TODO: repackage the xml object into intended powershell objects Output types: -xCATData -xCATNodeData -xCATNoderangeData xCAT Data has error and data not contained within a node xCATNodeData has error and data contained within a node xCATNoderangeData will be an aggregation of the above (to be treated differently ps1xml wise hopefully) The original noderange will be chucked into any of these, for Merge-xCATNodeData to have as a hint maybe git-svn-id: https://svn.code.sf.net/p/xcat/code/xcat-core/branches/2.8@15646 8638fb3e-16cb-4fca-ae20-7b5d299a9bcd
