<map:parameter name="xpath"
value="/*[local-name()='html']/*[local-name()='meta']/*[local-name()='title']|
/*[local-name()='html']/*[local-name()='meta']/*[local-name()='description']|
/*[local-name()='html']/*[local-name()='meta']/*[local-name()='title']|
/*[local-name()='html']/*[local-name()='meta']/*[local-name()='publisher']|
*/*[local-name()='html']/*[local-name()='body']/*[local-name()='p']"/>

Why does the "p" entry start with an asterisk?

You could get the "body", then parse out the "p" in a transformation
later.  Something has to handle the filtering, and it is usually best
to reduce the amount of data as early in the process as possible, but
the data outside the "p" elements may not add much,  you may want that
data later, it would move the processing from the "directory"
generator to a transformer without increasing the CPU cycles much, and
it could simplify your code.

That should be:
<xsl:template match="xhtml:p">
