Extending XSLT using C# 使用自定義函數

在xslt中用自定義的函數

1. xml文件不變

2. xslt文件要聲明一個namespace，2種引用，select和非select需要加{}，注意加""

3 隨便聲明一個類

4 transform函數要使用一個argumentlist的AddExtensionObject,指定上面的Namespace（就關聯起來了）

<?xml version="1.0" encoding="utf-8" ?>
<Employees>
  <Employee>
    <FirstName>Pierre-Emmanuel</FirstName>
    <LastName>Dautreppe</LastName>
  </Employee>
</Employees>

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
                xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:myUtils="pda:MyUtils">
  <xsl:template match="/Employees">
    <Employees>
      <xsl:for-each select="Employee">
        <Employee>
          <xsl:value-of select="myUtils:FormatName(FirstName,LastName)" />
        </Employee>
        <br></br>
        <a href ="{myUtils:GetLink()}default.aspx">abc.com</a>
      </xsl:for-each>
    </Employees>
  </xsl:template>
</xsl:stylesheet>

public class MyXslExtension
{
    public string FormatName(string firstName,string name)
    {
        return name + ", " + firstName;
    }
    public string GetLink()
    {
        return "http://www.anypromo.com/";
    }
}

           XsltArgumentList arguments = new XsltArgumentList();

            arguments.AddExtensionObject("pda:MyUtils", new MyXslExtension());

            StringWriter output = new StringWriter();
            XslCompiledTransform transform = new XslCompiledTransform();
            transform.Load(Server.MapPath("a.xslt"));
            transform.Transform(Server.MapPath("a.xml"), arguments, output);
            Response.Write(output.ToString());
