## XSLT = XSL Transformations XSLT is the most important part of XSL. XSLT is used to transform one XML document into another XML document, or other types of documents that can be recognized by browsers, such as HTML and XHTML. Usually, XSLT accomplishes this by transforming each XML element into an (X)HTML element. With XSLT, you can add elements and attributes to the output file, or remove elements and attributes from the output file. You can also rearrange and sort elements, perform tests and decide which elements to hide or display, etc. A common way to describe the transformation process is that **XSLT transforms the XML source tree into the XML result tree**. * * * ## XSLT Uses XPath XSLT uses XPath to find information in XML documents. XPath is used to navigate through elements and attributes in XML documents. If you want to learn XPath first, please visit our (#). * * * ## How Does It Work? In the transformation process, XSLT uses XPath to define parts of the source document that match one or more predefined templates. Once a match is found, XSLT transforms the matching part of the source document into the result document. * * * ## XSLT is a W3C Standard XSLT became a W3C standard on November 16, 1999.
