Question:
I’m writing a script that is supposed to look at the content of a file and determine if it is a (well formed) XML or not. I found a page on [ss64.com][1] that this is quite easy to do:
|
1 2 3 |
>32 -is [int] True |
The thing is however that I can only test this by casting the left-side for XML files:
|
1 2 3 |
>[xml](Get-Content c:\Path\To\xml_file.xml) -is [xml] False |
…which in this case would be rather pointless: if the file is XML, the casting will already prove this, else throw an exception. I therefore wonder: is there any way to determine XML files in Powershell in a True-False way?
Answer:
Try the -as operator:
|
1 2 |
[bool]((Get-Content c:\Path\To\xml_file.xml) -as [xml]) |
