Locate specific sections of your XML documents with XPath, Part 2
Part 1 of this tutorial gave you a foundational understanding of XPath. Using slash notation, wildcards, unions, and simple text, you learned how to locate elements and attributes anywhere within an XML document. However, sometimes you need more than just matching based on the name of a node. Predicates give you advanced and refined searching capabilities, allowing you to evaluate the values of attributes and the parent and child nodes of a targeted element. Rather than find a wider node set and refine or filter that set programmatically, you can add predicates to your XPaths to find exactly the nodes you want. |

Locate specific sections of your XML documents with XPath, Part 1
XML is a data format concerned primarily with compatibility and flexibility. But
as useful as XML is, it's limited without the abilities to find specific portions of a
document quickly and to filter and selectively locate data within a document. XPath
provides the ability to easily reference specific text, elements, and attributes within
a document -- and with a fairly low learning curve. Additionally, XPath is key to many other XML vocabularies and technologies, such as XSL and XQuery. This tutorial will teach you the fundamentals of XPath, including all of its various selectors and semantics, in an example-driven and hands-on manner. |

Use JRuby on Rails and XML to supercharge Ajax with a Java Application Server
The Ruby on Rails framework has handy XML features that will make developing
with and serving database data in XML format to your JavaScript applications easier
than ever. JavaScript also has built-in XML parsing capabilities that make it a snap
to receive and parse data in XML format. But what if you now want to hook into Java
applications without having to deploy another server? That's where JRuby comes in.
JRuby on Rails is the Java implementation of the Ruby on Rails framework and brings the benefits of Rails to Java programming by allowing deployment of Ruby apps to Java application servers. In this tutorial, you'll develop a JRuby on Rails application deployable to a Java application server that will serve database data in XML format to an Ajax client that you'll build for film lovers to manage their online films database. You'll also deploy a couple of Java Server Pages pages on the same Java application server to assist the Ajax client in adding and updating films. |

Implement Semantic Web standards in your Web site
With Yahoo's recent announcement that they will implement support of
Semantic Web standards in their search engine, the benefits that the Semantic Web
has for your site have never been clearer. In addition to the existing benefits such as your structured content giving you a free, open-ended API, you now get the opportunity for increased search rankings, and more importantly, increased relevance because the search engine can better understand what the content of your site is about. In this tutorial you will learn to implement a simple social networking site using PHP and MySQL, which will implement Semantic Web standards such as hCard and Friend of a Friend (FOAF) as part of a semantic Uniform Resource Identifier (URI) scheme. |

Schema-aware processing with XSLT 2.0
With the release of version 2.0, XSLT now allows you to design your stylesheets to
be schema-aware. A schema-aware XSLT system offers many benefits, including the
ability to validate input trees prior to the XSLT transformation to ensure that the
XSLT stylesheet only processes valid input, as well as the ability to validate output trees to ensure that the XSLT transformation is producing the valid XML output. You are also able to specify data types for variables, for input parameters for user-defined functions and templates, and for return values from the functions. In this article, learn more about the concept of schema-aware facilities and follow some examples that illustrate the benefits. |

Scala and XML
Scala is a popular new programming language that runs on the Java Virtual Machine (JVM.) Scala compiles into byte-code and thus it can leverage the Java programming language. Its syntax, however, makes it a powerful alternative to Java in certain scenarios. One of those scenarios is XML processing. Scala lets you navigate and process parsed XML in several ways. It also has first class support for XML built right in, so there is no need to create strings of XML or programmatically build DOM trees. In this article, you will see these aspects of Scala in action and see how Scala can make working with XML a joy to do. |

were ever assigned to maintain, improve, and redesign. Unfortunately, in
the real world, you're often forced to take on a site someone else
designed or constructed. |

Create your own information space with Ajax and del.icio.us
del.icio.us is a social bookmarking Web site that allows users to create and
share browser-independent bookmarks, accessible directly over the Internet, in ways
your browser won't allow. The traditional hierarchical organization of browser bookmarks is overhauled, allowing users to instead associate each and every bookmark with any number of descriptive tags. Imagine a single page where you and your friends can surf the Web and have your del.icio.us tags, links, and functions handy, or a single page where you can save the site you're browsing directly into your del.icio.us account, along with comments and chosen tags. This tutorial shows you how to use Ajax to build just such a page using a PHP script as the server-side proxy. |

Create an Ajax mindreader application with E4X and Prototype, Part 2: Make the mindreader smarter
In this two-part article series, you learn to use both ECMAScript for XML
(E4X) and the Prototype JavaScript library to create a simple Ajax mindreader
application that plays Twenty Questions and learns about new objects as it goes
along. In Part 1, you learned to create a system that takes an existing
knowledge base and analyzes it to determine what the user might be thinking. Now in
Part 2, you'll learn to add new information to the knowledge base, and to use the
Prototype JavaScript library to integrate the Twenty Questions application with an
external database so training by one user is usable by others who play the game. |

Create an Ajax mindreader application with E4X and Prototype, Part 1: Build the Twenty Questions infrastructure
XML seems like a natural format for passing Ajax data. However, to work with
XML in JavaScript using the Document Object Model (DOM) is not always the best way to handle this kind of
data. This has given rise to other choices, such as JSON, which provide a more
object-like feel for developers. Now ECMAScript for XML (E4X) combines many of the
best features of the DOM with extremely easy data binding to provide a more
straightforward way to deal with XML in the browser. In this two-part article
series, you'll learn to use both E4X and the Prototype JavaScript library to create
a simple Ajax mindreader application that plays Twenty Questions and learns about new objects as it goes along. Part 1 shows you how to create a system that takes an existing knowledge base and analyzes it to determine what the user may be thinking. |

RESTful SOA using XML
Service Oriented Architecture usually implies heavyweight technology for large
enterprises. The advantages of the SOA architectural pattern also apply to smaller
environments. To follow SOA principles, you don't necessarily need all the overhead that
is useful in larger environments. You can use lightweight principles like REST to do so. This article describes how.

Aggregate RSS and Atom information using XQuery
XQuery makes it much easier to merge and filter information from XML documents
when you embed the filtering instructions right into the document that you use to
generate the output format. You can use that functionality to aggregate information
from RSS and Atom feeds into the format you need. In this article, look at the
structure of the RSS and Atom formats and how XQuery can simplify the display of that information. |

Receive events from XMLBeans
XMLBeans is a great XML-to-Java data-binding technology, but it lacks the ability to register observers for model changes. However, you can customize generated plain old Java objects (POJOs) to include the necessary interfaces and the notification of changes. Create a Sudoku Rich Client Platform (RCP) game application in Eclipse, and learn how to use eventing to validate the user's input. |

Build a customizable RSS feed aggregator in PHP
RSS (Rich Site Summary, RDF Site Summary, or Really Simple Syndication) has
been around since the mid-1990s. Over the years, several variants of the RSS format
have popped up and several claims have been made about its ownership. Despite these
differences, RSS never ceased to serve its usefulness in distributing Web content
from one Web site to many others. The popularity of RSS gave way to the growth of a
new class of Web software called the feed reader, also known as the feed aggregator.
Although there are several commercially available feed aggregators, it's easy to
develop your own feed aggregator, which you can integrate with your Web
applications. You'll appreciate this article's fully functional PHP code snippets,
demonstrating the use of PHP-based server-side functions to develop a customizable
RSS feed aggregator. In addition, you'll reap instant benefits from using the fully
functional RSS feed aggregator code, which you can download from this article. |

support, which means that XML data is stored and queried in its inherent hierarchical format.
To query XML data, DB2 offers two languages, SQL/XML and XQuery. Additionally,
DB2 9 has sophisticated XML indexing capabilities and support for XML Schema
validation. While most existing performance guidelines for DB2 also apply to
XML data, this article provides additional XML-specific performance tips.

Create dynamic Firefox user interfaces
When you create browser-based applications that display XML data feeds, you
often need to code the data-retrieval mechanism and the user interface. Mozilla
Firefox provides an infrastructure that frees you from these tasks, so you can concentrate on your application's functionality. Learn how to use Asynchronous JavaScript + XML (Ajax) to download XML data from a Web server, and discover how you can use Extensible Stylesheet Language Transformations (XSLT) to transform it dynamically into Firefox user-interface elements expressed in XML User Interface Language (XUL). You can apply these techniques to any application that uses XML data sources. |

Convert Atom documents to JSON
Converting an Atom document to JSON might, at first, appear to be a fairly
straightforward task. Atom is, after all, just a bit of XML and XML-to-JSON
conversion tools are widely available. However, the Atom format is more than just
a set of XML elements and attributes. A number of subtle details can make proper
handling of Atom difficult. This article describes those issues and demonstrates a
mechanism implemented by the Apache Abdera project to convert Atom documents into
JSON and produces a result that is readable, usable, and complete. |

Display Google Calendar events on your PHP Web site with XPath
Google Calendar and other online calendaring applications provide simple
centralized systems where online communities can maintain event calendars and
community members can get information about upcoming events. But many organizations
prefer to display event calendars on their community portals, forums, or blogs. They
often copy event calendar information from online calendaring applications
onto their Web sites, reducing the effectiveness of centrally managing events
online. Google Calendar provides an integration application program interface (API)
that provides a good solution to this problem. Find out how to use
XPath to extract and display Google Calendar data on your PHP Web site. |
