NAME Test-NodeExists



SYNOPSIS

Tests if a node exists in an XML document.





SYNTAX

Test-NodeExists [-Xml] <XmlDocument> [-XPath] <String> [[-DefaultNamespacePrefix] <String>] [<CommonParameters>]





DESCRIPTION

It's usually pretty easy in PowerShell to check if a node exists in an XML document: simply test if a property

exists on that node. If, however, that XML document has namespaces, you have to do extra setup with the XML

document so that you can find the node. This function does that work for you.
