In Mozilla develop center, we can see the following articles: Http://developer.mozilla.org/en/docs/The_XSLT/JavaScript_Interface_in_ Gecko:basic_example
First, you need to know how to dynamically load XML files, either with XMLDOM objects or with XMLHttpRequest, Responsexml objects, where I use XMLHttpRequest.

The way to load XSLT in JavaScript is as follows:
1. Use XMLDOM or XMLHttpRequest to load XML and XSLT.
2. Use Xsltprocessor.importstylesheet to introduce XSLT.
3. Use the Xsltprocessor.transformtofragment method to convert it into DOM fragment. Then append or insert the fragment element of the DOM using AppendChild or InsertBefore.
Sample code
var ownerdocument = document.implementation.createDocument ("", "test", null);
var newfragment = processor.transformtofragment (domtobetransformed, ownerdocument);
Of course, you can use Transformtodocument.
var newdocument = processor.transformtodocument (domtobetransformed);
It should be noted that the converted node is an element or a fragment, so you can use the Obj.innerhtml=new Document by following the serialization
4. Serialization.
(New XMLSerializer ()). Serializetostring (NewDocument)
5. In IE, you can use the Xmldom method, Xmldoc.transformnode (Xsldocument) method to carry on the conversion.

First, we first create an XML file and an XSLT file to facilitate the explanation later.
