然后将下面提供的Xslt应用于这个XML.

}
public void Transform()
{
SqlConnection nwindConn = new SqlConnection("Data

nwindConn.Open();
DataSet custDS = new DataSet("CustomerDataSet");
SqlDataAdapter custDA = new SqlDataAdapter("SELECT * FROM Customers",
nwindConn);
custDA.Fill(custDS, "Customers");
SqlDataAdapter ordersDA = new SqlDataAdapter("SELECT * FROM Orders",
nwindConn);
ordersDA.Fill(custDS, "Orders");
nwindConn.Close();
custDS.Relations.Add("CustOrders",
custDS.Tables["Customers"].Columns["CustomerID"],
custDS.Tables["Orders"].Columns["CustomerID"]).Nested = true;
XmlDataDocument xmlDoc = new XmlDataDocument(custDS);
XslTransform xslTran = new XslTransform();
xslTran.Load("transform.xsl");
// XmlTextWriter writer = new XmlTextWriter("xslt_output.html",
System.Text.Encoding.UTF8);
xslTran.Transform(xmlDoc, null, Response.OutputStream);
// writer.Close();
}
</script>
<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
</form>
</body>
</HTML>
上面的aspx page 用这个类(XsltTranform)建立了一对象, 然后调用了Transform 函数
。
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="CustomerOrders">
<STYLE>
BODY {font-family:verdana;font-size:9pt}
TD {font-size:8pt}
</STYLE>
<TABLE BORDER="1">
<xsl:apply-templates select="Customers"/>
</TABLE>
</xsl:template>
<xsl:template match="Customers">
<TR><TD>
<xsl:value-of select="ContactName"/>, <xsl:value-of select="Phone"/><BR/>
</TD></TR>
<xsl:apply-templates select="Orders"/>
</xsl:template>
<xsl:template match="Orders">
<TABLE BORDER="1">
<TR><TD valign="top"><B>Order:</B></TD><TD valign="top"><xsl:value-of select="OrderID"/></TD></TR>
<TR><TD valign="top"><B>Date:</B></TD><TD valign="top"><xsl:value-of select="OrderDate"/></TD></TR>
<TR><TD valign="top"><B>Ship To:</B></TD>
<TD valign="top"><xsl:value-of select="ShipName"/><BR/>
<xsl:value-of select="ShipAddress"/><BR/>
<xsl:value-of select="ShipCity"/>, <xsl:value-of select="ShipRegion"/> <xsl:value-of select="ShipPostalCode"/><BR/>
<xsl:value-of select="ShipCountry"/></TD></TR>
</TABLE>
</xsl:template>
</xsl:stylesheet>
最后是这个xslt 文件
