$\displaystyle \int \frac {1} {xlnx} dx$

I tried doing it with substitution, parts, but neither would work.

Ha, I was thinking about doing that, but I was thinking too hard. I keep thinking I could not seperate $\displaystyle \frac {1}{xlnx}$ into $\displaystyle \frac {1}{x}$ and $\displaystyle \frac {1}{lnx}$
