Use of following to get unique nodes???

[johkar]

In the below example I am using the following to try to match only the
unique MechanismText nodes within each Subscription node:

select="Deliver yPreferences/DeliveryPrefere nce[not(MechanismTe xt=following::
MechanismText)]"
Right now, the 2nd select populates correctly, but the 1st select is empty.
I know what is going on, but I don't know how to correct it.

I would appreciate any ideas, solutions or pointers you can give me.

Thanks, John

After the transformation, I should have two select lists...one for each
Subscription node.

1st Select:
<select>
<option>Email </option>
<option>Fax</option>
</select>

2nd Select:
<select>
<option>Email </option>
<option>Fax</option>
</select>
XSL TEMPLATES
<xsl:template mode="standard"
match="/myRoot/Response/Subscriptions/Subscription">
<select>
<xsl:apply-templates mode="optionbui lder"
select="Deliver yPreferences/DeliveryPrefere nce[not(MechanismTe xt=following::
MechanismText)]" />
</select>
</xsl:template>

<xsl:template mode="optionbui lder"
match="Delivery Preferences/DeliveryPrefere nce[not(MechanismTe xt=following::M
echanismText)]">
<xsl:element name="option">
<xsl:choose>
<xsl:when test="..//UserPreferenceF lag = 'Y'">
<xsl:if test="UserPrefe renceFlag = 'Y'">
<xsl:attribut e name="selected" >selected</xsl:attribute>
</xsl:if>
</xsl:when>
<xsl:otherwis e>
<xsl:if test="DefaultPr eferenceFlag = 'Y'">
<xsl:attribut e name="selected" >selected</xsl:attribute>
</xsl:if>
</xsl:otherwise>
</xsl:choose>
<xsl:attribut e name="value"><x sl:value-of
select="Mechani smCode"/></xsl:attribute>
<xsl:if test="Mechanism Text != 'NONE'">
<xsl:value-of select="Mechani smText"/>
</xsl:if>
</xsl:element>
</xsl:template>
