Recuperar valores de células de tabelas no campo rich-text

Developers sometimes need to retrieve cell values within a table in a Lotus Notes rich-text field (RTF). The following LotusScript code will display the values in each cell within the body of any Lotus Notes mail document.
GetElementCount is used to count different types of RichTextItems in a field. This example uses the Table type.
Sub Initialize
Dim ws As New NotesUIWorkspace
Dim s As New NotesSession
Dim db As NotesDatabase
Dim dc As NotesDocumentCollection
Dim maildoc As NotesDocument
Dim rtitem As NotesRichTextItem
Dim rtnav As NotesRichTextNavigator


Set db=s.CurrentDatabase
Set dc=db.UnprocessedDocuments

If dc.Count>1 Then
Msgbox "Please select a single document", MB_OK,
"Travel HelpDesk"
Continue=False
End
Else
Set maildoc=dc.GetFirstDocument()
Set rtitem=maildoc.GetFirstItem("Body")
Set rtnav=rtitem.CreateNavigator
count = GetElementCount(rtnav, RTELEM_TYPE_TABLE)
'msg$ = msg$ & "Tables:" & Chr(9) & Chr(9) & count% & Chr(10)
'Messagebox msg$,, maildoc.Subject(0)
If count=0 Then
Messagebox "Body item does not contain a table,",, _
"Error"
Exit Sub
End If

For k=1 To count
If rtnav.FindNthElement(RTELEM_TYPE_TABLE,k) Then
Dim rttab As NotesRichTextTable
Set rttab=rtnav.GetElement
Dim rtrange As NotesRichTextRange
Set rtrange=rtitem.CreateRange
If k=1 Then
Call rtnav.FindFirstElement(RTELEM_TYPE_TABLECELL)
Else
Call rtnav.FindNextElement(RTELEM_TYPE_TABLECELL)
End If

firstFlag = True

For i& = 1 To rttab.RowCount
For j& = 1 To rttab.ColumnCount
If Not firstFlag Then
Call rtnav.FindNextElement(RTELEM_TYPE_TABLECELL)
Else
firstFlag = False
End If
Call rtrange.SetBegin(rtnav)
Messagebox rtrange.TextParagraph,, _
"Row " & i& & _

End If
Next
End If

End Sub

GetElementCount = GetElementCount + 1
