DOM Level 1 Compatibility Checker
Thursday October 19th, 2000
Actually my nightly of Mozilla fails over half of these tests. I think that most of the failures are due to Mozilla's treatment of whitespace between tags as nodes, which the author says is "highly annoying", and I happen to agree. Why does Mozilla treat whitespace between tags as a node?

This prolem is a bit more involved. Standard says: An XML processor must always pass all characters in a document that are not markup through to the application. A special attribute named xml:space may be attached to an element to signal an intention that in that element, white space should be preserved by applications.
So Mozilla does it in a standard way. But I agree that it would be much more convenient (and also standard) remove non-significant whitespaces.
Maybe it would be a good idea to look at XML canonization: <http://www.w3.org/TR/2000/WD-xml-c14n-20001011> (only a working draft at this moment) and use from it everything which does not impose too large processing penalty
#3 Whitespace should stay

The whitespace issue depends upon whether the documents is validated or not. In the case of no validation, all white-space should be kept. This is because there is no way to know if an element contains text as a child.
Once a document is validated against a DTD or a schema, then we can decide which whitespace is there as content, and which is prety-printing stuff as the document structure tells us what children each element should have. At this point, the DOM should not contain any extraneous text nodes.
Does this make sence?

I am not so sure that there should not be some cannonization. It would make the system more user friendly
You can always use entities if you want for some reasons the whitespace.
Or (from the spec) : A special attribute named xml:space may be attached to an element to signal an intention that in that element, white space should be preserved by applications. So if the XML document author cares about whitespaces he can just attach this attribute to the document root and Mozilla must behave accordingly.
