This article reviews RSS 2.0, looks at new RSS developments, and jump-starts your understanding of this important format.
The Java XPath API: Querying XML from Java programs
XPath expressions are much easier to write than detailed Document Object Model (DOM) navigation code. When you need to extract information from an XML document, the quickest and simplest way is to embed an XPath expression inside your Java™ program. Java 5 introduces the javax.xml.xpath package, an XML object-model independent library for querying documents with XPath.

XML for PHP developers, Part 1: The 15-minute PHP-with-XML starter: Learn how PHP5 has vastly improved how you work with XML in PHP
This first article of a three-part series introduces PHP5's XML implementation and helps those relatively new to using XML with PHP to read, parse, and manipulate, and write a short and uncomplicated XML file using the DOM and SimpleXML in a PHP environment.
Use the YouTube API with PHP: Process and integrate data from YouTube into your PHP application with PHP's SimpleXML extension
The YouTube video sharing site allows Web application developers to access public content through its REST-based developer API. The SimpleXML extension in PHP is ideal for processing the XML feeds generated by this API and using them to build customized PHP applications. This article introduces the YouTube Data API, demonstrates how you can use it to browse user-generated video content; access video metadata, comments and responses; and perform keyword searches.
- The Java XML Validation API: Check your documents for conformance to schemas
Validation reports whether a document adheres to the rules specified by the schema. Different parsers and tools support different schema languages such as DTDs, the W3C XML Schema Language, RELAX NG, and Schematron. Java 5™ adds a uniform validation Application Programming Interface (API) that can compare documents to schemas written in these and other languages. Learn about this XML validation API
Tip: Convert Excel data to XML: Extract data from the popular spreadsheet program
Believe it or not, not every document is originally written in XML. In this tip, Benoit Marchal explains how to unlock data from Excel files to process them in XML, and examines the pros and cons of different solutions.
A simple SOAP client: A general-purpose Java SOAP client
This article describes a simple, general purpose SOAP client in Java that uses no specialized SOAP libraries. Instead of creating the SOAP request XML document for you under the hood, this client lets you create your own request with any XML editor (or text editor). Instead of merely giving you the remote method's return values, the client shows you the actual SOAP response XML document. The short Java program shows exactly what SOAP is all about: opening up an HTTP connection, sending the appropriate XML to invoke a remote method, and then reading the XML response returned by the server.
