Dumb XSL question

[babysimon]

For some reason XSL just won't stick in my brain, so I have to ask my friends list.

If I have a document which contains AAA nodes and I want to transform them to BBB nodes I can do something like:

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

But suppose I want to replace every AAA immediately followed by a CCC (throwing the CCC away)? Something like

	<xsl:template match="AAA/following-sibling::CCC[1]">
		<BBB><xsl:apply-templates/></BBB>
	</xsl:template>

is my guess, but then I'm told "Only child:: and attribute:: axes are allowed in match patterns!"

Anyone got any clues? I'm trying to pretend this isn't just directed at lozette...
