Method Details

newEmptyDocument

public static Document newEmptyDocument()

Create a new empty document.

Returns:

a new empty document

newDocumentBuilder

public static DocumentBuilder newDocumentBuilder()

Create a new DocumentBuilder configured for namespaces but not validating.

Returns:

a new, configured DocumentBuilder

newTransformerHandler

public static TransformerHandler newTransformerHandler()
                                                throws TransformerConfigurationException

Create a new TransformerHandler.

Returns:

a new TransformerHandler

Throws:

TransformerConfigurationException

newTransformer

public static Transformer newTransformer(Source source)
                                  throws TransformerConfigurationException

Create a new Transformer from an XSLT.

Parameters:

source - the source of the XSLT.

Returns:

a new Transformer

Throws:

TransformerConfigurationException - if there was a problem creating the Transformer from the XSLT

newInputSource

public static InputSource newInputSource(Reader reader,
 String systemId)

Create an InputSource from a Reader. The systemId will be wrapped for use with JSTL's EntityResolver and UriResolver.

Parameters:

reader - the source of the XML

systemId - the system id

Returns:

a configured InputSource

newXMLReader

public static XMLReader newXMLReader(XmlUtil.JstlEntityResolver entityResolver)
                              throws ParserConfigurationException,
SAXException

Create an XMLReader that resolves entities using JSTL semantics.

Parameters:

entityResolver - for resolving using JSTL semantics

Returns:

a new XMLReader

Throws:

ParserConfigurationException - if there was a configuration problem creating the reader

SAXException - if there was a problem creating the reader

newSAXSource

public static SAXSource newSAXSource(Reader reader,
 String systemId,
 XmlUtil.JstlEntityResolver entityResolver)
                              throws ParserConfigurationException,
SAXException

Create a SAXSource from a Reader. Any entities will be resolved using JSTL semantics.

Parameters:

reader - the source of the XML

systemId - the system id

entityResolver - for resolving using JSTL semamtics

Returns:

a new SAXSource

Throws:

ParserConfigurationException - if there was a configuration problem creating the source

SAXException - if there was a problem creating the source
