cool!

I like very much this implementation, it's much much more efficient than mine
and prevents the stack overflow that may happen with long input strings.

Thanks a lot!

I think this does what you want, though I didn't try all your test data.
It's not recursive - if that makes any difference.

<xsl:template name="or">
        <xsl:param name="operand1" select="''"/>
        <xsl:param name="operand2" select="''"/>
        <xsl:variable name="result1">
                <!-- would just return this if we didn't need to do the zero
padding -->
                <xsl:value-of select="translate(string(number($operand1) +
number($operand2)), '2', '1')"/>
        </xsl:variable>
        <xsl:choose>
                <xsl:when test="string-length($operand1) >
string-length($operand2)">
                        <xsl:value-of
select="concat(substring($operand1,1,(string-length($operand1) -
string-length($result1))),$result1)"/>
                </xsl:when>
                <xsl:otherwise>
                        <xsl:value-of
select="concat(substring($operand2,1,(string-length($operand2) -
string-length($result1))),$result1)"/>
                </xsl:otherwise>
        </xsl:choose>
</xsl:template>

With some thought the xsl:choose could probable be improved.

HTH
