ARTICLES & TUTORIALS FOR XML DEVELOPMENT: XML NameSpaces Tutorials such as Schemas, Infosets, DTDs, Duplicate Element Types and Attributes

XML Namespaces - XML Namespaces provide a method to avoid element name conflicts.

XML Namespaces Explained - There are really two fundamental needs for namespaces…

XML and Namespaces, a brief introduction - A brief introduction on xml namespaces to let you know about it. It is very comprehensive tutorial on namespaces…

Extensible Markup Language (XML) - Extensible Markup Language (XML) is a simple, very flexible text format derived from SGML (ISO 8879). Originally designed to meet the challenges of large-scale electronic publishing, XML is also playing an increasingly important role in the exchange of a wide variety of data on the Web and elsewhere.

Understanding XML Namespaces - Introduction - This article is geared towards Visual Basic developers. If your work involves HTML more than programming, there’s an excellent namespace tutorial that speaks to your needs.

Using W3C XML Schema - The W3C XML Schema Definition Language is an XML language for describing and constraining the content of XML documents. W3C XML Schema is a W3C Recommendation..

Namespace Tutorial - This Tutorial will guide you how to know about xml namespaces…

Back to Basics: XML In .NET - One of the most exciting recent advances in computing has been XML. Designed as a stricter and simpler document format than SGML, XML is now used everywhere to produce cross-platform interoperable file formats.

XML Namespaces Support in Python Tools, Part 1 - I have covered a lot of tools for processing XML in Python. In general I have deferred discussion of each tool's handling of XML namespaces in order to stick to the basics in the individual treatments. In this article I start to examine the support for XML namespaces in these packages, with a look at SAX and DOM from the standard Python library.

XML Namespaces Support in Python Tools, Part Two - In the last article I discussed namespace handling in Python 2.3's SAX and minidom libraries. As I pointed out there are a lot of pitfalls and oddities involved with processing namespaces, and I will continue to give the same treatment to the namespace support in third party Python libraries. In this article I shall focus on the various libraries packaged in 4Suite. If you need background on 4Suite, see my earlier article "A Tour of 4Suite ". I did briefly cover how to express namespaces for use in 4XPath in that article, but in this one I will explore different angles on the topic.

XML Namespaces Support in Python Tools, Part Three - In the last two articles I've discussed namespace handling in Python 2.3's SAX and minidom libraries and in 4Suite. In this article I focus on ElementTree, libxml/Python and PyRXPU. I recommend reading or reviewing those articles first, as well as the earlier articles in this namespace series (part 1 and part 2).

XML Versus the Infoset - In my prior columns I've examined specific protocols and pieces of the web services infrastructure, including WSDL, SOAP attachments, and so on. I've picked them up, looked all around, and tried to figure out when and how to use them. More importantly, I've tried to uncover some of the dark corners and trade-offs associated with these technologies. While there's certainly room for disagreement about some of the suggestions, I think it's clear that there's a technical basis behind all the commentary.

XML Schema - XML Schemas express shared vocabularies and allow machines to carry out rules made by people. They provide a means for defining the structure, content and semantics of XML documents. in more detail. XML Schema was approved as a W3C Recommendation on 2 May 2001; see reference list for pointers.

Namespaces - I'll try my best to explain namespaces. If anyone has a more concise and clearer explanation, please email it to me!

Namespace Myths Exploded - The XML namespaces recommendation is tantalizingly vague about, or omits altogether, a number of apparently important points.

XML Namespaces - The XML Namespaces Recommendation seems to be causing a great deal of confusion. This note attempts an alternative explanation of the mechanism described in the Recommendation which I hope will be less confusing.

XML Namespaces FAQ - The XML namespaces recommendation defines a way to distinguish between duplicate element type and attribute names. Such duplication might occur, for example, in an XSLT stylesheet or in a document that contains element types and attributes from two different DTDs.....

XML, Part 3: XSLT Stylesheets - In my previous two Tutorial, XML, Part 1: XML and Namespaces, and XML, Part 2: XML Schemas, I covered basic and intermediate topics regarding XML documents, a strict standard for loose data and graphs. Unlike HTML (though both are decribed using SGML), there is no User Interface (UI) associated with the tags and there is not a set of tags like in HTML, unless you are conforming to a particular schema (see Part 2 for more details)...

Reading and Wtiting XML Documents - In this article you will see how to read and write XML documents in Microsoft .NET using C# language. First I will discuss XML .NET Framework Library namespace and classes in brief. Then we will read and write XML documents. At the end of this article, I will show you how to take advantage of ADO.NET and XML .NET model to read and write XML documents from relational databases and vice versa.

Introduction To XML - To help you evaluate our training, we have made some of the Tutorial for Introduction To XML freely available. Click on any of the linked lesson listings below to preview FREE!

XML - XML Namespaces by Example - Namespaces are a simple and straightforward way to distinguish names used in XML documents, no matter where they come from. However, the concepts are a bit abstract, and this specification has been causing some mental indigestion among those who read it. The best way to understand namespaces, as with many other things on the Web, is by example.

XML - Namespaces in XML Adopted by W3C - The "Namespaces in XML" specification has been formally adopted by the W3C as a recommendation from its members and its director, Tim Berners-Lee, paving the way for vendors to create software that will more easily support the rich markup vocabularies made possible by XML.

XML - Old Ghosts: XML Namespaces - While some of us were enjoying holiday celebrations, XML-DEV was haunted once more by that ghostly question, "what does a Namespace URI resolve to?" This time, however, the community was reluctant to descend into a two thousand message discussion. This article summarizes the promising progress made to date.

XML - Namespace Trouble - This week XML Deviant reports on a Namespace-related debate holding up XML work at the W3C, and the final release of SAX2/Java.

XML - Opening Old Wounds - This week's XML-Deviant explores a namespace debate that has resurfaced on XML-DEV and wonders whether a few rays of sunshine could dry up this and other debates once and for all.

XML - Namespaces and Stylesheet Logic - In last month's "Transforming XML" column, we saw how to control the namespaces that are declared and referenced in your result document. If your stylesheet needs to know details about which namespaces are used in your source document, and to perform tasks based on which namespaces certain elements or attributes belong to, XSLT offers a variety of ways to find out. This month we look at them.

XML - Namespace Nuances - I'm trying to validate an XML file. It uses XML namespaces, but I can't figure out how to express them inside the DTD. Here's a sample XML document..

XML - Schema Scuffles and Namespace Pains - Leigh Dodds, after a well-deserved vacation, will be returning next week. Meanwhile, after the latest bout of XML conferences, I have the pleasure of casting the XML-Deviant's eye over some of May's developments in the XML developer community.

XML - Answering the Namespace Riddle - This tutorial introduces the Resource Directory Description Language (RDDL), which is the result of a recent project conducted by the XML-DEV community. It provides an overview of RDDL's very simple vocabulary and the benefits it can bring to XML

XML - Trickledown Namespaces - Some time ago I read something about namespace declarations which said, "The namespace declaration given for the current element is also valid for all its children and descendants..

XML - Namespaces, Name With Spaces, and Attribute Values - Although the W3 Schema specification uses the namespace prefix xsd:, it looks as though in current practice only xs: is used. Could you please confirm if this is the case and is the reason just that it is shorter?

Introduction to XHTML - DTD stands for Document Type Definition. In XHTML, the page author must specify which DTD the document supports. You can think of the DTD as being the list of XHTML language rules that must be abided by for the document to be considered valid.

XML - XML Namespace Processing in Apache - The Apache 2 filter architecture serves to transform Apache from a mere web server into a powerful application platform. Applications that previously required a dedicated backend, typically Java-based, can now easily be implemented within the web server itself, with very substantial improvements in system performance

5. XML Schemas and Support for Multiple Record Formats in OAI-PMH - OAI-PMH uses XML Schemas to define record formats. You can exchange any metadata you like using OAI-PMH as long as you can encode it as XML and define an XML Schema for it. OAI-PMH mandates the oai_dc schema as a minimum standard for interoperability…

Oracle XML Parser Techniques - This series of Tutorial answers some frequently-asked questions about using the XML Parser for Java v2, part of the XDK for Java. Oracle XML Developer's Kit (XDK) contains XML component libraries and utilities that you can use to XML-enable applications and Web sites

XML - W3C XML Schema Made Simple - It's easy to learn and use W3C XML Schema once you know how to avoid the pitfalls. You should at least learn the following things.

W3 - Namespaces in XML - This document has been reviewed by W3C Members and other interested parties and has been endorsed by the Director as a W3C Recommendation. It is a stable document and may be used as reference material or cited as a normative reference from another document. W3C's role in making the Recommendation is to draw attention to the specification and to promote its widespread deployment. This enhances the functionality and interoperability of the Web.

Understanding XML Namespaces - Namespaces are the source of much confusion in XML, especially for those new to the technology. Most of the questions that I receive from readers, students, and conference attendees are related to namespaces in one way or another. It's actually kind of ironic since the Namespaces in XML Recommendation is one of the shorter XML specifications, coming in at just under 10 pages, excluding appendices. The confusion, however, is related to namespace semantics as opposed to the syntax outlined by the specification. To fully understand XML namespaces, you must know what a namespace is, how namespaces are defined, and how they are used.

Working with Namespaces in XML Schema - Dare Obasanjo discusses various aspects of W3C XML Schema and how they are affected by namespaces. Topics covered include proper usage of the targetNamespace, elementFormDefault and attributeFormDefault attributes, as well as the include, import, and redefine elements within a schema.

MSDN.Microsoft - Understanding Infosets - Covers the most important types of information items and their properties, the mapping between Infoset properties and the serialization format defined by the Extensible Markup Language (XML) 1.0 and Namespaces in XML specifications, and the relationship between the Infoset and XML programming APIs.

XML Tutorial 4: Working with Namespaces and Schemas - How to use XML Spy to generate schema from an XML document and other related topics…

What's in A Name(space)? - XML promises the ability to describe data from all sorts of domains. Once you have an XML vocabulary and a DTD, you can say anything about a domain that the vocabulary and DTD allow. What do you do when your vocabularies overlap?

XML standards - Namespaces in XML - Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat.

XML Namespaces and How They Affect XPath and XSLT - This article explores the ins and outs of XML namespaces and their ramifications on a number of XML technologies that support namespaces. What follows is a shortened version of my first Extreme XML column.

Beginning XML - This book teaches you all you need to know about XML - what it is, how it works, what technologies surround it, and how it can best be used in a variety of situations, from simple data transfer to using XML in your web pages. It builds on the strengths of the first edition, and provides new material to reflect the changes in the XML landscape - notably SOAP and Web Services, and the publication of the XML Schemas Recommendation by the W3C.
