document to string

Is it possible in java (with a mixture of ACL if needed) to convert a DOM document object to a string (without writing the document to a file and reading the file in)?

To a certain extent I can do this, but a couple of things are causing problems.

I want the string to have the xml declaration and (less important) the processing instruction Arbortext adds ( like ). And most importantly, I need the resulting string to have only user-specified attributes, no DTD/Schema provided defaults. And by attributes, I mean both true element attributes as well as "attributes" to Arbortext-specific processing instructions like _font and _touchup.

Any help would be greatly appreciated.

Hi, Brian...

Given your requirements for somewhat finer control over the markup, you
might consider running the DOM document through an XSLT transform to get the
result you want. This would be mostly an identity transform, but would
allow you to control settings such as the presence of the XML declaration.

You'd also be able to override specific things, such as suppressing
attributes that correspond to their default values. It might be somewhat
tedious to generate the overrides for default attributes, depending on the
size of your DTD/Schema, though there are ways this could be automated, such
as an XSLT transform of an XML Schema or using ACL to access such
information in a DTD.

I just found a way to do what I was looking for. It appears to do
everything I wanted and needed. Thanks to Brandon for his reply, which
I got just as I had verified my solution was working. Here's the code I
used, which will convert any (as far as I know) node, including a
Document object, into a string:

public static String toString(Node node) {
String oid = ((ANode) node).getFirstOID();
int flags = ARange.MARKUP_FORCE_PI | ARange.MARKUP_CHAR;
if(Acl.func("oid_type", oid).equals("9")) {
// XML comment
return Acl.func("oid_content", oid, "1");
} else {
Node nNode;
Document doc;
if(node.getNodeType() == Node.DOCUMENT_NODE) {
doc = (Document)node;
nNode = doc.getDocumentElement();
flags |= ARange.MARKUP_HEADER;
} else {
nNode = node;
doc = node.getOwnerDocument();
}

Range range = ((DocumentRange) doc).createRange();
range.setStartBefore(nNode);
range.setEndAfter(nNode);
return ((ARange) range).toMarkupStringEx(flags);
}
}

Thanks,
Brian
