连续将XML导入Powershell脚本

Question

I have a project to create a script to handle our Lync provisioning - trying to keep it as modular as possible. I think this works best by keeping each script file in its own directory, with its own 'scopedConfig' & a 'centralXML' with tags that are globally useful.

The problem I have is when trying to import 2 XML files consecutively using Get-content.

The code I have is:

# Import CentralConfig
[xml]$centralXML = Get-content ".\centralConfig.xml"

# Import ScopedConfig
[xml]$scopedXML = Get-content ".\ExecutionResources\ScopedConfigfiles\HostConsole\config.xml"

I'm testing successful import with the following:

"------------------"
"------------------"
$centralXML
"------------------"
$scopedXML
"------------------"
"------------------"

The result and where the issue lies is the output:

------------------
------------------
Global_ConfigRoot
-----------------
Global_ConfigRoot
------------------

------------------
------------------

I expected the root nodes of both XMLs as output, instead I only get the root node of the first. If I swap it round so that $scopedXML is first - I only get $scopedXML root node and nothing from $centralXML.

An interesting thing to note is that if I pipe the 2nd XML to Get-member - where you'd usually expect to see all XML related things and it's properties, I get a whole load of blankness:

------------------
------------------
Global_ConfigRoot
-----------------
Global_ConfigRoot
------------------

I have never come across this before, does anyone have any suggestions?

A function, cmdlet or script can only return AN object. It you return mulitple like you do by calling both variables, it actually returns an object[] array containing both items (+ the lines you printed). The objects are untouched and just added to this collection.

Now, when your script outputs(displays) the object that was returned, it formats it as a table since there were multiple objects inside. A table can only contain 1 header(column-names), and when displaying an array, it takes the columns(properties) from the first item, in this case $centralxml . That's why you get 2 columns: xml and servers.

If you want to seperate them you have to tell the script to format them in seperate tables. Ex:

# Import CentralConfig
[xml]$centralXML = Get-content ".\test.xml"

# Import ScopedConfig
[xml]$scopedXML = Get-content ".\test2.xml"

$centralXML | Format-Table
$scopedXML | Format-Table
