Does PowerShell work with XML?

XML is stored as a string in PowerShell. Hence it can work with XML.

For example I have a XML document such as this one:

How do I use this XML document?

Just assign this string to a PowerShell string variable as shown:(note the XML formatting has been changed slightly)
