Excel VBA identify onmouseover value in web page table

[FractalWalk]

I am scraping data from a web page HTMLtable using Excel 2010 VBA and have succesfully captured all of the table cell values. However, for one of the cells, the value is a partial string of the data I need. The actual value is contained in the onmouseover property/event. In other words the web page displays "ABC..." in the cell and I capture that, but when you place the cursor over that cell a tooltip appears showing the full value of "ABCDEFG".

So my question is how can I extract that onmouseover value. I can easily identify the cell in the table, but is there some property I can use to find that value? I tried .onmouseover, but the value returned is null. To complicate matters, the table is created via a script so I can't see it in the source html. I tired listing all of the innertext on every element of the page, but there was no onmouseover listed.

Here is the relevant portion of my code:

        Set iedoc = IE.Document
        For i = 0 To iedoc.all.Length - 1        
            If TypeName(iedoc.all(i)) = "HTMLTable" Then
                Set IeTable = iedoc.all(i)
                For x = 1 To IeTable.Rows.Length -1
                    For p = 0 To IeTable.Rows(x).Cells.Length - 1
                        Set iecell = IeTable.Rows(x).Cells(p)
                        txt = Trim(iecell.innertext)
                        if p = 2 then
                           txt = 'This is where I would want to identify the value from the onmouseover
                        Endif
                    Next p
                Next x
            End If
        Next i
