I want to insert a line feed into an XML document, serialize it to a file, and then parse it to a DOM document for use in an XSL transform (applying a sytlesheet). Parsing always throws the following exception.
org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x10) was found in the element content of the document.
I have a feeling I'm inserting the wrong character for what I want. Does anyone have a suggestion?
Hex 0x10 isn't a line feed (\n); *decimal* 10 (0xA) is.
Using "\n", rather than "\u0010", doesn't cause the exception, but it doesn't get me the desired line feed when I transform the XML to HTML using an XSL stylesheet.
All whitespace (including \n) gets normalized to spaces. To get such a character into your XML text you need to use a character entity: 

Test code:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); DocumentBuilder db = dbf.newDocumentBuilder(); Document doc = db.newDocument(); Element test = doc.createElement("Test"); test.appendChild(doc.createTextNode("before"));
test.appendChild(doc.createTextNode("\u0010"));
Replace "\u0010" with "
".
test.appendChild(doc.createTextNode("after"));
doc.appendChild(test);
FileOutputStream fos = new FileOutputStream("C:/myoutput.xml");
Transformer t = transFact.newTransformer(); // identity transform
// not necessary
t.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
Node node = doc.getDocumentElement();
DOMSource source = new DOMSource(node);
StreamResult result = new StreamResult(fos);
t.transform(source, result);
fos.close();
db.parse(new File("C:/myoutput.xml"));

My apologies...
OK, I tried createTextNode(Character.toString('\u0010')) in my java code. Serialization may happen correctly, however when I need to parse back into a document I get an exception.
org.xml.sax.SAXParseException: An invalid XML character (Unicode: 0x10) was found in the element content of the document.
What's the issue?
Thanks, Derrick

Whether working with DOM or SAX, the answer is the same: just put the characters you want into a Text node's string value, as it would appear if you had obtained the DOM by parsing a document. It's the serializer's responsibility to render that appropriately when you output XML.
If you want a line break, XML's representation of line break is the newline character (ASCII/Unicode 10). The serializer may convert that to CRLF if that's the appropriate representation of line break on your system. (Note that XML parsers must convert CRLF, CR, or LF to newline.)
If you really want a carriage return character, use it (ASCII/Unicode 13). The serializer will recognize that the only way you can have this character in XML content is if it was escaped, and will render it appropriately.
