in python I would do this:
>>> ss=['&', '-1.878722E-08,', '3.835992E-11','1.192970E-03,-5.080192E-06']
>>> li = []
>>> for j in ss:
for ii in j.split(','): # assumes "," is delimiter
try: li.append(float(ii));
except ValueError: pass
>>> li
[-1.8787219999999999e-008, 3.8359920000000003e-011, 0.00119297,
-5.0801919999999999e-006]
>>> np.array(li)
array([ -1.87872200e-08, 3.83599200e-11, 1.19297000e-03,
-5.08019200e-06])
