Create an alerts system using XMPP, SMS, pureXML, and PHP
Thanks to the native XML support that pureXML offers IBM DB2 database developers, you can load XML data directly into your database, freeing up development time to add functionality to your application. Follow along in this tutorial to import an XML file with Euro foreign exchange rates into an IBM DB2 database and use special XQuery and SQL/XML functions to split this XML into separate database rows. You will also create a PHP script that pulls down new rates from the European Central Bank (ECB) Web site each day. Then you will extend the script to send update alerts to a Google Talk user using the XMPP protocol, and to a cell phone by SMS text message using the Clickatell SMS gateway service. Finally, you will create a PHP script that generates a PNG (Portable Network Graphics) graph of this data.

Trace the growth of XML over 10 years
XML was born in 1998 when it became a Worldwide Web Consortium (W3C)
recommendation and the IBM developerWorks Web site was launched the following year. Over those 10 years, the XML zone has hosted over a thousand articles, tutorials, and tips. We've covered technology, tools, standards, products, best practices, predictions, evaluations, and developer experiences, and have supported a variety of forums. A 10-year birthday is a good time to look back at some of the authors who made the XML zone what it is.

Enforce basic document structure with XML constraint checking
The ability to specify, check and act upon constraints is vital to
ensuring the overall quality of healthcare information. The Health Level 7
(HL7) Clinical Document Architecture (CDA), described through XML Schema,
allows the specification of constraints through HL7 Templates, which can be
implemented in Schematron. Schematron can be applied through XSLT. This article illustrates software and
hardware solutions for constraint checking in the HL7 CDA. The two
solutions are demonstrated in an SOA that
includes both successful and failing XML Schema and Schematron constraint
checks. The article evaluates the application of constraints in the HL7 CDA
and identifies some categories of constraints that require further investigation.
The outcome of this evaluation shows that the ability to specify, check, and act
upon constraints through Schematron complements XML Schema processing. The two
constraint approaches are very useful and practical, and should therefore be
pursued further.

Creating an Atom feed in PHP
Atom is an Extensible Markup Language (XML) specification that identifies information contained in a Web site. Using Atom, Web developers produce feeds that enable other Web developers (or consumers who use feed readers) to quickly locate and view information of interest on a remote site. Think of it as a Web site's index, available to anyone who wants it. Using PHP, a popular language of choice for most host providers, a Web developer can easily produce an Atom feed that can then be made available to the various feed readers and other Web developers. The ultimate result is a state-of-the-art information solution that enables the Web content to reach a much wider audience.

Build Wikipedia query forms with semantic technology
By providing open access to increasing amounts of Linked Data, public SPARQL endpoints boost the growth of the Semantic Web by providing great data for you to use in your applications. As with many other data-driven Web sites out there, you can create a Web page by sending a query to these endpoints and then wrapping the results in HTML tags; the big difference for SPARQL endpoints is the public availability of this new data for your applications. With simple CGI scripting, get data from two different SPARQL endpoints to build applications that answer your user's questions about actors shared between two directors and which musicians have released which albums.

Integration between XML Forms Generator and Data Studio, Part 1: Get started with the integration by creating an application
The XML Forms Generator (XFG) provides a jump-start for form development. It can
quickly and automatically produce valid and functional forms containing XForms markup
embedded within an XHTML document. The input to form generation can be an XML data
instance with or without a backing XML Schema, or a WSDL document. Data Web Services,
which is based on SQL scripts and Store Procedures, is a database related application
of traditional Web Services. IBM Data Studio is a client tool for generating Data Web Services visually with the help of direct connection to database.
The integration between XFG and Data Studio can enable to generate XForms/XHTMLs from Data
Web Services generated by Data Studio. This integration provides advantages such as joining the development of UI pages and Data access seamlessly, reducing the workload of UI development from Data Web Services, visualizing the pureXML UI development with full-support of validation, etc.

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.

Create a Java applet to download information in remote Web services
Start with a Java applet and build a server-based
proxy system that uses your browser to access an arbitrary Web service. You'll use
JavaScript code to access applet-based information and call a servlet, which retrieves
the remote information. Thus, you bypass the same-server restrictions on what an
applet can and cannot do.

Overlay data on maps using XSLT, KML, and the Google Maps API, Part 1: Tap into the Google Geocoder Web service
Explore the Google Geocoder Web service that takes a street address and
returns data about that address including its longitude and latitude. In this two-part article series, you will combine it with the Google Maps API and XSLT to create data overlays for display in Google Maps and Google Earth. You will create an example application for a real-estate brokerage that lets a broker enter listings for apartments through an HTML form, uses Google's Geocoder Web service to translate those addresses into longitudes and latitude, and then creates KML overlays from the database of apartment listings. In Part 1, you build the first half of the application to collect 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 those coordinates in the database along with the address information.

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.

Services-based enterprise integration patterns made easy, Part 3: Web services and registry
Part 1 and Part 2 of this series covered the basic concepts necessary to
develop services-based integration patterns. This article, the third in the series,
and the upcoming Part 4 further develop these ideas so the services-based
integration patterns become full-blown services-based patterns. This article in
particular deals with the components that are together commonly referred to as Web
services, which were originally designed for services that can be accessed over the
Internet. You'll also see that many of the Web services components can be used with
services that don't use the Internet and that only require a network connection.

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.

(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.

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.

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.
