Re: [xsl] xsl != not working?

I think this is a FAQ about the "//" abbreviation.

What you probably need is:

(//h2)[1]/text() != text()

But checking for node identity using the content of the node may
generally be unreliable.

I'd recommend:

     generate-id() != generate-id((//h2)[1])

Even this may cause HUGE inefficiency, therefore it is better to
evaluate (//h2)[1] once and define an xsl:variable having this value:

     <xsl:variable name="h2ID" select="generate-id((//h2)[1] )"/>


then at the place, where the test is necessary, have:

     generate-id() != $h2ID
