Actually the first result will be <p>fault/unit=key234HrsWft</p> with
this data.

It's not clear to me where you want to add the quotation marks.

But more importantly, I don't understand why you are using named
templates to produce these values rather than variables. If you wrote

<xsl:variable name="key2">data</xsl:variable>

then the problem would be much easier.

If you can't rewrite the templates as variables, then you can achieve
the same effect by capturing the result of the template in a variable:

<xsl:variable name="key2">
	<xsl:call-template name="key2"/>
</xsl:variable>

And then you can test $key2=''.
