Parameters
-ContentSpecifies a string that contains the XML to search. You can also pipe strings to Select-Xml.-LiteralPathSpecifies the paths and file names of the XML files to search. Unlike Path, the value of the LiteralPath parameter is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell PowerShell not to interpret any characters as escape sequences.-NamespaceSpecifies a hash table of the namespaces used in the XML. Use the format@{<namespaceName> = <namespaceValue>}.
When the XML uses the default namespace, which begins with xmlns, use an arbitrary key for the namespace name. You cannot use xmlns. In the XPath statement, prefix each node name with the namespace name and a colon, such as //namespaceName:Node.-PathSpecifies the path and file names of the XML files to search. Wildcard characters are permitted.-XmlSpecifies one or more XML nodes.
An XML document will be processed as a collection of XML nodes. If you pipe an XML document to Select-Xml, each document node will be searched separately as it comes through the pipeline.-XPathSpecifies an XPath search query. The query language is case-sensitive. This parameter is required.
