XHTML

XHTML (eXtensible HyperText Markup Language) is a family of XML markup languages that
mirror or extend versions of the widely-used Hypertext Markup Language (HTML), the language
in which web pages are written.
While HTML (prior to HTML5) was defined as an application of Standard Generalized Markup
Language (SGML), a very flexible markup language framework, XHTML is an application of XML,
a more restrictive subset of SGML. Because XHTML documents need to be well-formed, they can be
parsed using standard XML parsers—unlike HTML, which requires a lenient HTML-specific parser.
XHTML 1.0 became a World Wide Web Consortium (W3C) Recommendation on January 26,
2000. XHTML 1.1 became a W3C Recommendation on May 31, 2001. XHTML5 is undergoing
development as of September 2009, as part of the HTML5 specification.

Caselet PDF, HTML Files

W hat do terms such as pdf file, html, etc., mean? How does one convert these into
text files? Please explain.
S. Krishnamoorthy

A PDF file is a Portable Document Format file. It can be viewed from any PDF reader
application such as Adobe Acrobat Reader.
Any document that has to be distributed across multiple platforms will be made a PDF file
and distributed. The advantage of this is that any PDF reader is sufficient to view and print
the document and it is freely available.
If the document is sent in any other format other than the relevant application, you should
have the fonts installed. Most manuals are sent as PDF files.

An HTML file is a Hyper Text Markup Language file. It can be viewed from any Web
browser such as Internet Explorer, Netscape, etc. HTML document is used in the Internet.
You can open the HTML file in a browser and from the browser it can be saved as Text file.

For some pages, the file of text format is not the same as it appears in the browser.
Similarly a PDF file can be saved as Text Format from a PDF application such as Adobe
Acrobat. Acrobat Reader 7.0.7 full version can be downloaded from this URL: http://
www.softwarepatch.com /graphics/acrobatreader7.html
Only a PDF reader is freely available on the Internet.
If you want to create a PDF document, you will need to buy a licensed application such as
Adobe Acrobat or any third party applications.
