Method Detail

parse

public Document parse(InputStream is)
               throws SAXException,
                      IOException

Parse the specified input stream and return a DOM Document. Prefer the version of this method that specifies a system ID, in order to resolve external references correctly.

Parameters:

is - an XML input stream

Throws:

IllegalArgumentException - if the input stream is null

SAXException

IOException

parse

public Document parse(InputStream is,
             String systemId)
               throws SAXException,
                      IOException

Parse the specified input stream and return a DOM Document.

Parameters:

is - an XML input stream

systemId - the system ID of the XML document

Throws:

IllegalArgumentException - if the input stream is null

SAXException

IOException

parse

public Document parse(String uri)
               throws SAXException,
                      IOException

Parse the content of the specified URI and return a DOM Document.

Parameters:

uri - an XML system ID

Throws:

IllegalArgumentException - if the URI is null

SAXException

IOException

parse

public Document parse(File f)
               throws SAXException,
                      IOException

Parse the specified file and return a DOM Document.

Parameters:

f - the XML file

Throws:

IllegalArgumentException - if the file is null

SAXException

IOException

parse

public abstract Document parse(InputSource source)
                        throws SAXException,
                               IOException

Parse the specified input source and return a DOM Document.

Parameters:

source - the input source

Throws:

IllegalArgumentException - if the input source is null

SAXException

IOException

isNamespaceAware

public abstract boolean isNamespaceAware()

Indicates whether this document builder is XML Namespace aware.

isValidating

public abstract boolean isValidating()

Indicates whether this document builder will validate its input.

setEntityResolver

public abstract void setEntityResolver(EntityResolver er)

Sets the SAX entity resolver callback used to resolve external entities in the XML document(s) to parse.

Parameters:

er - an entity resolver

setErrorHandler

public abstract void setErrorHandler(ErrorHandler eh)

Sets the SAX error handler callback used to report parsing errors.

Parameters:

eh - the error handler

newDocument

public abstract Document newDocument()

Creates a new, empty DOM Document. To create a document with a root element and optional doctype, use the DOMImplementation instead.

getDOMImplementation

public abstract DOMImplementation getDOMImplementation()

Returns the DOM implementation.

reset
