#XPATH FOR TEXT WITH BR HOW TO#

In this chapter, we'll see the XPath expression in details covering common types of Nodes, XPath defines and handles. In this example, we've created a sample XML document, students.xml and its stylesheet document students.xsl which uses the XPath expressions under select attribute of various XSL tags to get the values of roll no, firstname, lastname, nickname and marks of each student node. Selects all student elements no matter where they are in the document Selects the parent of the current attributesĮxample − Selects all nodes with the name 'student'Įxample − Selects all student elements that are children of class Selection starts from the current node that match the selection Select all nodes with the given name 'nodename' XPath uses a path expression to select node or a list of nodes from an XML document.įollowing is the list of useful paths and expression to select any node/ list of nodes from an XML document.

XPath specification specifies seven types of nodes which can be the output of execution of the XPath expression. These patterns are used by XSLT to perform transformations or by XPointer for addressing purpose. XPath is core component of XSLT standard.Īn XPath expression generally defines a pattern in order to select a set of nodes.One should keep the following points in mind, while working with XPath −

W3C recommendation − XPath is an official recommendation of World Wide Web Consortium (W3C). Major part of XSLT − XPath is one of the major elements in XSLT standard and is must have knowledge in order to work with XSLT documents. Standard Functions − XPath provides a rich library of standard functions for manipulation of string values, numeric values, date and time comparison, node and QName manipulation, sequence manipulation, Boolean values etc. Path Expressions − XPath provides powerful path expressions select nodes or list of nodes in XML documents. Structure Definitions − XPath defines the parts of an XML document like element, attribute, text, namespace, processing-instruction, comment, and document nodes XPath provides various types of expressions which can be used to enquire relevant information from the XML document. It is used to traverse elements and attributes of an XML document. It defines a language to find information in an XML file. XPath is an official recommendation of the World Wide Web Consortium (W3C). XSLT − used to transform XML documents into various other types of document. An XSL document specifies how a browser should render an XML document. In order to understand and style an XML document, World Wide Web Consortium (W3C) developed XSL which can act as an XML-based Stylesheet Language. But in case of XML documents, tags are not predefined.

The browser knows how to add style to them and display them using CSS styles. In case of HTML documents, tags are predefined such as table, div, span, etc. Before learning XPath, we should first understand XSL which stands for Extensible Stylesheet Language.
