Question

for example below is the xml

<products>
    <product>
        <name>Pen</name>
        <Quantity>2</Quantity>
        <Amount><Price>2</Price><Currency>USD</Currency></Amount>
    </product> 
    <product>
        <name>Pencil</name>
        <Quantity>20</Quantity>
        <Amount><Price>2</Price><Currency>USD</Currency></Amount>
    </product>
    <product>
        <name>Bag</name>
        <Quantity>25</Quantity>
        <Amount><Price>2</Price><Currency>USD</Currency></Amount>
    </product>
</products>

in my xsl i using like below to remove

<xsl:copy-of select="node()[not(self::Quantity)]"/>

I also need to remove sub node <Currency> from the <Amount>

i try like below

<xsl:copy-of select="node()[not(self::Quantity) and not(self::Amount/Currency)]"/>

but not working fine . it will remove all node’s from <Amount>

How i remove sub node <Currency> only?

If you really want to use self

    <xsl:template match="@* | node()">
        <xsl:copy>
            <xsl:apply-templates select="@* | node()"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="node()[self::Currency]"/>

or if you want to know other simpler way 🙂

    <xsl:template match="@* | node()">
        <xsl:copy>
            <xsl:apply-templates select="@* | node()"/>
        </xsl:copy>
    </xsl:template>
  <xsl:template match="Currency"/>

The above templates copy all other tags except <Currency>

EDIT: Replace the below code

<xsl:template match="product">
   <product>
    <xsl:for-each select="key('kProdByName', name)">
      <xsl:if test="position() = 1">
        <xsl:copy-of select="node()"/>
      </xsl:if>
    </xsl:for-each>
   </product>
</xsl:template>

By this: (hope it works)

  <xsl:template match="product">
    <product>
      <xsl:for-each select="key('kProdByName', name)">
        <xsl:if test="position() = 1">
          <xsl:apply-templates select="node()|@*"/>
      </xsl:if>
      </xsl:for-each>
    </product>
  </xsl:template>

  <xsl:template match="Currency|Quantity"/>
