br
The br element does not define a corresponding xml node, but lets the parser decide how to transform the html tag. The parser inserts a forced line break. Depending on the text structure, it will either create a new CData node that contains the line break, or append the line break to a text sibling of the "br" node..

If the previous node on the same level as the br tag is a text node, it adds a new line to the end of the text node text.
