Hi 1st Question, be gentle.
I'm trying to use javax.xml.transform.Transformer to format some xml string to be indented / spaceless between the tags. If there are no spaces between the tags, it works ok. If there are it acts weird. I'll post an example. I tried to follow up on the following topic : http://forums.sun.com/thread.jspa?messageID=2054303#2699961. No success.
Code to follow :
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setIgnoringElementContentWhitespace(true);
DocumentBuilder builder = factory.newDocumentBuilder();
DOMImplementation domImpl = builder.getDOMImplementation();
DOMImplementationLS ls = (DOMImplementationLS) domImpl.getFeature("LS", "3.0");
LSInput in = ls.createLSInput();
in.setByteStream(new ByteArrayInputStream(input.getBytes()));
LSParser parser = ls.createLSParser(DOMImplementationLS.MODE_SYNCHRONOUS,
"http://www.w3.org/2001/XMLSchema");
Document xmlInput = parser.parse(in);
StringWriter stringWriter = new StringWriter();
StreamResult xmlOutput = new StreamResult(stringWriter);
TransformerFactory f = TransformerFactory.newInstance();
f.setAttribute("indent-number", 2);
Transformer transformer = f.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
transformer.transform(new DOMSource(xmlInput), xmlOutput);
If there's no interruption between tags
input : <tag><nested> hello </nested></tag>
output :
<tag>
<nested> hello </nested>
</tag>
If there is :
input : <tag> <nested> hello </nested></tag>
output :
<tag> <nested> hello </nested>
</tag>
JVM 1.6.
Is something obvious wrong here ?
