Banging my head trying to parse XML

I am trying to parse an XML in ZOHO CRM.

I was able to add a field for the XML to be uploaded so it can be parsed later

So far I am able to get the file data just fine, and even to get to the important node of the XML (it's embedded with CDATA)

But there are two things I don't know how to do:

1. get values only instead of <key>value</key>

2. how to get a list of values, for instance detalles may contain one or several detalles, so I want to get all of detalles in a collection and parse them in a loop to get the required values.

if(factura.get("Archivo_XML") != null)
{
   file = factura.get("Archivo_XML");
   url = file.toCollection().get("download_Url");
   url = "https://crm.zoho.com" + url;
   file = file.toCollection().get("file_Id");
   // to fetch file from the cloud using invokeUrl task
   fileVariable = invokeurl
   [
        url :"https://www.zohoapis.com/crm/v5/files?id=" + file
        type :GET
        connection:"zoho_crm"
   ];
    //response = fileVariable.getFileContent();
   //response = response.toXmlList();
   //info "response: " + response.executexpath("autorizacion/estado");
   //info "response: " + response.executexpath("autorizacion/numeroAutorizacion");
   startFactura = response.find("<infoFactura>");
   endFactura = response.find("</infoFactura>");
    infoFactura = response.subText(startFactura,endFactura) + "</infoFactura>";

   data = infoTributaria.executexpath("infoFactura");
   info data;
   data = infoTributaria.executexpath("infoFactura/fechaEmision");
   info data;
   data = infoTributaria.executexpath("infoFactura/totalConImpuestos/totalImpuesto");
   info data;

}

This is my current code,

This part:

data = infoTributaria.executexpath("infoFactura/fechaEmision");
info data;

Produces

<fechaEmision>08/09/2023</fechaEmision>
