javax.xml.parsers
public abstract class DocumentBuilder extends Object
An instance of this class can be obtained from the
DocumentBuilderFactory.newDocumentBuilder
method. Once
an instance of this class is obtained, XML can be parsed from a
variety of input sources. These input sources are InputStreams,
Files, URLs, and SAX InputSources.
Note that this class reuses several classes from the SAX API. This
does not require that the implementor of the underlying DOM
implementation use a SAX parser to parse XML document into a
Document
. It merely requires that the implementation
communicate with the application using these existing APIs.
An implementation of DocumentBuilder
is NOT
guaranteed to behave as per the specification if it is used concurrently by
two or more threads. It is recommended to have one instance of the
DocumentBuilder
per thread or it is upto the application to
make sure about the use of DocumentBuilder
from more than one
thread.
Since: JAXP 1.0
Version: 1.0

abstract Document | parse(InputSource is)
Parse the content of the given input source as an XML document
and return a new DOM Document object.
|
abstract void | setEntityResolver(EntityResolver er)
Specify the EntityResolver to be used to resolve
entities present in the XML document to be parsed. |
abstract void | setErrorHandler(ErrorHandler eh)
Specify the ErrorHandler to be used to report
errors present in the XML document to be parsed. |
Returns: A new instance of a DOMImplementation
