I would like to process my XML document in a subseted, user driven mode. =
 Given the following raw data
<data>
<record id=3D"1"><field1>field 1</field1><field2>field =
2</field2><field3> field 3</field3><field4> field 4</field4></record>
<record id=3D"2"><field1> field 1</field1><field2> field =
2</field2><field3> field 3</field3><field4> field 4</field4></record>
</data>

I would like to define a user "view" as such (format of next snippet is =
open to change)
<displayorder>
<field>field3</field>
<field>field2</field>
</displayorder>
which would extract only fields 3 and 2 and in that order vs document =
order.

Here are my attempts.
  <xsl:template match=3D"record">
    <TR><TD nowrap=3D"yes">record id=3D<xsl:value-of =
select=3D"@id"/></TD></TR>
    <TR><TD nowrap=3D"yes">brute force method</TD>
    <xsl:apply-templates =
select=3D"*[local-name()=3Dxt:node-set(document($customFile)/displayorder=
/field)[1]]"/>
    <xsl:apply-templates =
select=3D"*[local-name()=3Dxt:node-set(document($customFile)/displayorder=
/field)[2]]"/>
    <xsl:apply-templates =
select=3D"*[local-name()=3Dxt:node-set(document($customFile)/displayorder=
/field)[3]]"/>
    </TR>
    <TR><TD nowrap=3D"yes">subseted but in document order</TD>
    <xsl:apply-templates =
select=3D"*[local-name()=3Dxt:node-set(document($customFile)/displayorder=
/field)]"/>
    </TR>
    <TR><TD nowrap=3D"yes">not working at all</TD>
    <xsl:for-each =
select=3D"xt:node-set(document($customFile)/displayorder/field)">
need help here.  I have trouble getting to the proper context
    </xsl:for-each>
    </TR>
   </xsl:template>
  <xsl:template match=3D"record/*">
    <TD nowrap=3D"yes"><xsl:value-of select=3D"."/></TD>
  </xsl:template>
=20
Next would be to make fewer calls to document !
TIA,
