HTML object library/ WebBrowser object

I'm writing a function to scan through an HTML document object, and find an element based on the arguments being passed in.

Public Function GetHTMLElement(htmlDocument as HTMLDocument,  sElementName as String, Optional sElementType as String)

Dim oElement as HTMLhtmlElement
Dim i as Integer

If sElementType <> "" then
For Each oElement in htmlDocument.getElementsByTagName
???
Next oElement
End If

For i = 1 To htmlDocument.Frames.length
     ? = GetHTMLelement(htmlDocument.Frames(i).Document, "string", "string2")
next i

End function


This is all I have so far.  I'm interested in returning a collection of elements that match arg2 and arg3.  How do I populate this function with each element that matches the criteria?  Thanks for any commets/suggestions.

Try this...


Public Static Function GetHTMLElements(htmlDocument As Object, Optional sElementTagName As String, Optional sElementAttribute As String, Optional sElementName As String, Optional NewCall As Boolean = True) As Collection
Dim oElement As HTMLHtmlElement
Dim i As Integer
Dim o As Object
Static x As Collection

If NewCall Then Set x = New Collection
Set GetHTMLElements = New Collection

If sElementTagName <> "" Then
    If sElementAttribute <> "" Then
        For Each oElement In htmlDocument.getElementsByTagName(sElementTagName)
            If UCase(oElement.Attributes(sElementAttribute)) = UCase(sElementName) Then
                x.Add oElement
            End If
        Next oElement
    Else
        For Each oElement In htmlDocument.getElementsByTagName(sElementTagName)
            x.Add oElement
        Next oElement
    End If
Else
    For Each oElement In htmlDocument.All
        x.Add oElement
    Next oElement
End If

If htmlDocument.frames.length > 0 Then
    For i = 0 To htmlDocument.frames.length - 1
        Set o = htmlDocument.frames(i).document
        GetHTMLElements o, sElementTagName, sElementAttribute, sElementName, False
    Next i
End If
Set GetHTMLElements = x

End Function

Azra-

That works for one document, but if a particular webpage contains x frames, that means x document objects.  I want this function to keep calling itself until it has looped through all subframes and at the same time populating the collection the function is defined as.

Public Function GetHTMLElement(htmlDocument as HTMLDocument,  sElementName as String, Optional sElementType
as String) as Collection

Dim oElement as HTMLhtmlElement
Dim i as Integer

If sElementType <> "" then
For Each oElement in htmlDocument.getElementsByTagName
???
Next oElement
End If

For i = 1 To htmlDocument.Frames.length
    ? Set GetHTMLelement = GetHTMLelement(htmlDocument.Frames(i).Document, "string", "string2") 'i get a type mismatch here
next i

End function

try:
GetHTMLElement(htmlDocument.Frames.Item(i).Document, "string", "string2")
