What are you actually trying to achieve? If you simply want to test whether
one of the elementA elements contains "1234", you can write

<xsl:if test="elements/elementA[contains(., '1234')]">
   ...
</xsl:if>

But I can't tell if that's what you are trying to do because you don't say.
You've been using this list long enough to know that most of us have
difficulty reverse-engineering requirements from non-working code.
