Developers and system administrators alike are uncovering the true power of XML, the Extensible Markup Language that enables data to be sent over the Internet from one computer platform to another or one application to another and retain its original format. Flexible enough to be customized for applications as diverse as web sites, electronic data interchange, voice mail systems, wireless devices, web services, and more, XML is quickly becoming ubiquitous. XML Hacks is a roll-up-your-sleeves guide that distills years of ingenious XML hacking into a complete set of practical tips, tricks, and tools for web developers, system administrators, and programmers who want to go far beyond basic tutorials to leverage the untapped power of XML. With plenty of useful real-world projects that illustrate how to define, read, create, and manipulate XML documents, XML Hacks shows readers how to put XML's power to work on the Internet and within productivity applications. Each Hack in this book can be read easily in a few minutes, saving programmers and administrators countless hours of searching for the right answer. And this is an O'Reilly Hacks book, so it's not just practical, imminently useful, and time-saving. It's also fun. From Anatomy of an XML Document to Exploring SOAP Messages XML Hacks shows you how to save time and accomplish more with fewer resources. If you want much more than the average XML user--to explore and experiment, do things you didn't know you could do with XML, discover clever shortcuts, and show off just a little--this invaluable book is a must-have.

Do [Task] with [Other Object] - 2004-10-02
Reviewer Rating:
Nothing irritates me as much as the industries gratuitous use of the word "hack". I won't say more on this topic other than to advise you that any time you see the word "hack" in this book, substitute it for "tip", "task", or "how to". Once that is understood, this title takes on a whole new feel and its usefulness is made clearer.

Anyone not already familiar with XML, its creation and use, should probably not pick up this book. However, if you are using XML documents a lot, the chances are that this book will yield a resolution method for most of the XML file transformation, modification or parsing need you may have. This method, however, typically requires the use of a third party utility, application, or script (a great many of the tips are titled "Do [something] using [something else]"). A quick flip through the table of contents reveals at least 35 different utilities required to the complete the associated tasks - which is OK if you don't mind incorporating "black box" solutions into your environment. There are also many "see this book" notations within this title as well, so if you find a solution to a need, but require more than what the tip tells you, you may need to make additional purchases.

Overall, a good read for anyone that already knows and makes heavy use of XML; you're sure to walk away with something new.

Great Overview of XML - 2005-12-10
Reviewer Rating:
As a Perl programmer, my first instinct when given some XML to process is to grab the appropriate Perl module (probably XML::XPath or XML::LibXML) and use that to do whatever I need to. Although that usually gets the job done, reading this book opened my eyes to a number of other XML processing tools that will sometimes be more useful than a Perl program. Actually Perl doesn't get mentioned at all in the index, whereas Java gets half a column of entries.

A lot of the book isn't aimed at the kind of person who is comfortable firing up an editor writing a program. Many of the hacks introduce ready-made applications that handle a number of different XML tasks. For example there are applications that, given an XML document, will take a first pass at creating an XML Schema or DTD for the document. This is something that would be an interesting project to write for yourself, but if you just need the schema it's nice to know that someone else has already written the application for you.

One of the most interesting chapters for me was the one about editing XML. My usual tool for that is xml-mode in Xemacs but the book introduced me to a number of other possibilities. The one that particularly caught my eye was nXML for Emacs. Unfortunately it's not currently compatible with Xemacs, so I need to try out some of the other editors that are discussed.

Like all of O'Reilly's Hacks books, this book is aimed at a very wide audience. Some of the tools are Open Source and some of them are commercial. Some of them run on only one platform and some of them will run anywhere. That has the potential to be a little frustrating when you find a tool that looks really useful, only to find out that it only runs on Windows. Fortunately the authors are aware of this problem and make a real effort to present tools that run on as wide a range of platforms as possible. If one hack presents a tool that only runs on Windows then you can be sure that the next hack has a similar tool that runs somewhere else.

The audience is diverse along other dimensions too. There are hacks aimed at people who will just want to save a Word document in DocBook format (hint: use OpenOffice) and at the other end of the spectrum there are hacks aimed at people who want to create SOAP services. There are hacks aimed at all levels of producing and using XML.

It's an inevitable consequence of this type of book that not everyone is going to find all of it useful. But the authors are obviously experts in their field and they explain themselves very clearly. I thought I knew a lot about processing XML but I discovered a lot of new and interesting things from this book. If you want a good overview of the various ways that XML can be useful to you, then this book would be a very good start.

100 Cool Hints and Tips - 2004-09-24
Reviewer Rating:
If you've ever tried to go to a web page automatically and then parse the information by examining the string you got back, you can appreciate XML. While not perfect XML is probably the most practical option for packaging data that can be read by both humans and computers.

As with the other O'Reilly Hacks books, this one contains 100 hints, tips and suggestions on on how to get more out of XML.

I find that whenever I read one of their Hacks books I pick up something useful that just happens to fit the problem I'm working on at the moment. This one was no exception. Great idea! Great Books.

helpful supplement - 2004-11-25

I'm familiar with XML and have found this book to be helpful. Not a book to learn XML, it is a place to pick up new information that can help to complete a toolbox already in the making. There were some hints to bridge gaps between what I want to do and what I know how to do. I plan to have it nearby to make my work easier and faster.
