Sorting on one attribute removes another attribute from xml file

I want sort the xml data based on count attribute and select first 100 values.

I have written this xsl. But it is removing @code from indicator tag which is required for further processing.

<xsl:template match="node()|@*">
                   <xsl:if test="//field[count(indicators/indicator/values) &lt; '100' or count(subfields/subfield/position/values) &lt; '100']">
     <xsl:copy>

         <xsl:apply-templates select="node()|@*">
            <xsl:sort select="@count" data-type="number" order="descending"/>
    </xsl:apply-templates>

     </xsl:copy>
               </xsl:if>
    </xsl:template>

The xml data is :

<field count="3159" tag="461">
      <indicators>
        <indicator code="1">
          <values count="3159" value=" " />
        </indicator>
        <indicator code="2">
          <values count="3159" value="1" />
        </indicator>
      </indicators>
      <subfields>
        <subfield code="3" count="3497">
      <position>
        <values count="1" value="200000000120020805151840" />
        <values count="28" value="200000000220020805151840" />
        <values count="32" value="200000190420020805152452" />
        <values count="8" value="200000190520020805152453" />
        <values count="1" value="200000190620020805152453" />
        <values count="9" value="200000190720020805152453" />
        <values count="6" value="200000190820020805152454" />
        <values count="3" value="200000190920020805152454" />
      </position>
    </subfield>
      </subfields>
    </field>

Please help to find 100 highest values and @code attribute which is removed after sorting from indicator tag.
