Ugh, SAX based is faster and cleaner. IMHO, of course. SAX based taglib
combining is done in parallel, compiled, and just plain works. The code is
simple. Really simple.
XSLT is not simpler for developers. Thats the boat being missed here.
my $el = { Name => "foo" };
$self->start_element($el);
... # process blah
$self->end_element($el);
vs:
<xsl:template name="...">
...
</xsl:template>
<xsl:template match="blah">
<foo>
<xsl:apply-templates name="..."/>
</foo>
</xsl:template>
