Java: convert StreamResult to DOM

问题:

I am performing a xslt transformation from one xml format to another with saxon and xslt, after what transforming the result xml into Java DOM to work with it further:

System.setProperty("javax.xml.transform.TransformerFactory", "net.sf.saxon.TransformerFactoryImpl");
TransformerFactory tFactory = TransformerFactory.newInstance();

Transformer transformer = tFactory.newTransformer(new StreamSource(new File("xslt.xsl")));
transformer.transform(new StreamSource(new File(inputXML)),
                                  new StreamResult(new File (outputXML)));

DocumentBuilder documentBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document document = documentBuilder.parse(outputXML);

What I don't like in this situation, is creating intermediate outputXML file. Is it possible to avoid its creating?

回答1:

DocumentResult result = new DocumentResult();

transformer.transform( new StreamSource(new File(inputXML)), result );

Document transformedDoc = result.getDocument();

The answer was provided by @Andreas. If someone is interested, the result code snippet in my case looked like this:

System.setProperty("javax.xml.transform.TransformerFactory", "net.sf.saxon.TransformerFactoryImpl");
TransformerFactory tFactory = TransformerFactory.newInstance();

DOMResult xmlResult = new DOMResult();
Transformer transformer = tFactory.newTransformer(new StreamSource(new File("xslt.xsl")));
        transformer.transform(new StreamSource(new File(outputXML)),
                              xmlResult);

Document document = (Document) xmlResult.getNode();
