This class defines a high-level API to
an underlying DOM parser implementation. Obtain a
DocumentBuilder from a
DocumentBuilderFactory. After obtaining a
DocumentBuilder, you can provide
org.xml.sax.ErrorHandler and
org.xml.sax.EntityResolver objects, if desired.
(These classes are defined by the SAX API but are useful for DOM
parsers as well.) You may also want to call
isNamespaceAware( ), isXIncludeAware(
) and isValidating( ) to ensure that the
parser is configured with the features your application requires.
Finally, use one of the parse( ) methods to read
an XML document from a stream, file, URL, or
org.xml.sax.InputSource object, parse that
document, and convert it into a
org.w3c.dom.Document tree. Note that
DocumentBuilder objects are not typically
threadsafe. In Java 5.0, you can call reset( ) to
restore the parser to its original state for reuse. Another Java 5.0
method, getSchema( ) returns the
Schema object, if any, registered with the
DocumentBuilderFactory that created this parser.
If you want to obtain an empty Document object (so
that you can build the document tree from scratch, for example) call
newDocument( ). Or use
getdOMImplementation( ) to obtain a the
org.w3c.dom.DOMImplementation object of the
underlying DOM implementation from which you can also create an empty
Document.
See the org.w3c.dom package for information on
what you can do with a Document object once you
have used a DocumentBuilder to create it.
