Count the number of segments used in payload.

Question

Hi experts,
We have a received payload like :
Seg1 - header
seg2 - item
seg2 - item
seg2 - item
seg3 - footer
In the seg3 footer filed1 should have the value of number of segments used in payload,
for example in above payload the value of field1 should be 5.
How we can count these segments and place the value in field1 of seg3, in our receiver payload ?
Please help.

Hi,
if you want you could try this xslt mapping:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:template match="/">
    <xsl:apply-templates/>
  </xsl:template>
  <xsl:template match="seg3">
    <xsl:copy>
      <xsl:element name="field1">
        <xsl:value-of select="count(//seg2)"/>
      </xsl:element>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>
I have try with this similar xml as source:
<?xml version="1.0" encoding="UTF-8"?>
<segments>
  <seg1>header</seg1>
  <seg2>item1</seg2>
  <seg2>item2</seg2>
  <seg2>item3</seg2>
  <seg3>footer</seg3>
</segments>
And the result was:
<?xml version="1.0" encoding="UTF-8"?>
<segments>
  <seg1>header</seg1>
  <seg2>item1</seg2>
  <seg2>item2</seg2>
  <seg2>item3</seg2>
  <seg3>
    <field1>3</field1>
  </seg3>
</segments>
Maybe it could be useful for you.
