Transform XML using XSLT

Use XslTransform class in System.Xml.Xsl ;

 

Original XML(testCases.xml):

<?xml version="1.0" encoding="utf-8" ?>
<testcases>
    <testcase id="001" bvt="yes">
        <inputs>
            <arg1>red</arg1>
            <arg2>blue</arg2>
        </inputs>
        <expected>purple</expected>
    </testcase>
</testcases>

Transformed XML(transformed.xml):

<?xml version="1.0" encoding="utf-8"?>
<allOfTestCases>
  <aCase caseID="001">
    <bvt>yes</bvt>
    <expRes>purple</expRes>
    <inputs>
      <input1>red</input1>
      <input2>blue</input2>
    </inputs>
  </aCase>
</allOfTestCases>

XSLT file(transformer.xslt):

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>
    <xsl:output method="xml" indent="yes"/>

    <xsl:template match="/">
        <allOfTestCases>
            <xsl:for-each select="//testcase">
                <aCase>
                    <xsl:attribute name ="caseID">
                        <xsl:value-of select ="@id"/>
                    </xsl:attribute>
                    <bvt>
                        <xsl:value-of select ="@bvt"/>
                    </bvt>
                    <expRes>
                        <xsl:value-of select ="expected"/>
                    </expRes>
                    <inputs>
                        <xsl:for-each select ="inputs">
                            <input1>
                                <xsl:value-of select ="arg1"/>
                            </input1>
                            <input2>
                                <xsl:value-of select ="arg2"/>
                            </input2>
                        </xsl:for-each>
                    </inputs>
                </aCase>
            </xsl:for-each>
        </allOfTestCases>
    </xsl:template>
</xsl:stylesheet>

Program.cs:

using System;
using System.Collections.Generic;
using System.Xml.Xsl ;

namespace TransformXML
{
    class Program
    {
        static void Main(string[] args)
        {
            
            Console.WriteLine("Start Transform!");
            XslTransform xst = new XslTransform();
            xst.Load ("..\\..\\transformer.xslt");
            xst.Transform("..\\..\\testCases.xml", "..\\..\\transformed.xml");
            Console.WriteLine("Done");
        }
    }
}
