tinytime | ⏰ A straightforward date and time formatter | Date Time Utils library

This sounds rather like a homework assignment. The answers below treat it as such. In other words, these should help point out some of the issues but readers here shouldn't be doing your homework for you.

• Please review the proper format of the pipeline variable. It's $_ not $
  e.g., $_.Name Google: PowerShell Pipeline Variable

• Review the use of comparison operators. There is no such thing as .eq in PowerShell

• Your XML is malformed so, I'm not sure how this script is even getting past $xmlDocument.Load() The syntax used to load the file looks good and you're on the right track to load property values. Once the XML is well-formed, all you'll need is to use the correct paths to the data.

• You only need to read the XML in one time.

• You don't need to use the pipeline variable with a select statement. Just the property name will suffice.
  e.g., Select-Object Name This will return the value of the Name property

I hope this enough to get you moving again.
