Duplicate instance node to another instance

I have two instance

<model>
  <instance id="instance-1">
    <options>
      <option>
        <id>1</id>
        <name>NAME 1</name>
      </option>
      <option>
        <id>2</id>
        <name>NAME 2</name>
      </option>
      <option>
        <id>3</id>
        <name>NAME 3</name>
      </option>
      <option>
        <id>4</id>
        <name>NAME 4</name>
      </option>
    </options>
  </instance>
  <instance id="instance-2">
    <items>
      <item>
        <options>
          <option>
            <id />
            <name />
          </option>
        </options>
      <item>
    </items>
  </instance>
</model>

I would like to copy instance-1 all option to instance-2 when particular
event activated, like this

  <instance id="instance-2">
    <items>
      <item>
        <options>
          <option>
            <id>1</id>
            <name>NAME 1</name>
          </option>
          <option>
            <id>2</id>
            <name>NAME 2</name>
          </option>
          <option>
            <id>3</id>
            <name>NAME 3</name>
          </option>
          <option>
            <id>4</id>
            <name>NAME 4</name>
          </option>
        </options>
      <item>
    </items>
  </instance>

How to accomplish it?

thanks in advance,

Jack

you will have to use xforms:insert / xforms:setvalue for every element
to copy - to iterate over the option elements, you could use xxform:iterate:

Iterating may not be needed in this case:

<xforms:delete nodeset="instance('instance-2')/items/options/option"/>
<xforms:insert context="instance('instance-2')/items/options"  
origin="instance('instance-1')/option"/>
