XHTML and XSLT

[lakshmi pramod]

what is the difference between XHTML and XSLT ?

[Pho Tek]

XHTML is purely HTML4.01 rewritten to make HTML documents well formed XML documents.
XSLT is a language to transform XML trees to different XML trees and possibly different rendering outputs e.g. aural, PDF (via XSL-FO) or mobile devices.

[Khun Yee Fung]

More specifically, XHTML 1.0 is HTML 4.0 in XML. XSLT, on the other hand, is a programming language that transforms XML documents into other documents, whether they are XML, HTML, or text.
XSL Formatting objects (XSL-FO, or simply XSL) is an entirely different animal: it is a markup language for the description of document layouts. You can think of it as Postscript without the programming primitives. It is almost like PDF but of course it is not a final format. PDF is a final format for documents; documents in a final format are not supposed to change much.

I forgot to mention that after you have generated an XSL document, you still have to render it into something much smaller in size. In other words, you want to render the XSL file into a document using a final format (e.g., PDF, PS, ASCII, HTML).
This is analogous to rendering SVG documents into GIF or JPEG images when you have to transmit the images described by the SVG documents over a network.

Thank you for the explanations .
What is Xpath ?
Is XPath and XSLT similar in the sense they have the same purpose or are they complementary to each other?

XPath: XPath processor is to locate elements in the XML file by path name.
There are a number of free XML parsers as u can run from the command line: Xalan, XT, XML4J, Saxon etc they all serve same purpose, transforming XML document into other document.
So Xpath and XSLT are different.
Hope this helps...
