add a new node to xml data

Question

Hi All,

My xml file is like this:

<?xml version="1.0" encoding="ISO-8859-1"?>

 - <note>

    <step ID="1">

       <to><to1>Tove<to1></to>

       <from>Jani</from>  

    </step>     

    <step ID="2">

        <to><to1>Tove1<to1></to>

       <from>Jani1</from>

  </step> 

 <step ID="3">

        <to><to1>Tove2<to1></to>

       <from>Jani2</from>

 </step> 

</note>

I want to add a new node (<check>ok</check>) to where ID= 2

my xpath is: note/step[ID='2']/to/

final result should be like this in xml file:

 <step ID="2">

        <to>

           <to1>Tove1<to1>

           <check>ok</check>

       </to>

       <from>Jani1</from>

 </step> 


Thanks
