Well, I'm not sure there's much to help with anymore. If the document
isn't rendered correctly when the whitespace is formatted, then we'll
just have to change the source document. I'm unable to reproduce the
rowspan/colspan issue after formatting the document. So, really the
only thing left is the broken formatting after a DOM manipulation. In
this case the merging of the document heads.
As requested, here's my code. It's somewhat spread out because I have
more of a framework than a single program. I've pieced it together into
an attached .txt file.
Thanks,

Oops, forgot the attachments.
I wasn't able to reproduce the rendering difference by just
removing the rowspan and colspan attributes. I guess the
pretty printing affected this.

Hopefully this
will resolve issues like this. The new one is not supposed
to have tables.
As for what I'm doing... I'm taking a style template page
and merging
it with my generated content. The style template display
is breaking
because of rowspan/colspan attributes as well as whitespace
differences.
You can see this in the attached files. template.html is the
template, and new.html is the output after merging. I removed the
merged(generated) body content so that you just see the template
differences. You can also see the issue I was talking about in my
response to your pretty print suggestion where the
serialization isn't
correct where the two head's are merged.(I left the merged head
content in there)
It's easier to see the code changes if you reformat the
html, but this
also causes rendering differences.

Thanks for the response Mike,
I still have a dilemma though, because if I set Xerces'
http://apache.org/xml/features/nonvalidating/load-external-dtd
to false, it stops adding the rowspan="1"'s, but it also removes
all the 's from the document. Do you have any
suggestions?
I'm going to manually remove the added attributes, but I don't
really like this solution.

Hi Evan,
Thi is not DOM4J doing this I dont think, as it does not
understand HMTL!
Perhaps it is a validating SAX Parser, or someting else in
the parse
chain

DOM4J seems to be adding attributes to my document. I
don't know if
this is when it's loaded, or when it's serialized, and I'd
guess it
has something to do with the XHTML DTD.
It's adding rowspan="1" and colspan="1" to my td's and like
clear="none" or something like that to br's. I'm using a
pre-existing style document, and this is changing the layout.
I know it sounds kind of silly, but it is changing how
the browsers
render the content. Is there a way to turn this off?

This is also relevant:

pw.flush();
}
public static void unfixNamespaces(Document doc, Namespace original){

if(removeNamespaces && original != null)
setNamespaces(root.content(), original);//recursive
}
Here's the template merging code:
public void modify(DOMBase base) throws Exception{
Element body = base.body;
Element head = base.head;
String title = base.getTitle();
Date modified = base.getModified();
Document styleDoc = base.getDocument(new

base.setDoc(styleDoc, false);
body.setQName( new QName( "div", body.getNamespace() ) );
List l = body.attributes();
for(int i=0; i<l.size(); i++){
Attribute att = (Attribute)l.get(i);
if( mergeAttributes.contains( att.getName().toLowerCase() ) ){
base.body.addAttribute( att.getName(),
base.body.attributeValue( att.getName() ) + att.getValue() );
}
}
if(body != null) base.replaceComment("content", body);
if(base.head != null && head != null)
base.head.content().addAll(head.content());
base.setTitle(base.getTitle()+title);
String filename = "generated document";
if(base.uri != null){
if( "file".equals(base.uri.getScheme()) ) filename = new
File(base.uri).getName();
}
base.replaceComment("url", filename);
base.replaceComment("last_update", ""+modified);
}
