Questions tagged [jxpath]

JXPath is a Java package that enables extraction of data from hierarchical data structures using XPath notation. JXPath can apply XPath expressions to graphs of objects of all kinds: JavaBeans, Maps, Servlet contexts, DOM etc, including mixtures thereof.

Example:

Address address = (Address)JXPathContext.newContext(vendor).
         getValue("locations[address/zipCode='90210']/address");

This XPath expression is equivalent to the following Java code:

Address address = null;
Iterator it = vendor.getLocations().iterator();
while (it.hasNext()){
    Location location = (Location)it.next();
    String zipCode = location.getAddress().getZipCode();
    if (zipCode.equals("90210")){
      address = location.getAddress();
      break;
    }
}
