Create feature datasets from group layer name

Is it possible to create feature dataset, based on the name from group layers. I have two separate codes, one for finding out the names of group layers, and other to create feature datasets.

>>> import arcpy
    mxd = arcpy.mapping.MapDocument("CURRENT")
    for lyr in arcpy.mapping.ListLayers(mxd):
    if lyr.isGroupLayer == True:
    if lyr.longName.find('\') == -1:
    print lyr.longName

This is the code for searching the name of datasets, and this is the code to create feature datasets.

>>> arcpy.env.overwriteOutput = True
    fdList  = ["Dataset_A", "Dataset_B", "Dataset_C"]
    folList = ["D:\GIS_TempFolder A", "D:\GIS_Temp\Folder B", "D:\GIS_Temp\Folder C"]
    workRange = range(len(fdList))
    for thisIndex in workRange:
    fd = fdList[thisIndex]
    arcpy.env.workspace = folList[thisIndex]
    arcpy.CreateFeatureDataset_management("D:\GIS_Temp\TEST.gdb", fd, "D:\GIS_Temp\Projection.prj")
    for impFC in arcpy.ListFeatureClasses():
    fcName,fcExt = os.path.splitext(impFC)
    fcName.replace(" ","_")
    arcpy.FeatureClassToFeatureClass_conversion(os.path.join(folList[thisIndex],impFC),os.path.join("D:\GIS_Temp\TEST.gdb",fd),fcName)

Is it possible to merge the two codes, into one, so the name fdList = ["Dataset_A", "Dataset_B", "Dataset_C"], would actually be names returned from the group layers based on the first code? I am trying to merge these two codes, so the searched names would actually be names of datasets.
