XPath won't select outer element

[Dave Abrahams <dave@…>]

>>> print HTML('<foo>bar</foo>') | Transformer('foo').remove()
<foo>bar</foo>

This behavior is by design.

When you select from a snippet such as "<foo>bar</foo>", <foo> is the context node for the XPath expression. You would match it with the expression “.”, but the expression “foo” actually tells it to look for any immediate child elements with the tag name “foo”.

I've updated the docstring of Stream.select in r690 to clarify this.

As an addendum, '.' is the default selection since r689:

>>> print HTML('<foo>bar</foo>') | Transformer().unwrap()
bar
