I'm using a home grown serializer (DOMWriter) to write my xml to a file. I'm curious as to what other people are using. Basically I use the following print method and helper method normalize.
public void print(Node node) throws DoraException {
// is there anything to do? if (node == null) { return; }
int type = node.getNodeType();
switch (type) { // print document case Node.DOCUMENT_NODE: { if (!canonical) { String Encoding = DOMWriter.getWriterEncoding();
if (Encoding.equalsIgnoreCase("DEFAULT")) { Encoding = "UTF-8"; } else if (Encoding.equalsIgnoreCase("Unicode")) { Encoding = "UTF-16"; } else { Encoding = MIME2Java.reverse(Encoding); }
out.println("<?xml version=\"1.0\" encoding=\"" + Encoding + "\"?>"); } // print(((Document)node).getDocumentElement());
NodeList children = node.getChildNodes();
for (int iChild = 0; iChild < children.getLength(); iChild++) { print(children.item(iChild)); } out.flush(); break; }
// print element with attributes case Node.ELEMENT_NODE: { out.print('<'); out.print(node.getNodeName()); Attr attrs[] = sortAttributes(node.getAttributes());
for (int i = 0; i < attrs.length; i++) { Attr attr = attrs[i];
out.print(' '); out.print(attr.getNodeName()); out.print("=\""); out.print(normalize(attr.getNodeValue(), canonical)); out.print('"'); } out.print('>'); NodeList children = node.getChildNodes();
if (children != null) { int len = children.getLength();
for (int i = 0; i < len; i++) { print(children.item(i)); } } break; }
// handle entity reference nodes case Node.ENTITY_REFERENCE_NODE: { if (canonical) { NodeList children = node.getChildNodes();
if (children != null) { int len = children.getLength();
for (int i = 0; i < len; i++) { print(children.item(i)); } } } else { out.print('&'); out.print(node.getNodeName()); out.print(';'); } break; }
// print cdata sections case Node.CDATA_SECTION_NODE: { if (canonical) { out.print(normalize(node.getNodeValue(), canonical)); } else { out.print("<![CDATA["); out.print(node.getNodeValue()); out.print("]]>"); } break; }
// print text case Node.TEXT_NODE: { // out.print(node.getNodeValue()); out.print(normalize(node.getNodeValue(), canonical)); break; }
// print processing instruction case Node.PROCESSING_INSTRUCTION_NODE: { out.print("<?"); out.print(node.getNodeName()); String data = "">
if (data != null && data.length() > 0) { out.print(' '); out.print(data); } out.print("?>"); break; } }
if (type == Node.ELEMENT_NODE) { out.print("</"); out.print(node.getNodeName()); out.print('>'); }
out.flush();
} // print(Node)
public static String normalize(String s, boolean canonical) { StringBuffer str = new StringBuffer();
int len = (s != null) ? s.length() : 0;
for (int i = 0; i < len; i++) { char ch = s.charAt(i);
switch (ch) { case '<': { str.append("<"); break; }
case '>': { str.append(">"); break; }
case '&': { str.append("&"); break; }
case '"': { str.append("""); break; }
case '\'': { str.append("'"); break; } /* case '\r': case '\n': { if (canonical) { str.append("&#"); str.append(Integer.toString(ch)); str.append(';'); break; } // else, default append char } */ default: { str.append(ch); } } }
return(str.toString());
