For interest sake, given the original problem...



XMetaL will "fix" it as follows when opening the document in "well formed" mode (no DTD/XSD provided):



It also displays the following in the "validation log" (note that each of the errors is clickable and takes you to that node so there is context here without it actually being included as text in the error):

* Bad start tag. Expected ">".

* Bad start tag. Expected ">".

* Bad start tag. Expected ">".

* Implied missing end-tag </three>

* Implied missing end-tag </two>

* Ignoring end-tag </tree>

* Implied missing end-tag </__two>


Note that when a DTD or XSD Schema is available the results will be different because a lot of things can be implied from the schema's rules.

That's not exactly what I got with Oxygen 13.1. How can we double check this ?

In the oXygen Outline view the fragment

Formatted for readability that will be:


The </tree> tag will be actually ignored, but it still divides eventual text nodes before and after that.

	   removing the html head and body implied in the html context results in a

	   meaning implied by the original markup. The important thing is that
	   html5 specifies a deterministic algorithm that returns a tree. Unless
