Question

I am newbie in XSLT.I am Using XSLT(XML to XML).Please check my code –

Input XML –

 <FCRep>
      <AirInfo>
          <AdtTransFee>0.000</AdtTransFee>
          <ChdTransFee>0.000</ChdTransFee>
          <InfTransFee>0.000</InfTransFee>
          <AutoCharges grandTotal="30.000">
            <Charge name="SAFI" operator="+" isSupplierFee="TRUE" ApplyOn="BaseFare">
              <Adult>5.000</Adult>
              <Child>5.000</Child>
              <Infant>5.000</Infant>
              <DBAmount type="fixed" />
              <Total>15.000</Total>
            </Charge>
            <Charge name="APC" operator="+" isSupplierFee="TRUE" ApplyOn="BaseFare">

          </FareDetails>

    </FlightDetailRule>

My output is coming fine but I also want ChgTotal attribute in OthChg nodes.
Please suggest me that how I can do this.

Thanks in advance.

It is appropriate here to use the standard XPath function sum() like this:

Your code:

              <xsl:element name="OthChg">
                <xsl:attribute name="ChgTotal">
                </xsl:attribute>
                <xsl:for-each select="AutoCharges/Charge">
                  <xsl:element name="Chg">
                    <xsl:attribute name="NM">
                      <xsl:value-of select="@name"/>
                    </xsl:attribute>
                    <xsl:value-of select="Adult"/>
                  </xsl:element>
                </xsl:for-each>
                <xsl:element name="Chg">
                  <xsl:attribute name="NM">
                    <xsl:value-of select="'TransFee'"/>
                  </xsl:attribute>
                  <xsl:value-of select="AdtTransFee"/>
                </xsl:element>
              </xsl:element>
            </xsl:element>

Correct code:

            <OthChg ChgTotal="{sum(AutoCharges/Charge/Adult)+AdtTransFee}">
                <xsl:for-each select="AutoCharges/Charge">
                  <Chg NM="{@name}">
                    <xsl:value-of select="Adult"/>
                  </Chg>
                </xsl:for-each>
                <Chg NM="TransFee">
                  <xsl:value-of select="AdtTransFee"/>
                </xsl:element>
            </OthChg>
