Constructor Detail

XMLUtils

public XMLUtils()

Method Detail

toXml

public static String toXml(Document dom)

Converts a DOM to an XML string.

Parameters:

dom - the dome object to convert

Returns:

A string representation of the document

getTransformer

public static Transformer getTransformer()
                                  throws TransformerConfigurationException

Returns:

a new XSLT transformer

Throws:

TransformerConfigurationException - if no TransformerFactory can be located in the runtime environment.

toDocument

public static org.dom4j.Document toDocument(Object obj,
                                            MuleContext muleContext)
                                     throws Exception

Throws:

Exception

toDocument

public static org.dom4j.Document toDocument(Object obj,
                                            String externalSchemaLocation,
                                            MuleContext muleContext)
                                     throws Exception

Converts an object of unknown type to an org.dom4j.Document if possible.

Returns:

null if object cannot be converted

Throws:

org.dom4j.DocumentException - if an error occurs while parsing

Exception

toW3cDocument

public static Document toW3cDocument(Object payload)
                              throws Exception

Converts a payload to a Document representation.

Reproduces the behavior from toDocument(Object, MuleContext) which works converting to Document.

Parameters:

payload - the payload to convert.

Returns:

a document from the payload or null if the payload is not a valid XML document.

Throws:

Exception

toXMLStreamReader

public static XMLStreamReader toXMLStreamReader(XMLInputFactory factory,
                                                Object obj)
                                         throws XMLStreamException

Returns an XMLStreamReader for an object of unknown type if possible.

Returns:

null if no XMLStreamReader can be created for the object type

Throws:

XMLStreamException

toXmlSource

public static Source toXmlSource(XMLInputFactory xmlInputFactory,
                                 boolean useStaxSource,
                                 Object src)
                          throws Exception

Convert our object to a Source type efficiently.

Throws:

Exception

toStreamSource

public static Source toStreamSource(XMLInputFactory xmlInputFactory,
                                    boolean useStaxSource,
                                    InputStream stream)
                             throws XMLStreamException

Throws:

XMLStreamException

copy

public static void copy(XMLStreamReader reader,
                        XMLStreamWriter writer)
                 throws XMLStreamException

Copies the reader to the writer. The start and end document methods must be handled on the writer manually. TODO: if the namespace on the reader has been declared previously to where we are in the stream, this probably won't work.

Parameters:

reader -

writer -

Throws:

XMLStreamException

copy

public static void copy(XMLStreamReader reader,
                        XMLStreamWriter writer,
                        boolean fragment)
                 throws XMLStreamException

Throws:

XMLStreamException

selectOne

public static Node selectOne(String xpath,
                             Node node)
                      throws XPathExpressionException

Select a single XML node using an Xpath

Parameters:

xpath - the XPath expression to evaluate

node - the node (or document) to exaluate on

Returns:

the result of the evaluation.

Throws:

XPathExpressionException - if the XPath expression is malformed and cannot be parsed

selectValue

public static String selectValue(String xpath,
                                 Node node)
                          throws XPathExpressionException

Select a single XML String value using an Xpath

Parameters:

xpath - the XPath expression to evaluate

node - the node (or document) to evaluate on

Returns:

the result of the evaluation.

Throws:

XPathExpressionException - if the XPath expression is malformed and cannot be parsed

select

public static List<Node> select(String xpath,
                                Node node)
                         throws XPathExpressionException

Select a set of Node objects using the Xpath expression
