java - JAXP XpathFactory Object model -

What is the object model in XPathFactory ?

Is it important for that?

Does this affect performance of the application?

The device and the claims that the default object model is:

DEFAULT_OBJECT_MODEL_URI = "http://java.sun.com/jaxp/xpath/dom"

Ul>

Object model is selected below:

  string objectModel = "http://java.sun.com/jaxp/xpath/dom"; XPathFactory xpathFactory = XPathFactory.newInstance (objectModel); XPath xpath = xpathFactory.newXPath ();  

JAXP DEFAULT_OBJECT_MODEL_URI provides a default implementation that is w3c DOM. If your classpath has jdom, you can specify that XPathFactory uses the JDOM document object model. View the JAXP XPath example
