Hello, everybody!

I have adapted a script that changes the data sources of the layers in one mxd provided by user input.
All I want is to have this script accept multiple mxds from user and loop through the script.
I know this situations has been described before, however I was not able to implement the advice found here.
I am at the very beginning of my python experience, therefore any help on this would be much, much appreciated.
I paste in the code with my trial for multiple mxd input:

import arcpy

#set new SDE connection
newSdePath = r"Database Connections\myConnection.sde"

#get mxds  as input from user
mxdAr = arcpy.GetParameterAsText(0)
mxd = arcpy.mapping.MapDocument(mxdAr)

#parse through the list of mxds, dataframes, layers; change data sources

for mxdItem in mxd.split(";"):
        for df in arcpy.mapping.ListDataFrames(mxd):
                for lyr in arcpy.mapping.ListLayers(mxd, ""):
                        if lyr.isFeatureLayer== True:
                             lyr.replaceDataSource(newSdePath, "SDE_WORKSPACE","", False)
del mxd

The error i get :
File "D:\Program Files (x86)\ArcGIS\Desktop10.1\arcpy\arcpy\arcobjects\", line 608, in __init__
    assert (os.path.isfile(mxd) or (mxd.lower() == "current")), gp.getIDMessage(89004, "Invalid MXD filename")
AssertionError: Invalid MXD filename.

Thank you for your help!
