XML. Tworzenie stron WWW z wykorzystaniem XML, CSS, XHTML oraz XSLT. Niebieski podręcznik
Rob Huddleston
Odpowiedzi na wszystkie Twoje pytania dotyczące XML w jednym miejscu! Do czego potrzebuję formatu XML? Jak zapewnić poprawność plikom XML? Jak przetworzyć plik XML do formatu XHTML? XML znaczy tyle, co "rozszerzalny język znaczników". Prawdopodobnie słowo "rozszerzalny" w tym skrócie jest najważniejsze. Oznacza ono, że jako użytkownik możesz zdefiniować tyle znaczników, ile tylko jest Ci potrzebnych w danym przypadku. XML jest uniwersalnym językiem formalnym, za pomocą którego można reprezentować dane w usystematyzowany, strukturalny sposób. Niezależność od platformy jest niewątpliwie tą cechą, która pozwoliła mu na zdobycie ogromnej popularności -- stał się on wręcz swego rodzaju standardem. W dodatku język ten pozwala na tworzenie stron internetowych przy użyciu XHTML, czyli przedstawienie HTML w postaci XML. Mało? Dzięki zastosowaniu XSLT możesz także przekształcić dowolny dokument XML do postaci XHTML! Dzięki książce "XML. Tworzenie stron WWW z wykorzystaniem XML, CSS, XHTML oraz XSLT. Niebieski podręcznik" poznasz podstawy XML i sposób przetwarzania plików XML za pomocą języka XSLT oraz dowiesz się, jak wybrać dobry edytor, pozwalający na wygodną pracę z dokumentami. W kolejnych rozdziałach zdobędziesz wiedzę na temat sposobów wykorzystania atrybutów i przestrzeni nazw oraz stworzysz swój pierwszy dokument XML. Ponadto nauczysz się definiować strukturę dokumentu za pomocą schematów i zobaczysz, jak łatwo można oceniać poprawność dokumentów XML. Autor książki zaprezentuje Ci również technikę generowania dokumentów XML na podstawie istniejących danych, między innymi w programach Access i Excel, oraz technikę przekształcania plików XML do formatu XHTML za pomocą języka XSLT. Jeżeli interesuje Cię format XML i formaty pokrewne, trzymasz w ręku książkę, której poszukiwania zajęły Ci tak dużo czasu!

When Alex told me he was about to write a Yii cookbook about a year ago, I was wondering how original it would be, considering the fact that there was already an online user-contributed cookbook (aka. Yii wiki). It turned out Alex produced a book that is not only full of wisdom about how to use Yii effectively, but also presented in such a systematic way that it can be taken as an essential companion book to the definitive guide to Yii. In fact, Alex has successfully intrigued the interest of every member in the Yii developer team when he asked for review and comments on his newly finished book chapters.As the founder and the lead developer of the Yii framework, I feel this book is a must-read for every Yii programmer. While this book does not describe directly the rules set by Yii, it shows how to program with Yii from a practical perspective. People who are driven by tight project schedules will find this book very handy as it gives ready-to-use solutions to many problems they may face in their projects; people who are already familiar with Yii will also find this book very informative as most problem solutions given in the book can be considered as officially recommended because they have undergone thorough review of every Yii developer team member. Alex, through this book and his active participation in the Yii project, proved himself to be a great programmer as well as a good writer.Qiang XueLead developer of the Yii frameworkYii framework is a rapidly growing PHP5 MVC framework often referred to as Rails for PHP. It has become a solid base for many exciting web applications such as Stay.com and Russia Today's meetfriends.rt.com and can be a good base for your developments.
