Get current item when iterating over an array of tags with the same name

Asked on Jan 31, 2024

If I have an number of tags, all with the same name that are not contained in a repeater, I can iterate over them in a Map by using the tag name, but, how do I then specify the current item being iterated if I want the value of it?

e.g. We have a tag of Item which is used several times on various questions.

In the map we have

{
    "Name": "Items",
    "ForEach": "Item",
    "Setter": "array",
    "Attributes": [
        {
            "Name": "Description",
            "Value": "<<Item>>"
        }
    ]
}

The resulting XML from this is

<Items><Description></Description></Items>

How do I get the Description element populated with the contents of the current Item node?

We can’t produce XML output like this…

<?xml version="1.0" encoding="utf-8"?>
<Items>
    <Description>1</Description>
    <Description>2</Description>
    <Description>3</Description>
</Items>

The closest we can get would be this…

<?xml version="1.0" encoding="utf-8"?>
<Items>
  <Item>
    <Description>1</Description>
  </Item>
  <Item>
    <Description>2</Description>
  </Item>
  <Item>
    <Description>3</Description>
  </Item>
</Items>

…which you can generate with this map…

{
  "Name": "Items",
  "Entities": [
    {
      "Name": "Item",
      "ForEach": "Item",
      "Setter": "array",
      "Attributes": [
        {
          "Name": "Description",
          "Value": "<<[This]>>"
        }
      ]
    }
  ]
}

Sure, I left out some of the parent info in the map, so yes we are wrapping in an outer Entities array. But, you answered the question with the «[This]» value which is what I need. Cheers, — Anon
