STL file to a readable text file

Question

I am now studying 3d models (stl files and etc) and how it is made from scratch. What software do I need to use to see what's inside the stl file like this:

solid dart
    facet normal 0.00000E+000 0.00000E+000 -1.00000E+000
        outer loop
            vertex 3.10000E+001 4.15500E+001 1.00000E+000
            vertex 3.10000E+001 1.00000E+001 1.00000E+000
            vertex 1.00000E+000 2.50000E-001 1.00000E+000
        endloop
    endfacet
endsolid dart

I have been searching for those kinds of software but so far, no luck.

MeshLab (http://www.meshlab.net) is a widely used open source viewer for 3D models that handles well all the STL variants (and many other 3D files). Available for mac/win/linux

There is also an online version that runs in your browser http://www.meshlabjs.net
