DocumentBuilder

class
DocumentBuilder
extends Object
java.lang.Object | |
↳ | javax.xml.parsers.DocumentBuilder |
Defines the API to obtain DOM Document instances from an XML
document. Using this class, an application programmer can obtain a
Document
from XML.
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.

UnsupportedOperationException |
For backward compatibility, when implementations for earlier versions of JAXP is used, this exception will be thrown. |
isNamespaceAware
public abstract boolean isNamespaceAware ()
Indicates whether or not this parser is configured to understand namespaces.
Returns | |
---|---|
boolean |
true if this parser is configured to understand namespaces; false otherwise. |
isValidating
public abstract boolean isValidating ()
Indicates whether or not this parser is configured to validate XML documents.
Returns | |
---|---|
boolean |
true if this parser is configured to validate XML documents; false otherwise. |
isXIncludeAware
public boolean isXIncludeAware ()
Get the XInclude processing mode for this parser.
Returns | |
---|---|
boolean |
the return value of
the DocumentBuilderFactory#isXIncludeAware()
when this parser was created from factory. |
Throws | |
---|---|
UnsupportedOperationException |
For backward compatibility, when implementations for earlier versions of JAXP is used, this exception will be thrown. |

reset
public void reset ()
Reset this DocumentBuilder
.
EntityResolver
and ErrorHandler
instances associated with this DocumentBuilder
and sets all internal
properties to false including those set by the DocumentBuilderFactory
when
this DocumentBuilder
was created.
setEntityResolver
public abstract void setEntityResolver (EntityResolver er)
Specify the EntityResolver
to be used to resolve
entities present in the XML document to be parsed. Setting
this to null
will result in the underlying
implementation using it's own default implementation and
behavior.
Parameters | |
---|---|
er |
EntityResolver : The EntityResolver to be used to resolve entities
present in the XML document to be parsed. |
setErrorHandler
public abstract void setErrorHandler (ErrorHandler eh)
Specify the ErrorHandler
to be used by the parser.
Setting this to null
will result in the underlying
implementation using it's own default implementation and
behavior.
