Here's one more approach, using keys.

Basically we need some way to group together each set of non-paragraph
elements for processing into a single table.  I do it by giving each of
these elements (common | less-common | rare | very-rare) a key equal to the
generated id of their first preceding paragraph.  So in a consecutive set of
these elements, they'll all have the same key.  The processing is kicked off
by the paragraph template - basically if a paragraph is followed by a
non-paragraph, it processes all elements with key equal to it's own
generated id.  

So:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:output method="html" indent="yes"/>
	
<xsl:key name="npgrouper" match="common | less-common | rare | very-rare"
use="generate-id(preceding-sibling::paragraph[1])"/>

<xsl:template match="/">
	<html>
		<xsl:apply-templates/>
	</html>
</xsl:template>

<xsl:template match="paragraph">
	<p>
		<xsl:apply-templates/>
	</p>
	<xsl:if test="following-sibling::*[1][name() != 'paragraph']">
	<!-- I assume there aren't any other non paragraph elements floating
about, but it 
		would be safer to spell out the names common, less-common,
etc -->
		<table>
			<xsl:apply-templates
select="key('npgrouper',generate-id(.))" mode="output"/>
		</table>
	</xsl:if>
</xsl:template>

<xsl:template match="common | less-common | rare | very-rare" mode="output">
	<xsl:copy-of select="."/>
</xsl:template>

<xsl:template match="common | less-common | rare | very-rare"/>

</xsl:stylesheet>

Gives me output of:


<html>
	<p>blabla</p>
	<table>
		<common>
			<paragraph>blabla</paragraph>
		</common>
		<less-common>
			<paragraph>blabla</paragraph>
		</less-common>
		<rare>
			<paragraph>blabla</paragraph>
			<paragraph>blabla</paragraph>
		</rare>
	</table>
	<p>blabla</p>
	<p>blabla</p>
	<table>
		<common>
			<paragraph>blabla</paragraph>
		</common>
		<very-rare>
			<paragraph>blabla</paragraph>
			<paragraph>blabla</paragraph>
		</very-rare>
	</table>
	<p>blabla</p>
</html>

Which I think is what you want.

Hope this helps,
David.
