Example_CCI_List_Loop.ps1

## Note the snippet is the second part of the script which
## demonstrates extracting information from DISA NIST XML files

## Download and unzip the latest control list 
## from: http://iase.disa.mil/stigs/cci/Pages/index.aspx
$CCIControlFile = '~\Documents\U_CCI_List.xml'

## This is the NIST Revision we are wanting to reference:
$CCIFilter = 'NIST SP 800-53 Revision 4'

## loop through the Stig Collection updating the Control information 
## pulled from the U_CCI_List.xml
foreach($StigObj in $StigCollection){
    foreach($CciItem in $CCIX.cci_list.cci_items.cci_item){
        if($CciItem.Id -EQ $StigObj.ControlIdentifier){
            ## filter the control version by the title
            if($CciItem.references.reference.title -EQ $CCIFilter){
                $StigObj.Control = $CciItem.references.reference.index
            }
        }
    }
