Parse datagroup values as a list

I have a datagroup which I am testing each element of:

foreach item [class names my-dg] {
     if { [string match -nocase $item $teststring] } {

Unfortunately, if the datagroup elements have asterisks in them your config won't load if mcpd does a forceload or you are updating the software (even though you can enter these entries through the GUI, or through tmsh if they are escaped with a "\").

Anyway, I need to rewrite the rule, so I thought I'd just put all the names as values and have an arbitrary name such as a sequence number.

Can someone suggest a simple way to load the datagroup values as a list, so I can just loop through with a foreach, or some other efficient method of checking each value?

    Use class get. It'll produce a list of the keys and values, or rather a list of lists.

    when HTTP_REQUEST {
    set mylist [class get biglist]

    foreach x $mylist {
        log local0. "[lindex $x 0] : [lindex $x 1]"
    }
}
