How to extract values from a xml request body with values in an array in wiremock

Question

I am trying to extract line-item value from the below request body into my response in wiremock.

Request:

**<request>
 <lineItem>
   <item> 
        <name> name </name>
        <quantity> 12 </quantity>
        <type>type</type>
</item>
</ lineItem>
<lineItem>
   <item> 
        <name> name2 </name>
        <quantity> 10 </quantity>
        <type>type2</type>
</item>
</ lineItem>
</request>**

Expected Response:

**<response>
 <lineItem>
   <item> 
        <name> name </name>
        <quantity> 12 </quantity>
        <type>type</type>
</item>
</ lineItem>
<lineItem>
   <item> 
        <name> name2 </name>
        <quantity> 10 </quantity>
        <type>type2</type>
</item>
</ lineItem>
</response>**

I tried something like this:

    <response>
    {{#each (xPath request.body '/lineItem/item ') as |element| }}
     <lineItem>
       <item>  
       <quantity>  (xPath request.body '//lineItem/item/quantity/text()'}}</quantity>  
    </item>
    </ lineItem>
    </response>

but for 2 different lineItem in request (as given above), I got 3 lineItem values in response and always getting the first item values in all the 3 lineItems:

Response I got:

**<response>
 <lineItem>
   <item> 
        <quantity> 12 </quantity>
</item>
</ lineItem>
<lineItem>
   <item> 
        <quantity> 12 </quantity>
</item>
</ lineItem>
<lineItem>
   <item> 
        <quantity> 12 </quantity>
</item>
</ lineItem>
</response>**

Can someone help me with this scenario?

I ran into a similar problem today. I also needed to get a list of values from a request and create in response as many objects based on this as I received.
If we shift the solution to your question, then it will looks like this:

<response>
  {{#each (xPath request.body '//lineItem/item/quantity') as |element| }}
  <lineItem>
     <item>  
       <quantity>{{element.text}}</quantity>  
     </item>
  </lineItem>
  {{/each}}
</response>
