DocumentBuilder

public abstract 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.

Returns
`boolean`	true if this parser is configured to understand namespaces; false otherwise.

isValidating

Added in API level 1

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.

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.
