ImportXML called 3 times

Slight problem with Application.ImportXML. When I run this command in VBA so that it gets the XML from a webpage I noticed it calls the page 3 times. Does anyone know why this happens?

My call is:


Private Sub SendMessage()
Dim MyXMLURL As String
MyXMLURL = "URL"

Application.ImportXML _
DataSource:=MyXMLURL, _
ImportOptions:=acStructureAndData

End Sub


I've set the php file to write to a text file each time it loads and you can see for yourselves that it writes to the file 3 times
