I have a list of graphic names, "graphicList". I need to search my file for each item in the graphicList in an entity string. I don't know how to reference each item in the graphicList and search for it.

Code so far:

 Dim Regex = New Regex("<!ENTITY .*?SYSTEM ""<graphicListItem>"" .*?>")
        Dim strMasterDoc = File.ReadAllText(FileLocation)
        Dim rxMatches = Regex.Matches(strMasterDoc)
        Dim entityList As New List(Of String)

        Dim entityFound As MatchCollection = Regex.Matches(strMasterDoc)

        'For each file's multipled image file references
        For Each m As Match In entityFound
            Dim found As Group = m.Groups(1)
