Test-XmlNode

Synopsis

The value exists in an XML file

Syntax

Test-XmlNode [-NodeType] <String> [-Path] <String> [-XPathQuery] <String> [-ContinueOnError] [-Wow64] [[-Attribute] <String>] [[-Index] <Int32>] [[-Content] <String>] [[-HintPath] <String>] [[-Context] <String>] [<CommonParameters>]

Description

Checks if a value exists in a specific XML file. Apart from specifying the actual XML file, you also have to specify which entry you want to check in the XML file. For this reason, specify the entry type and an XPath query. This query works like the Read-XmlNode command. In addition, you must specify the search string. The wildcards * and ? can be used. If you leave the field empty, the system checks for empty contents.

Parameters

-Attribute <String>

This entry provides the name of the queried attribute if you select Entry type = Attribute. You are allowed to use the * wild card.

-Context <String>

User: Execution under user account; logging in HKEY_CURRENT_USER, i.e. for the user.
UserPerService: User-related command, execution in Service context.
Computer: Execution under user account; logging in HKEY_CURRENT_MACHINE, i.e. for the computer.
ComputerPerService: Execution in service context; logging in HKEY_LOCAL_MACHINE, i.e. for the computer.

-ContinueOnError <SwitchParameter>

Continues script execution in spite of errors in the respective command

Required	False
Position	Named
Accepts pipeline input	False

-HintPath <String>

#TODO#

Required	False
Position	6
Accepts pipeline input	False

-Index <Int32>

The index determines which element is to be read if the query finds several matches in the XML file. The following options are available: First match(default), Last match, Specific Index. Specify the location of the specific element on the match list, for example 3 for the third incidence in the XML file.

Required	False
Position	4
Accepts pipeline input	False

-NodeType <String>

Select the type of the part of the XML file you want to read:
Element - Basic structural unit of an XML file that usually has a tag at the beginning and the end.
If you search for an element, the result variable contains the complete element with beginning and end tag and the complete contents between the tags. Searching for an element returns the complete element, for example: <Object type="STRING">QueenMary</Object>.
Attribute of an element
If you search for an attribute, the result variable returns the value of the attribute. Searching for the attribute type in the above example element results in: STRING.
Contents of an element
If you search for the contents, the result variable contains the complete text contents of the searched element between the beginning and the end tag. This does not include subelements with their text contents. Searching for the contents in the above example element results in: QueenMary.

Required	True
Position	0
Accepts pipeline input	False

-Path <String>

Path and name of the XML file you want to read. If not specified, the extension .XML is used automatically.

Required	True
Position	1
Accepts pipeline input	False

-Wow64 <SwitchParameter>

By default, the PackageDeployment module assumes to run in a 64-bit PowerShell process on 64-bit systems, and therefore defaults to the 64-bit application location (if different from the 32-bit application location) for file and registry accesses. If you want to access the 32-bit counterparts (in the file system %WinDir%\SysWOW64 instead of %WinDir%\System32, in the registry HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node instead of HKEY_LOCAL_MACHINE\SOFTWARE), use the -Wow64 switch.

Required	False
Position	Named
Accepts pipeline input	False

-XPathQuery <String>

Used to identify the part of the XML file you want to read with the help of the XPath syntax. XPath query example: //Sample/node1/node2/Object[@type="STRING"]. In this example, the system queries the Object element in Sample/node1/node2 to which the type="STRING" applies. In most cases, the system finds several elements that match the query; therefore, specify an Index in addition.

Required	True
Position	2
Accepts pipeline input	False
