<xsl:variable name="from">
          <xsl:choose>
             <xsl:when test="../parent='Field'">53</xsl:when>

You want
               <xsl:when test="parent::Field">53</xsl:when>

             <xsl:when test="../parent='AutoEnter'">54</xsl:when>
             <xsl:when test="../parent='Validation'">55</xsl:when>
          </xsl:choose>
       </xsl:variable>
