Effective XML: 50 Specific Ways To Improve Your XML

Learning the fundamentals of XML might take a programmer a week. Learning how to use XML effectively might take a lifetime. While many books have been written that teach developers how to use the basic syntax of XML, this is the first one that really focuses on how to use XML well. This book is not a tutorial. It is not going to teach you what a tag is or how to write a DTD (Document Type Definition). Instead it's going to tell you when, why, where, and how to use such tools effectively (and equally important when not to use them).Since XML has become a fundamental underpinning of new software systems, it becomes important to ask new questions, not just what XML is, but how does one use it effectively? Which techniques work and which don't? Perhaps most importantly, which techniques appear to work at first but fail to scale as systems are further developed? This book answers these questions. It is not enough to write programs that compile and produce the expected results. It is important to write code that is extensible, legible, and maintainable. XML can be used to produce robust, extensible, maintainable systems.

Pass On This One
I've been using XML for about six years and found this book to repeat the common already understood best practices. I was expecting this book to bring new ideas to light but instead it focused on common design practices already understood within the XML community (i.e. do I make a piece of data an element or a attribute?). To the authors credit he does give very thorough explainations and he knows XML well. I guess more than anything this book didn't match my expectations, however it is a well written and would work for folks new to the XML community.

User review
Excellent resource for both quality control and ideas
I bought this book quite a while ago and I absolutely the format. It's a great resource to just pick up and get great ideas, verify that you are on/off the right track and generally learn how to get to the next level with XML. Highly recommended

How to Effectively Use XML
Elliotte Rusty Harold states in the introduction of Effective XML that the book is neither an introductory book nor an XML tutorial. Rather, it is a distillation of the author's experience using and teaching XML and how to use it effectively. The book does a great job of explaining how to use XML and its related technologies.


The book is divided into four major sections: Syntax, Structure, Semantics, and Implementation. Each of the fifty Items packs a lot of information into a few pages. The Items span topics such as why you should Include an XML Declaration (Item 1), Make Structure Explicit through Markup (Item 11), Program to Standard APIs (Item 31), and Write in Unicode (Item 38). Even the Introduction is valuable because it sets the definitions for XML-related terms used in the rest of the book that the author has found to be used interchangeably or inconsistently.


Item 24, Choose the Right Schema Language for the Job, provides a typical example of the great information contained in Effective XML. This Item discusses the strengths and weaknesses of four schema languages: W3C XML Schema Language, DTDs, RELAX NG, and Schematron. The use of programming languages to handle situations that the schema languages can't handle is also discussed. The Item ends with a set of questions to think about when selecting the schema language to use.


I found the book very readable and like that the information is presented in digestible chunks. Effective XML isn't meant to hype XML but to identify what the actual capabilities of XML and its related technologies are and how best to use them. The book does an outstanding job at this task.


Full disclosure: I received a complimentary copy of the book for review.

I wish the XML Schema working group had a copy per member
This is not a book explaining XML. This is not a book that goes into any depth on XML APIs. It is not a book explaining any one XML format like XSLT, RSS, or XSD.


Instead it is a book on how to work with XML. How to design an XML application to take full advantage of the facilties of XML: schemas, processing instructions, XSL transforms, namespaces. It is all structured to slowly introduce you into the complexities, and deserves to sit up on the bookshelf with Effective C++, Java and Enterprise Java.


If you already know the basics of XML, it is actually quite a good way to learn about some of the more esoteric concepts -from the pragmatic perspective. Too many XML books rant about how wonderful some feature like XML schema's extension stuff is, why XML is the most universal format ever, SOAP and WS-* the best protocol for distributed systems ever, and XQuery everything you need for an XML database.


This book bursts the bubble of hype with rational analysis of what makes sense, and what doesn't. Item 28: Use only what you need, is my favourite: A review of the main XML specs and analysis of what really matters, which comes down to #35, navigate with XPath.


If you are designing an XML schema/system/application, you need this book. If you have to put up with architects telling you about WS-MetadataExchange, WS-Transfer and RDF, you need a copy to roll up and hit them over the head. And, if like me, you are involved in standards bodies that produce XML related things, you need to buy a copy for all the other participants, so that what you produce will actually work.


Remember that XML is a language designed for use by people and machines. The machines have the upper hand. But with this book, and some thinking, you can design XML applications that people can use.

Great gap between book knowledge and effective use,,.
The flexibility of XML can often mean that there's a gap between using XML and using XML effectively. Elliotte Rusty Harold's book Effective XML - 50 Specific Ways to Improve Your XML (Addison Wesley) is an excellent way to move towards the latter condition.

There are obviously a large number of books that will teach you the semantics of writing and using XML. But just because you can create an XML file doesn't mean that you've done it well or effectively. Harold's book provides a bridge to being able to create XML files that will be usable in nearly all situations. The book starts out in the introduction with explanations of terms that are often confused (element vs. tag, text vs. character data vs. markup, etc.). Then there are four parts of the book that include a total of 50 tips that will improve the quality of your XML usage. Some tips are pretty basic, like `Include an XML Declaration`. Others are more complex like `Verify Documents with XML Digital Signatures`. But every one is practical and useful for making sure that your XML is widely useable by all potential applications.


Excellent bridge book to read after you've learned the basics of XML. This is a book that, when taken to heart and used, will cause your coworkers to thank you.
