I want to bundle a JAXP compliant XML parser with my application, with
the requirement that the jar file is as small as possible. From what I
can tell, between Crimson, Xerces1 and Xerces2, I am using Crimson
because of its smaller jar size. However, if there is a way to
distribute Xerces2 without all the classes that I don't use so that it
reduces the size of the jar, that would be preferable.
Now that I'm using Crimson, I have a technical question about
serialization, and apparently this list is the only forum for Crimson
discussion.
I can serialize a Document fine, but I haven't figured out how to
serialize any other type of DOM Node. My code is:
----------------------------------------------------------------------
public static String serializeToString(Node aNode) {
String myResult = null;
// Crimson implementation
StringWriter myStringWriter = new StringWriter();
short myNodeType = aNode.getNodeType();
try {
switch (myNodeType) {
case Node.DOCUMENT_NODE :
((XmlDocument)
aNode).write(myStringWriter, XMLUtils.ENCODING_UTF_8);
break;
default :
XmlDocument myXmlDocument =
(XmlDocument) aNode.getOwnerDocument();
myXmlDocument.writeChildrenXml(
myXmlDocument.createWriteContext(myStringWriter, 0));
break;
}
} catch (IOException e) {
String myMsg = "Unable to serialize DOM Node: "
+ e.getMessage();
throw new RuntimeException(myMsg);
}
myResult = myStringWriter.toString();
return myResult;
}
----------------------------------------------------------------------
However, the default non-Document case returns an empty String. From
what I can tell this is because Crimson does not see any children of the
given DOM Node and exits early without serializing anything.
Specifically, I would like to serialize an Element. Do I have to write a
hack that creates a new XmlDocument, import the Element, then serialize
the XmlDocument without the XML header information currently hard coded
in XmlDocument.write() ?
cheers,
Simon
