Assuming <br> is the only tag that will be in p . Youl could split on each <br> tags to get an array of elements.
NOTE: </br> is invalid.
var strings = 'some text <br>select this <br/>and not this'.split(/<br\/?>/i);
alert(strings.length); //3

Well </br> is not valid HTML as the br element is an empty element.
As far as XPath is concerned, you could use the path //p/br[1]/following-sibling::node()[1][self::text()] to select the text node with the string value select this and to select an empty node set in case the following sibling of the first br child is not a text node.
