getting reference node value using Jaxp

Hi folks,
          I am getting  reference values  if already that element exists. Here is my xml file.

<SingleAttributeCondition>
 <operator class="com.StringOperator">
        <value>equals</value>
      </operator>
<SingleAttributeCondition>

The reference values is
<SingleAttributeCondition>
<operator class="com.NumericOperator" reference="../../SingleAttributeCondtion/operator"/>
</SingleAttributeCondition>

        I dont want the reference value, I want to display the same operator in the second  xml block also.
How can i retrieve the reference  value??
