Constructor Detail

Transformer

public Transformer()
            throws TransformerConfigurationException

Transformer constructor without stylesheet.

Throws:

TransformerConfigurationException

Transformer

public Transformer(Source source)
            throws TransformerConfigurationException

Constructs a transformer with a stylesheet in form of Source.

Examples:

File file

new Transformer(new javax.xml.transform.stream.StreamSource(file));

Reader reader

new Transformer(new javax.xml.transform.stream.StreamSource(reader));

URL url

new Transformer(new javax.xml.transform.stream.StreamSource(url.openStream()));

iDOM or DOM dom

new Transformer(new javax.xml.transform.dom.DOMSource(dom));

See javax.xml.transform.stream.StreamSource and javax.xml.transform.dom.DOMSource

Throws:

TransformerConfigurationException

Method Detail

enableOutputDocType

public final void enableOutputDocType(boolean enable)

Sets whether to output the doc type. Default: true.

Useful only if Document is used in transform(), e.g., transform(Document, Result). If not, you have to set OutputKeys.DOCTYPE_SYSTEM and OutputKeys.DOCTYPE_PUBLIC explicitly (thru getTransformer()).

getTransformer

public final Transformer getTransformer()

Returns the JAXP transformer encapsulated by this object. Then, you can use it to set properties, listener and so on.

Notice: OutputKeys.DOCTYPE_SYSTEM and OutputKeys.DOCTYPE_PUBLIC are set automatically if outDocType is true when constructing this object and Document is used to transform.

transform

public final void transform(Source source,
                            Result result)
                     throws TransformerException

Transforms from a source to a result. and javax.xml.transform.dom.DOMSource

Parameters:

source - the source

result - the result

Throws:

TransformerException

See Also:

transform(Document, Result)

transform

public final void transform(Document doc,
                            Result result)
                     throws TransformerException

Transforms from an iDOM document to a result.

Examples:

File file

transformer.transform(doc, new javax.xml.transform.stream.StreamResult(file));

Writer writer

transformer.transform(doc, new javax.xml.transform.stream.StreamResult(writer));

URL url

No simple way yet.

iDOM or DOM dom

transform(Source) and transform(Document).

String systemId

transformer.transform(doc, new javax.xml.transform.stream.StreamResult(systemId));

See javax.xml.transform.stream.StreamResult and javax.xml.transform.dom.DOMResult

Parameters:

doc - the source document

result - the result

Throws:

TransformerException
