Charles F. Goldfarb
When it comes to XML processing, Python is in a league of its own.
If you're doing XML development without Python, you're wasting time! Python offers outstanding productivity especially in the areas that matter most to XML developers, such as XML parsing, DOM/SAX implementations, string processing, and Internet APIs.
And now there's Pyxie the new open source library that makes Python XML processing even easier and more powerful. In XML Processing with Python, top XML developer Sean McGrath delivers the hands-on explanations and examples you need to get results with Python and Pyxie fast even if you've never used them before!
- Install Python and the Pyxie XML package
- Learn the fundamentals of Python: control structures, classes, nested lists, dictionaries, and regular rexpresions
- Process XML with regular expression-driven, event-driven, and tree-driven techniques
- Understand Python's support for DOM and SAX APIs
- Explore the power of Python/XML through worked examples of GUI development, database integration, and an XML query-by-example implementation.
Elegant, easy, powerful and fun, Python helps you build world-class XML applications in less time than you ever imagined. If you know XML, one book has all the techniques, code, and tools you'll need to process it: XML Processing with Python.CD-ROM INCLUDED

This review is from: XML Processing with Python (with CD-ROM) (Paperback)The book spends a lot of time on Python advocacy and tutorial,which is a good thing, but not why I bought it. Turns out the targetaudience of this book is: programmers comfortable with mark-uplanguages in a general sense who haven't programmed in Python before,but are curious. If you already are a python user looking to find outwhat all these acronymns like XML, DTD, XML SCHEMA, XSL, etc. are,you'll find yourself skipping much of the book and coming awaydisappointed. It spends far more time teaching Python than discussingXML's makeup. If you are a power python user looking for XMLprocessing under the hood, it definitely isn't for you.
This bookintroduces pyxie, an XML processing library, along with the basics ofSAX (Simple Api for XML) and DOM (Document Object Model) XMLprocessing techniques in a fairly concise fashion. Armed with aminimal degree of comfort with mark-up languages like HTML or XML, aprogrammer ready to start processing some actual XML files for thefirst time will... Read more

The author struggled to fill this book,
This review is from: XML Processing with Python (with CD-ROM) (Paperback)The first 250 pages of this book are an introduction to Python and XML. 20 of those are screen shots of the Microsoft installer of Python. Every example begins with type <filename> to fill more space. I think he got the choice of typeface from Curious George Rides a Bike (it allows for 25 lines per page). This should have been a 100 page book with no CD since the code on the CD is all outdated.
There are probably 10 or 15 useful pages in this book for someone who knows anything about Python and XML. I was looking for examples about applying style sheets, parsing examples with database connectivity... anything. All the examples he uses can easily be found on the web in a more concise and clear format.

This review is from: XML Processing with Python (with CD-ROM) (Paperback)Very little coverage of processing XML documents using Python - plenty of discussion of Python generally, how to use C language utilities to parse XML, how to use awk to modify the output of the C language tools, etc. The book uses a large typeface and includes examples for both Linux and Windows NT screen input/output (which turn out to be nearly identical), so there's not nearly as much content as you might imagine from the page count. I'm relatively new to XML and Python and I spotted two errors in the examples within the first 100 pages. There are two appendices which sound like they're supposed to explain Python to Java and Perl programmers but turn out to be feature comparisons. That's great fodder for flamewars about language superiority, but not a big help for people with experience in other languages seeking a Python jump-start. People who shell out $() for a book on XML and Python don't need a sales pitch about why XML and Python are good choices.
I think this book could... Read more

XML is everywhere on the Web these days. Structured data of all shapes and sizes such as financial transactions, news feeds, health care records, even HTML is metamorphosing into XML. There is just no getting away from it!
I'm glad actually. The fact that XML is everywhere is a fundamentally good thing in my opinion.
Why? Well, thanks to XML, the Web is in transition from an enormous repository of display-oriented, unstructured, low-level data (HTML) into a repository of structured, heterogenous, content-oriented information (XML). This new, improved World Wide Web, housed on a bedrock of XML, presents programmers with awesome opportunities for innovative software development.
This suits me just fine because software development is what I like to do--even more than writing books about software development.
How to choose?
Well, choosing a programming language is an inexact science at best and is influenced by many factors that are technical, commercial, emotional, futuristic and political in nature. Even serendipity has a role to play.
For my part, standing here (actually sitting here) at the start of the 21st century, I can safely say, without fear of contradiction, that no programming language I know comes close to Python for XML processing.
"Strong words," you may say, but then again, I am only speaking about the languages I know, not the ones I don't.
Enough said! We are not here to engage in programming language warsthat is what Usenet is for. Suffice it to say that Python is a solidly engineered, general-purpose programming language with a natural affinity for text processing in general and XML processing in particular. Mix XML and Python together and you have an explosive cocktail of information representation and information processing power.
In my opinion . . .1.1 - Purpose of This Book
This book has essentially one purpose: To give you all the information, explanations, working examples, and software packages (on the accompanying CD-ROM) you need to start writing XML-processing applications in Python fast.
This book will not slow you down with intricate technical details of either Python or XML. That is not to say that these things are not important! They are very important, but they are not discussed in this book. The reason for this omission is that I believe a pragmatic treatment of a subject such as Python/XML is the best way to become productive quickly. I believe that comprehensive coverage of the details too early on in the exploration of a topic like this just gets in the way. So, in this book, comprehensive coverage takes second place to working examples of real-world Python/XML programming. I will provide plenty of pointers to more detailed information for those of you who wish to dig deeper.1.2 - The Pyxie Open Source Project
This book heralds the beginning of the Pyxie projectan Open Source software development initiative aimed at fully developing Python's potential as an XML-processing platform.
By the time you read this, the Pyxie project will have been launched at

Get involved!1.3 - Prerequisites
This book assumes that you have a high-level understanding of the ideas and syntax of XML. In particular, it would be helpful if you know the following:
- What an element is
- What start-tags and end-tags look like
- What the term "well formed XML" means
- What a DTD (Document Type Definition) is for
If you feel the need to brush up your XML, you might like to read my book XML by Example: Building eCommerce Applications available in this series.
If your programming background is minimal, fear not! Python is a ridiculously easy programming language to learn. Indeed, it makes an excellent first programming language for those approaching the discipline afresh.
If you are a seasoned programmer in one or more languages, I believe you will be pleasantly surprised at how easy, natural, and (okay, I'll say it) beautiful Python is.1.4 - How to Read This Book
This book is intended to be read from start to finish. One of the techniques I have used to avoid long tracts of narrative about Python language features or support libraries is that I explain them as they pop up in the course of writing real programs.
As a consequence, skipping material might lead to gaps in the presentation of Python features. Even if you are very familiar with the subject matter in a section of the book, please give it a high-level scan to ensure that you pick up on any Python nuggets buried inside.
If your background is Java, you might like to read Appendix A before continuing. It introduces Python from a Java programming language perspective. Similarly, you might like to read Appendix B at this point if your background is in the Perl programming language.1.5 - A Note about Platforms
My day-to-day programming environment is a mixture of Windows NT 4.0 and Red Hat Linux 6.0. These are the two platforms that the software presented in this book has been developed and tested on.
Although the book focuses on Windows NT and Linux, the Python programs in the book and in the CD-ROM's root directory should run just fine on any Win32 or Unix platform. There will obviously be the usual assortment of differences to do with default installation directories, differing shells, and so on. I have not attempted to cover all the eventualities in this book. To do so would make it twice as long and ten times more tedious to read.1.7 - And Finally ...
I am a programmer who learns best by example. If this is a reasonable description of how you learn best, you are in the right place.
If you have read this far, you will have surmised that this book is going to take a no-nonsense, snappy, and purposeful approach to XML processing with Python.Ready? Let's go to work ...
