I agree with your method of integration by parts, so you should end up with . The second function does not have a solution in terms of the elementary functions, but Wolfram tells us that this is the Exponential Integral.
Of course, a series solution could be appropriate...
If there is no other way to approach this problem,like let u=e^x and d[xlnx-x]/dx=lnx.
