  • Xpath Overview
    XXPPAATTHH OOVVEERRVVIIEEWW http://www.tutorialspoint.com/xpath/xpath_overview.htm Copyright © tutorialspoint.com XSL Before learning XPath, we should first understand XSL which stands for EXtensible Stylesheet Langauge. It is similar to XML as CSS is to HTML. Need for XSL In case of HTML document, tags are predefined such as table, div, span and browser knows how to add style to them and display them using CSS styles. But in case of XML document, tags are not predefined. In order to understand and style an XML document, World Wide Web Consortium W3C developed XSL which can act as XML based Stylesheet Language. An XSL document specifies how a browser should render an XML document. Following are the main parts of XSL. XSLT - used to transform XML document into various other types of document. XPath - used to navigate XML document. XSL-FO - used to format XML document. What is XPath The XPath is an official recommendation of the World Wide Web Consortium W3C. It defines a language to find information in an XML file. It is used to traverse elements and attributes of an XML document. XPath provides various types of expressions which can be used to enquire relevant information from the XML document. Structure Definations - XPath defines the parts of an XML document like element, attribute, text, namespace, processing-instruction, comment, and document nodes Path Expressions XPath provides powerful path expressions select nodes or list of nodes in XML documents. Standard FunctionsXPath 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.

  • Xpath Is a Syntax for Defining Parts of an XML Document. Xpath Uses Path Expressions to Navigate in XML Documents
    XML PROGRAMMING: SUB CODE- 24662 QPCODE: -780 PART-A (Each question carries 1 marks, Answer any FIFTEEN(15) questions) 1.Mention any two part of XML tree structure. Root node Leaf node 2. Write any two use of XPath. (Any Two) XPath is a syntax for defining parts of an XML document. XPath uses path expressions to navigate in XML documents. XPath contains a library of standard functions. XPath is a major element in XSLT and in XQuery. XPath is a W3C recommendation. 3. Define WML. Wireless markup language (WML) is a markup language for wireless devices that adhere to Wireless Application Protocol (WAP) and have limited processing capability. 4.What is an absolute location path? Location path specifies the location of node in XML document. This path can be absolute or relative. If location path starts with root node or with '/' then it is an absolute path. Following are few of the example locating the elements using absolute path. 5.Write the limitation of schema language. Poor support for xml namespace Poor data typing Limited content model description It supports only the text string data type. Limited possibilities to express the cardinality for elements. 6.Mention any two declaration that can be used in DTDs. (Any Two) <!ELEMENT letter (date, address, salutation, body, closing, signature)> Element – letter Child Elements - date, address, salutation, body,closing,signature <!ELEMENT Name (#PCDATA)> #PCDATA – parsed character data - Data contains only text 1 <!ELEMENT Street (#CDATA)> #CDATA – Character Data - Data may contain text, numbers and other character. <!ELEMENT br EMPTY> EMPTY – It has no content.
