Python is an ideal language for manipulating XML, and this new

volume gives you a solid foundation for using these two languages

together. Complete with practical examples that highlight common

application tasks, the book starts with the basics then quickly

progresses to complex topics like transforming XML with XSLT

and querying XML with XPath. It also explores more advanced

subjects, such as SOAP and distributed web services.

Printed in the United States of America.
