XSL Transformations (XSLT) is yet another popular W3C specification that defines XML-based syntax, used to transform XML documents to any other text format, such as HTML, text, XML, etc. XSLT stylesheets can be applied on the source XML document to transform XML into some other XML, or text, HTML, or any other text format.

hi,

The World Wide Web Consortium (W3C) started to develop XSL because there was a need for an XML-based style sheet language.

XSLT is a language for transforming XML documents into XHTML documents or to other XML documents.

* XSLT stands for XSL Transformations
* XSLT is the most important part of XSL
* XSLT transforms an XML document into another XML document
* XSLT uses XPath to navigate in XML documents
* XSLT is a W3C Recommendation
XSLT is the most important part of XSL.

XSLT is used to transform an XML document into another XML document, or another type of document that is recognized by a browser, like HTML and XHTML. Normally XSLT does this by transforming each XML element into an (X)HTML element.

With XSLT you can add/remove elements and attributes to or from the output file. You can also rearrange and sort elements, perform tests and make decisions about which elements to hide and display, and a lot more.

A common way to describe the transformation process is to say that XSLT transforms an XML source-tree into an XML result-tree.

Yes I can geek!

Xml is a meta-markup language that provides a format for describing data. Xslt is one way to consume and transform this data into a variety different formats, including Xml, html and wml. In this article we shall learn how to transform a simple Xml document using Xslt.

The .NET framework provides rich support for the manipulation of Xml documents.

Xml Transformation steps

The steps to transform an Xml document are

1) Load the Xml document

Code:

XPathDocument myXPathDoc = new XPathDocument(<xml file path>) ;

2) Load the Xsl file

Code:

XslTransform myXslTrans = new XslTransform() ;
myXslTrans.Load(<xsl file path>);

3) Create a stream for output

Code:

XmlTextWriter myWriter = new XmlTextWriter("result.html",null) ;

4) Perform the actual transformation

Code:

myXslTrans.Transform(myXPathDoc,null,myWriter) ;

Compile and run the application. Usage is as follows:

Code:

XmlTransformUtil.exe <xml file path> <xsl file path>

C# coding is as follows,

Code:

using System ;
using System.IO ;
using System.Xml ;
using System.Xml.Xsl ;
using System.Xml.XPath ;

public class XmlTransformUtil{

    public static void Main(string[] args){
        
        if (args.Length == 2){
            
            Transform(args[0], args[1]) ;
            
            
        }else{
            
            PrintUsage() ;
            
        }
        
    
    }
    
    public static void Transform(string sXmlPath, string sXslPath){
        
        try{
            
            //load the Xml doc
            XPathDocument myXPathDoc = new XPathDocument(sXmlPath) ;

            XslTransform myXslTrans = new XslTransform() ;
            
            //load the Xsl 
            myXslTrans.Load(sXslPath) ;
            
            //create the output stream
            XmlTextWriter myWriter = new XmlTextWriter
				("result.html", null);
            
            //do the actual transform of Xml
            myXslTrans.Transform(myXPathDoc,null, myWriter);        

            myWriter.Close() ;


        }catch(Exception e){

            Console.WriteLine("Exception: {0}", e.ToString());
        }
        
    }
    
    
    public static void PrintUsage(){
        Console.WriteLine
		("Usage: XmlTransformUtil.exe <xml path> <xsl path>");
    }

}
