Clarion is a commercial, 4GL, object-oriented, programming language and Integrated Development Environment from SoftVelocity used to program database applications. It is compatible with ISAM, SQL and ADO data access methods, reads and writes several flat file desktop database formats including ASCII, CSV, DOS, FoxPro, Clipper, dBase, or all SQL RDBMS databases via ODBC, MS SQL Server, Sybase SQL_Anywhere and Oracle through the use of accelerated native database drivers, and XML, Clarion can be used to output to HTML, XML, plaintext, and PDF, among others. One of the Clarion Development Environment's primary features is its use of "templates" which are used in conjunction with a code generator to produce much of the repetitive, time consuming code that is typically required when producing an application. An "embeditor" shows the developer the code that will be generated and embed points where the developer can enter their own hand-code in the context of the template generated code. Advanced Clarion programmers can create their own templates, or edit the existing ones.
Except the article forming the main content most HTML documents on the WWW contain additional contents such as navigation menus, design elements or commercial banners. In the context of several applications it is necessary to draw the distinction between main and additional content automatically. Content extraction and template detection are the two approaches to solve this task. This book gives an extensive overview and detailed description of existing and newly developed algorithms from both areas. The described content extraction algorithms are evaluated under different aspects using objective performance measures. An analysis of methods to cluster web documents according to their underlying templates completes the book. In combination with a localised crawling process this clustering analysis can be used to automatically create sets of training documents for template detection. As the whole process can be automated it allows to perform template detection on a single document, thereby combining the advantages of single and multi document algorithms.
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The web document distinction emphasizes the fact that not all content generated by a web template system, web service, and other related systems represents output as a web page. The e-mail protocols predate the Web protocols, but are not a subset, they constitute distinct Internet services. E-mail documents may be HTML documents, and may be viewed into a e-mail client or through a webmail (or Internet forum) as a web page. A lot of web applications deal with web page bodies and e-mail bodies indistinctly. Web applications deal with web pages, but also with many other formats and protocols. Another extended (derived) concept is dynamic web document, like documents generated from template engines or web services. Dynamic web page is a specific case of dynamic web document. Common Gateway Interface(CGI)is a concept used to create dynamic web documents.
This book is about oPage, a framework for developing Web based content management systems. The robust infrastructure, the versatile template engine, the structured backend and the provided modules and controls make oPage a good foundation for Web sites. The author Hannes Dorn provides background information on Internet, Hypermedia and WWW. He describes Web content management and what kind of functions are provided by such systems. Classification criterias are defined and related approaches like TYPO3, Drupal, Joomla! and EZ Publish are shown. The oPage framework is described in detail and samples are provided. He also gives an outlook on potential future extensions. This book is a technical reference and is intended for HTML Designers with technical background and Web software developers.
Practical Node.js is your step-by-step guide to learning how to build a wide range of scalable real-world web applications using a professional development toolkit. Node.js is an innovative and highly efficient platform for creating web services. But Node.js doesn't live in a vacuum! In a modern web development, many different components need to be put together - routing, database driver, ORM, session management, OAuth, HTML template engine, CSS compiler and many more.If you already know the basics of Node.js, now is the time to discover how to bring it to production level by leveraging its vast ecosystem of packages. As a web developer, you'll work with a varied collection of standards and frameworks - Practical Node.js shows you how all those pieces fit together.Practical Node.js takes you from installing all the necessary modules to writing full-stack web applications by harnessing the power of the Express.js and Hapi frameworks, the MongoDB database with Mongoskin and Mongoose, Jade and Handlebars template engines, Stylus and LESS CSS languages, OAuth and Everyauth libraries, and the Socket.IO and Derby libraries, and everything in between. The book also covers how to deploy to Heroku and AWS, daemonize apps, and write REST APIs. You'll build full-stack real-world Node.js apps from scratch, and also discover how to write your own Node.js modules and publish them on NPM. You already know what Node.js is, now learn what you can do with it and how far you can take it!
After years of anticipation and delay, the W3C finally released the XSLT 2.0 standard in January 2007. The revised edition of this classic book offers practical, real-world examples that demonstrate how you can apply XSLT stylesheets to XML data using either the new specification, or the older XSLT 1.0 standard.XSLT is a critical language for converting XML documents into other formats, such as HTML code or a PDF file. With XSLT, you get a thorough understanding of XSLT and XPath and their relationship to other web standards, along with recommendations for a honed toolkit in an open platform-neutral, standards-based environment. This book:- Covers the XSLT basics, including simple stylesheets and methods for setting up transformation engines- Walks you through the many parts of XSLT, particularly XSLT's template-based approach to transformations- Applies both XSLT 1.0 and 2.0 solutions to the same problems, helping you decide which version of XSLT is more appropriate for your project- Includes profuse examples that complement both the tutorial and the reference materialThe new edition of XSLT has been updated thoroughly to explain XSLT 2.0's many dependencies, notably XML Schema and XPath 2.0. Want to find out how the 2.0 specification improves on the old? This book will explain.
