Method Detail

newInstance

public static DOMBuilder newInstance()
                              throws ParserConfigurationException

Throws:

ParserConfigurationException

newInstance

public static DOMBuilder newInstance(boolean validating,
                     boolean namespaceAware)
                              throws ParserConfigurationException

Throws:

ParserConfigurationException

parse

public static Document parse(Reader reader)
                      throws SAXException,
                             IOException,
                             ParserConfigurationException

Creates a DocumentBuilder and uses it to parse the XML text read from the given reader. A non-validating, namespace aware parser which does not allow DOCTYPE declarations is used.

Parameters:

reader - the reader to read the XML text from

Returns:

the root node of the parsed tree of Nodes

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.

IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

ParserConfigurationException - if a DocumentBuilder cannot be created which satisfies the configuration requested.

parse

public static Document parse(Reader reader,
             boolean validating,
             boolean namespaceAware)
                      throws SAXException,
                             IOException,
                             ParserConfigurationException

Creates a DocumentBuilder and uses it to parse the XML text read from the given reader, allowing parser validation and namespace awareness to be controlled. Documents are not allowed to contain DOCYTYPE declarations.

Parameters:

reader - the reader to read the XML text from

validating - whether to validate the XML

namespaceAware - whether the parser should be namespace aware

Returns:

the root node of the parsed tree of Nodes

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.

IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

ParserConfigurationException - if a DocumentBuilder cannot be created which satisfies the configuration requested.

parse

                      throws SAXException,
                             IOException,
                             ParserConfigurationException

Creates a DocumentBuilder and uses it to parse the XML text read from the given reader, allowing parser validation, namespace awareness and permission of DOCTYPE declarations to be controlled.

Parameters:

reader - the reader to read the XML text from

validating - whether to validate the XML

namespaceAware - whether the parser should be namespace aware

allowDocTypeDeclaration - whether the parser should allow DOCTYPE declarations

Returns:

the root node of the parsed tree of Nodes

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.

IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

ParserConfigurationException - if a DocumentBuilder cannot be created which satisfies the configuration requested.

parseText

public Document parseText(String text)
                   throws SAXException,
                          IOException,
                          ParserConfigurationException

A helper method to parse the given text as XML.

Parameters:

text - the XML text to parse

Returns:

the root node of the parsed tree of Nodes

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.

IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

ParserConfigurationException - if a DocumentBuilder cannot be created which satisfies the configuration requested.
