I wanted to automate the process of creating a new package. The following code will look at an XML file for values (same xml file I am using here) and create a package based on the values. A lot of SCCM PowerShell was gathered from here. Here is the example of the source XML file:

<Install>
<Params>
<PkgName Value="Firefox" />
<PkgManufacturer Value="Mozilla" />
<PkgVersion Value="12.0" />
<PkgSourcePath Value="\\domain.local\DFSRoot\Path\Mozilla\Firefox-12.0" />
<PkgcontainerNodeID Value="17" />
<CurrentVersionQueryName Value="Software-MozillaFirefox-12.0" />
<OtherThanQueryName Value="Software-MozillaFirefox-OtherThan-12.0" />
<QuerycontainerNodeID Value="4" />
</Params>
</Install>

And here is the script that creates the package, program, distribution point,and 2 queries (A query to show where version is installed, and a second to show where it is not installed (NOT IN).)

function JBMMURPHY-SCCM-CreatePackageAndQueries{
PARAM(
    [Parameter(Mandatory=$true)]
    [ValidateScript({Test-Path $_})]
    $XMLFilePath)
[ xml ]$s = Get-Content $XMLFilePath
