This manual is a printed edition of the XPath 2.0 standard from the World Wide Web Consortium (W3C). XPath is an open standard for addressing nodes in XML documents. It allows XML nodes to be referenced by absolute and relative positions, and by complex matches on attributes using numeric, boolean and date expressions. For each copy of this manual sold, the publisher donates 1 USD to support the development of freely-redistributable XML-related software projects.
