Syntax

Read-XmlNode [-NodeType] <String> [-Path] <String> [-XPathQuery] <String> [-ContinueOnError] [-Wow64] [[-Attribute] <String>] [[-Index] <Int32>] [-ResultVariable] <String> [[-IndexVariable] <String>] [[-HintPath] <String>] [[-Context] <String>] [<CommonParameters>]

Description

Use this command to read information from existing XML files. In the dialog box you can specify the information you want to read from a specific XML file (Element, Attribute, Contents). If there are several matches for the part of the XML file you want to read, you can use an index to specify the match exactly.

-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

Accepts pipeline input

False

-IndexVariable <String>

Specifies the variable where you want to store the index of the used match without %. You can use this variable to determine the maximum value for the query loop. In this case we recommend that you enter the Read-XmlNode command several times in the eScript: first, to determine the maximum index and second to read the individual values in a corresponding loop.

Required

False

6

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.

-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

Named

-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.
