Filing financial statements in XBRL: How-to, lessons learned, and best
practices
In the past few years, eXtensible Business Reporting Language (XBRL)
has emerged to meet increased regulatory and transparency requirements for
financial reporting. The global connectivity of the Internet has encouraged
the rapid development of XBRL standards. Effective December 15, 2008, the US
Securities and Exchange Commission (SEC) will require companies with more than $5
billion in market capitalization to file their financial statements in XBRL.
Over the following two years, all publicly traded companies in the US will
be required to file using XBRL. In this article, learn the fundamentals of
XBRL, the steps in the filing process, and lessons from an actual filing with
the SEC.

Create a framework to support XSLT transformation pipelines
Explore the creation of a framework, called Butterfly, that runs in PHP 5 and
facilitates the applications of chains of XSLT stylesheets to XML source documents.
This provides transparent caching of the transformed results. Inspired by the Java(TM)-based Apache Cocoon project, so named because it houses and manages the transformation of data from one form to another (turning caterpillars into butterflies), this much lighter-weight framework is named Butterfly. With the Butterfly framework, you can set up an XML configuration file to define chains of stylesheet transformations, and then instantiate Butterfly objects that can each produce the result of an XSLT transformation chain. This article will also look at the nature of framework design in general as it sketches out this framework in particular.

Thinking XML: Enrich Schema definitions with SKOS
The things in schemata (people, places and things) are inextricably tied to how people describe them, and this is the key to alignment of business with technology. One of the most important things an XML schema designer can do is express this connection clearly. SKOS, a language well known as a component of DITA, is a very useful means for such expression. Learn how to enrich schema definitions with SKOS definitions.

Advancing with XQuery: Develop application idioms
The XQuery specification is well over a year old now. A surfeit of solid
implementations combined with (if developer chatter is anything to go by) marked new
interest, seems to indicate that XQuery is finally experiencing higher adoption rates.
Possibly this is due to developers starting to figure out how to utilize XQuery within
a rich mixture of XML technologies (such as XML databases. XSLT, XML Schema). Learn how to use XQuery beyond its original role as an XML query language and apply it toward the development of middleware and Web applications.

Overlay data on maps using XSLT, KML, and the Google Maps API, Part 2: Transform and use the data
In this two-part article series, you'll develop an application for a real
estate brokerage to display all available apartment listings as clickable
Placemarks on Google Maps. In Part 1, you created the first half of the
application that collects the apartment listing information from the user, uses
the Google Geocoder Web service to turn the street address into its geographical
coordinates (longitude and latitude), and stores the coordinates in the database
along with the address information. In Part 2, you will use this data to produce a
KML overlay document and display it in Google Maps and Google Earth. First, you'll use stored procedures to produce XML from MySQL. Then with XSLT and a technique called Muenchian grouping, you'll transform the XML data into a KML document containing the overlay information -- one Placemark for each apartment building. The pop-up balloon for each Placemark displays the available apartment listings in that building. Finally, you'll use the Google Maps API to display the KML overlay in a Google Map embedded within your own Web site.

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.

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.

Build a mobile RSS reader
What good is a mobile computing environment if you can't keep track of your favorite news feeds on the go? Sure, you can use Android's browser to read your favorite Web sites, but it's unlikely the sites are optimized for a screen two inches high. And besides, then you'll miss the opportunity to integrate RSS or other XML data with other mobile applications to make your own mash-ups. This tutorial shows you how to use the Android Developer Tools to read, parse, and display XML data.

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.

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.

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.

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.

Expand the editing capabilities of OpenOffice with XSLT
You might know that you can pull XML data into OpenOffice's spreadsheet program, Calc, but did you know that you can create a filter to make word-processing documents out of data stored as XML? This tutorial shows you how to use OpenOffice's import/export filters to open your XML data as though it's just a plain document. From there, users can edit the document much more naturally and then save it back to its native format. You can also use this feature to easily turn your documents into XML data.

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.
