get value of elements in NodeList

I'm a bit confused about some expected behavior regarding NodeLists, and was hoping that someone could point me in the right direction.

So I have a hidden input element whose value attribute holds a json string with a bunch of s3 upload data. It looks like this:

<input 
  name="uppyResult"
  type="hidden"
  value="[
    {
        &quot;successful&quot;:[
            {
            &quot;source&quot;:&quot;Dashboard&quot;,
            &quot;id&quot;:&quot;uppy-screen/shot/2021/07/15/at/4/00/02/pm/png-10-10-1d-1d-10-10-1e-1e-10-1e-image/png-165186-1626390007842&quot;,

When I log document.getElementsByName("uppyResult") to console, it shows up as a NodeList. Which apparently is sort of like an array, but not? The data I need to access in this NodeList takes a click and a scroll to get to - I simply expand the input and scroll to defaultValue.

What I need is access to every successful object in this NodeList. There can be one or many. Note that this one has two.

My last attempt at doing this same thing was botched because I misunderstood what I was trying to do. Though the selected answer did solve the problem as I phrased it, what I needed was to perform the same action for more than just the initial [0] item. Each uploaded batch of files occupies an index in this array, and I need to get all of them.

The old code from that answer is:

if (reason === 'removed-by-user') {
  const preParsedData = document.getElementsByName("uppyResult")[0].value //this is the problem, i think - i need *all* the elements in the array/NodeList
  const parsedData = JSON.parse(preParsedData)
  const toRemove = file.id
  parsedData.forEach(item => {
    Object.values(item).forEach(array => {
      if (!Array.isArray(array))
        return;
      const index = array.findIndex(elm => elm.id === toRemove)
      if (index > -1)
        array.splice(index, 1)
    });
    if (item.successful.length === 0)
      delete item.successful
      delete item.failed
      delete item.uploadID
    });
    console.log(parsedData)
    document.getElementsByName("uppyResult")[0].value = JSON.stringify(parsedData)
  }
})
