How to add list of Nodes in existing Node Xml in groovy

Question

I have such a XML structure, with list of 'attachments', and I want iterate incoming List files and create a groovy.util.Node for each of them and then return the builded Node. In code below I use only the fist element from list(base64 file), but I want to create attachments dynamically based on array size. I am new in groovy and can't find the way how to expand the Node properly.

import groovy.abi.XML

class TestService {
    
    Node buildNode(List files) {
        Node node = XML.builder().
            "sab:sendExternalEmail"("xmlns:sab": "http://sab/") {
                "sab:to"('client@gmail.com')
                "sab:subject"('Reply')
                "sab:body"('Body')
                "sab:from"('sender@gmail.com')
                "sab:attachments"() {
                    "sab:attachment"() {
                        "sab:fileName"('file1')
                        "sab:fileBase64"(files[0])
                    }
                }
            }
    }
}

just to give you an idea how to work with builders:

import groovy.util.NodeBuilder
import groovy.xml.XmlUtil


def attachments = [
    "name 1": "content 1",
    "name 2.txt": "content 2"
]

def xml = new NodeBuilder().a{
  for(a in attachments){
    attacchment{
      fileName(a.key)
      fileBase64(a.value)
    }
  }
}

println XmlUtil.serialize(xml)

result:


  
    name 1
    content 1
  
  
    name 2.txt
    content 2
