Converting DOM to text

Converting DOM to text

2003-01-20 - By Sean Leblanc

Hello,

I am trying to use the samples to convert DOM I already have in memory to a
string of text.

I'm looking at the DOM2DOM sample, and trying to use it, but I get this
error:

javax.xml.transform.TransformerException: org.w3c.dom.DOMException:
HIERARCHY_REQUEST_ERR: An attempt was made to insert a node where it is not
permitted.

Here is the code. The variable "document" is passed in.

// Get ready for a transformation:
DOMSource xmlDomSource = new DOMSource(document);
DocumentBuilderFactory dFactory =
DocumentBuilderFactory.newInstance();
dFactory.setNamespaceAware(true);
DocumentBuilder dBuilder = dFactory.newDocumentBuilder();
TransformerFactory tFactory = TransformerFactory.newInstance();
// Get our XSL file, transform into source:
File xslFile = new File("test.xsl");
System.out.println("Exists? " + xslFile.exists());
Document xslDoc = dBuilder.parse(xslFile);
DOMSource xslDomSource = new DOMSource(xslDoc);

// Set the systemId: note this is actually a URL, not a local
filename
xslDomSource.setSystemId("");

// Process the stylesheet DOMSource and generate a Transformer.
Transformer transformer = tFactory.newTransformer(xslDomSource);

// Create an empty DOMResult for the Result.
DOMResult domResult = new DOMResult();

// Perform the transformation, placing the output in the
DOMResult.
transformer.transform(xmlDomSource, domResult);

//Instantiate an Xalan XML serializer and use it to
serialize the output DOM to System.out
// using a default output format.
Serializer serializer = SerializerFactory.getSerializer

(OutputProperties.getDefaultMethodProperties("xml"));
serializer.setOutputStream(System.out);
serializer.asDOMSerializer().serialize(domResult.getNode());
