FW: Dealing with mixed content

Hello,

Apologies inadvance for the 'XSL 101' nature of this question but I'm new to
XSL.

I receive XML from an automate conversion process, over which I have no
control.

Example:

	<block >Text <font font-weight="bold">more text</font> more
text<sr/>more text. <hr/>more text <sr/>more text.</block>

The <sr/> elements can be ignored but the <hr/> element indicates that an
exisitng <P> element should be terminated and a new <P> element started.
