Just Another Perl Hack Neil Bowers1 Canon Research Centre Europe
Weblint: Just Another Perl Hack Neil Bowers1 Canon Research Centre Europe Abstract Weblint is a utility for checking the syntax and style of HTML pages. It was inspired by lint [15], which performs a similar function for C and C++ programmers. Weblint does not aspire to be a strict SGML validator, but to provide helpful comments for humans. The importance of quality assurance for web sites is introduced, and one particular area, validation of HTML, is described in more detail. The bulk of the paper is devoted to weblint: what it is, how it is used, and the design and implementation of the current development version. 1. Introduction The conclusion opens with a summary of the information and opinions given in this paper. A Web sites are becoming an increasingly critical part of selection of the lessons learned over the last four years how many companies do business. For many companies is given, followed by plans for the future, and related web sites are their business. It is therefore critical that ideas. owners of web sites perform regular testing and analysis, to ensure quality of service. 2. Web Site Quality Assurance There are many different checks and analyses which The following are some of the questions you should be you can run on a site. For example, how usable is your asking yourself if you have a web presence. I have site when accessed via a modem? An incomplete list of limited the list to those points which are relevant to similar analyses are given at the start of Section 2. -

HTML - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/HTML HTML From Wikipedia, the free encyclopedia HyperText Markup Language ( HTML ) is the main HTML markup language for displaying web pages and other (HyperText Markup Language) information that can be displayed in a web browser. Filename .html, .htm HTML is written in the form of HTML elements extension consisting of tags enclosed in angle brackets (like <html> ), within the web page content. HTML tags most Internet text/html commonly come in pairs like <h1> and </h1> , although media type some tags, known as empty elements , are unpaired, for Type code TEXT example <img> . The first tag in a pair is the start tag , the second tag is the end tag (they are also called opening Uniform Type public.html tags and closing tags ). In between these tags web Identifier designers can add text, tags, comments and other types of Developed by World Wide Web Consortium & text-based content. WHATWG The purpose of a web browser is to read HTML Type of Markup language documents and compose them into visible or audible web format pages. The browser does not display the HTML tags, but Extended SGML uses the tags to interpret the content of the page. from HTML elements form the building blocks of all websites. Extended to XHTML HTML allows images and objects to be embedded and Standard(s) can be used to create interactive forms. It provides a ISO/IEC 15445 means to create structured documents by denoting W3C HTML 4.01 structural semantics for text such as headings, paragraphs, (http://www.w3.org/TR/1999 lists, links, quotes and other items. -

The motivation comes from new end-user requirements for web applications: demand for higher interaction, adaptation for mobile and multimodal usage, and rich multimedia content. At the same time, there is a requirement for non- programmers to be able to author, customize, and maintain web user interfaces. -

Mathematical Markup Language (Mathml) Version 2.0
Mathematical Markup Language (MathML) Version 2.0 W3C Working Draft 28 March 2000 This version: http://www.w3.org/TR/2000/WD-MathML2-20000328 Also available as: HTML zip archive, XHTML zip archive, XML zip archive, PDF (screen), PDF (paper) Latest version: http://www.w3.org/TR/MathML2 Previous versions: http://www.w3.org/TR/2000/WD-MathML2-20000211 http://www.w3.org/TR/1999/WD-MathML2-19991222 http://www.w3.org/TR/1999/WD-MathML2-19991201 Editors: Nico Poppelier (Penta Scope) Robert Miner (Geometry Technologies, Inc.)

Abstract This specification defines the Mathematical Markup Language, or MathML. MathML is an XML application for de- scribing mathematical notation and capturing both its structure and content. The goal of MathML is to enable mathe- matics to be served, received, and processed on the World Wide Web, just as HTML has enabled this functionality for text. This specification of the markup language MathML is intended primarily for a readership consisting of those who will be developing or implementing renderers or editors using it, or software that will communicate using MathML as a protocol for input or output. It is not a User’s Guide but rather a reference document. This document begins with background information on mathematical notation, the problems it poses, and the philos- ophy underlying the solutions MathML proposes. -
HTML 4.0 Specification
HTML 4.0 Specification REC-html40-19980424 HTML 4.0 Specification W3C Recommendation, revised on 24-Apr-1998 This version: http://www.w3.org/TR/1998/REC-html40-19980424 Latest version: http://www.w3.org/TR/REC-html40 Previous version: http://www.w3.org/TR/REC-html40-971218 Editors: Dave Raggett <[email protected]> Arnaud Le Hors <[email protected]> Ian Jacobs <[email protected]> Abstract This specification defines the HyperText Markup Language (HTML), version 4.0, the publishing language of the World Wide Web. In addition to the text, multimedia, and hyperlink features of the previous versions of HTML, HTML 4.0 supports more multimedia options, scripting languages, style sheets, better printing facilities, and documents that are more accessible to users with disabilities. HTML 4.0 also takes great strides towards the internationalization of documents, with the goal of making the Web truly World Wide. HTML 4.0 is an SGML application conforming to International Standard ISO 8879 -- Standard Generalized Markup Language [ISO8879] [p.327] . Status of this document This document has been reviewed by W3C Members and other interested parties and has been endorsed by the Director as a W3C Recommendation. It is a stable document and may be used as reference material or cited as a normative reference from another document. W3C’s role in making the Recommendation is to draw attention to the specification and to promote its widespread deployment. This enhances the functionality and interoperability of the Web. W3C recommends that user agents and authors (and in particular, authoring tools) produce HTML 4.0 documents rather than HTML 3.2 documents (see [HTML32] [p.329] ).
