java - Regex for instances in STEP-files?

Question

I have to parse some STEP-files (ISO-10303-21) from different CAD-Systems and they are always structured differently. This are the forms that might appear:

#95=STYLED_ITEM('',(#94),#92);
#12 = CARTESIAN_POINT ( 'NONE',  ( 1.213489432997839200,
5.617300827691964000, -7.500000000000001800 ) ) ;
#263 = TEST ( 'Spaces must not be ignored here' ) ;

I thought that a regular expression would help me, so I created this one (http://rubular.com/r/EtJ25Hfg77):

(#d+)s*=s*([A-Z_]+)s*(s*(.*)*s*)s*;

This gives me:

Match 1:
1: #95
2: STYLED_ITEM
3:

Match 2:
1: #12
2: CARTESIAN_POINT
3:

Match 3:
1: #263
2: TEST
3:

So the first two groups are working as supposed. But I also need the attributes inside the parantheses like this:

Match 1:
1: #95
2: STYLED_ITEM
3: ''
4: (#94)
5: #92

Match 2:
1: #12
2: CARTESIAN_POINT
3: 'NONE'
4: ( 1.213489432997839200, 5.617300827691964000, -7.500000000000001800 )

Match 3:
1: #263
2: TEST
3: 'Spaces must not be ignored here'

Please help me finding the correct expression for the last group ((.*) at the moment).

With an AGPL license for non-commercial use JSDAI is free and open source java toolkit for working with STEP files

http://www.jsdai.net/

BSD license, so always free and open source is the STEPcode project which generates C++ and python API's and example STEP file reader/writer, which is used by other open source projects such as BRL-CAD, SCView and OpenVSP.

www.stepcode.org

OpenCasCade has C++, pythonOCC has python, and node-occ has javascript API's for working with data that is translated from STEP, and are also free and open source. OCE works across more platforms and has more bug fixes
