This book is a basic introduction to how Perl handles XML and people looking for a in depth book on Perl and XML will be dissapointed. That does not mean that the book is not good, because it is. It has easy explanations and it covers a wide range of different Perl XML modules and gives examples on how to use them, but since it is only a thin book it does not cover as much as one might like. If you are a Perl programmer looking for a book to give you a quick overview of what is available then this book is for you. But if you are looking for larger examples and in depth explanations this is problably not the book for you.
