You can use XPathExpression from javax.xml.xpath package to create and execute XPATH expression in Java. Java API provides javax.xml.xpath package, which contains classes like Xpath , XpathFactory to work with XPATH and XML documents. By the way this is third article on Xpath, In last couple of tutorials e.g. XPATH examples to select values using attributes and my XPATH notes for Java programmer , we have seen basics of Xpath expression from XML and Java point of view. Anyone who has work with XML technologies in Java knows importance of XPATH, it is one the most useful technology to retrieve selected data from XML files. XPATH is like SQL which is used to retrieve data from relational database. Many back-office and middle-office Java application which transfers data in form of XML documents makes extensive use of XPATH expression to retrieve value for printing or for decision making.

Some time back I have shared my XPATH notes for Java programmer and this example shows true power of XPATH as how convenient its to made selective decision. For those who are completely new in XML and XPATH, XPATH is great xml tool which allows you to query XML document and select or retrieve selective data much like SQL but if you are new to XPATH or haven't had much experience with XML tool and technology than you wi...
