Can this be achieved in xslt 1.0?
You just repeated your initial question.
XSLt doesn't have "inout variables" and "output variables" I'm guessing
that you mean, respectively, parameters and variables, but it's hard to
be sure.
variables always have a value if declared so you need to say what value
you want for each of your three variables.
I'm guessing that you want, for variable3 something like the first of
input3,input2,input1 that is not empty.
In XSLT2 that would be
<xsl:variable name="variable3"
select="($var3,$var2,$var1)[not(.='')][1]"/>
on xslt1 if you could use
<xsl:variable name="variable3" >
<xsl:choose>
<xsl:when test=not($var3='')"><xsl:value-of select="$var3"/></xsl:when>
<xsl:when test=not($var2='')"><xsl:value-of select="$var2"/></xsl:when>
<xsl:otherwise><xsl:value-of select="$var1"/></xsl:otherwise>
</xsl:choose>
</xsl:variable>
