Search File for string containing list items

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:

Code:

---

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)
            entityList.Add(found.Value)
        Next

---

Code:

---

dim list as new List(Of String)
list.add("one")
list.add("two")
list.add("three")

dim regString as String = "(" & String.Join("|", list.toarray) & ")"

---

Then in your regex replace graphicListItem with regString

Just one small note: String.Join has accepted any IEnumerable(Of T) for some time now, so the ToArray call is most likely not necessary. Does no real harm but does no real good either.
