Basically, just select the node set that you want.  Something like this
is simple (I am assuming that the ruledef elements are immediate
children of a "root" element) -

<xsl:template match="/root">
<results>
<xsl:apply-templates select='ruledef[@pageeject="yes"]' mode='eject'/>
</results>
</xsl:template>

<xsl:template match='ruledef' mode='eject'>
   ---Fire rule here ---
</xsl:template>

Your example shows one of the really nice things about xslt, but one
that can be surprising to newcomers.  The select expression applies the
test to each candidate node, and returns only the set of nodes that pass
the test.  So you do not need to "loop" or do anything else - the system
just automatically does what you want (you _could_ write a "loop" in
several ways, including using xsl:for-each, but there is no point in
doing so in this case).

BTW, I only used a "mode" attribute in case you might want to have other
templates for ruledef nodes besides the pageeject template.  If you do
not, you could omit the "mode" attributes in both places.
