Explain the use of JSP XML transformers.

JSP XML transformers are used to transform XML data into other formats or structures. JSP provides built-in XML tags, such as <x:parse> and <x:out>, which allows you to parse XML documents and apply XSLT (Extensible Stylesheet Language Transformations) stylesheets to transform the XML data. This can be useful when you need to present XML data in a different format or extract specific information from the XML document.
