Parsing XML Documents

• To evaluate an XPath expression in Java, create an XPath object

  XPathFactory xpfactory = XPathFactory.newInstance();
  XPath path = xpfactory.newXPath();

• Then call the evaluate method

  String result = path.evaluate(expression, doc)

  • expression is an XPath expression
  • doc is the Document object that represents the XML document
     
• For example,

  String result = path.evaluate("/items/item[2]/product/price", doc)

  sets result to the string "19.95".
