xsl grouping tags into parent

my xml is :

<Row>
    <one>1</one>
    <two>2</two>
</Row>

and My expected result is :

 <main>
        <value type="one_type">
          <stringValue>1</stringValue>
        </value>
        <value type="two_type">
          <stringValue>2</stringValue>
        </value>
  </main>

and my xsl is :

<xsl:template match="node()|@*">
        <xsl:copy>
            <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>
    </xsl:template>


    <xsl:template match="one|two">
    <main>
        <xsl:choose>
            <xsl:when test="one">
                <value type="one_type">
                    <stringValue>
                        <xsl:apply-templates select="@*|node()"/>
                    </stringValue>
                </value> 
            </xsl:when>
            <xsl:otherwise>
                <value type="two_type">
                    <stringValue>
                        <xsl:apply-templates select="@*|node()"/>
                    </stringValue>
                </value> 
            </xsl:otherwise>
        </xsl:choose>
    </main>

    </xsl:template>

But this returns two different main tags and I want all the tags to be under the main tag. Any Idea how to do this ? i thought if else will give me the desired result but it does not.
