[xsl] Testing for parent node

Hi everyone,

I am on this list but I rarely post.

               <Field id="1" dataType="Text" fieldType="Normal" name="name">
                  <Comment/>
                  <AutoEnter allowEditing="True" constant="False" 
furigana="False" lookup="False" calculation="False">
                     <ConstantData/>
                  </AutoEnter>
                  <Validation message="False" maxLength="False" 
valuelist="False" calculation="False" alwaysValidateCalculation="False" 
type="OnlyDuringDataEntry">

                     <Existing value="False"/>
                     <StrictValidation value="False"/>
                  </Validation>
                  <Storage autoIndex="True" index="None" 
indexLanguage="English" global="False" maxRepetition="1"/>
               </Field>

My XPATH is fixed to all Calculations within the BaseTableCatalog - like this.

/FMPReport/File[1]/BaseTableCatalog[1]//Calculation

In some cases the parent of the calculation will be "Field" (see example) in 
other cases it will be "AutoEnter" (see example) or "Validation"

I have tried a number of different things but I can't get any of them to work 
and bring me reliable results.

This returns nothing for the"$from" variable

      <xsl:variable name="from">
         <xsl:choose>
            <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>

This returns nothing when the calculation is a child of Field but it returns 
always the 53 when the calculation is "AutoEnter" or "Validation"

      <xsl:variable name="from">
         <xsl:choose>
            <xsl:when test="local-name(../parent::*)='Field'">53</xsl:when>
            <xsl:when test="local-name(../parent::*)='AutoEnter'">54</xsl:when>
            <xsl:when test="local-name(../parent::*)='Validation'">55</xsl:when>
         </xsl:choose>
      </xsl:variable>

I know the answer is obvious and I am just missing it.

Thanks for any suggestions or help on this.

Vince
