Xpath and Xpointer

This hands-on book fills an essential need for XML developers by dealing with a topic that has been addressed inadequately up until now. Written by an author with a considerable amount of XML experience, Xpath and Xpointer offers practical knowledge on the two languages that underpin XML, XSLT, and Xlink. By referencing parts of documents, both Xpath and Xpointer play a key role in XML processing, allowing developers to manipulate embedded information. This book is packed with examples that demonstrate exactly how to use Xpath in different situations, showing developers a clear path for working with XML documents.
