Hello

I am new to xsl/xslt. I have following xml

<response>
   <txn_no>1234</txn_no>
   <amount_to_pay>100</amount_to_pay>
</response>
<response>
   <txn_no>8745</txn_no>
   <amount_to_pay>200</amount_to_pay>
</response>
<response>
   <txn_no>5426</txn_no>
   <amount_to_pay>150</amount_to_pay>
</response>

I need to add the amount_to_pay and show it as grand total. How is this possible in xsl? I tried to assign value to variable but it doesnot allow to change it.

Use

<xsl:value-of select="sum(response/txn_no)"/>

when the context node is the parent of the <response> elements.
