How to derive desired sequence from a string using standard java api?

I need to get parts of a string in a particular format. Tried everything from split, substring to pattern and matcher. but everytime it fails with one of the requirements.

Suppose

str = (((abc) shdj (def) iueexs (ghi)) mkek ONE(tree23) bjm开发者_如何学JAVA
(twooo(bug OR bag)) mvnj THR-EE(<*>$##))

And terms wanted are :

"Hard Coded Term1":abc
"Hard Coded Term2":def
"Hard Coded Term3":ghi
ONE:tree23
twooo:bug,bag
THR-EE:<*>$##

Provision to hard code the terms as in the case of first three. Help!Help!

Ugh, you need to first properly specify your requirements, preferably in BNF or equivalent. With that out of the way, you can find the hard coded terms via a regexp (^|[( ])[(]([^ )])[)] (use the 2nd group), and the other terms with a regexp like ([0-9a-zA-Z-_])[(]([^ )])[)] (use 1st group as name, 2nd group as value, but you will need to process further the 2nd group to split on operands).

You're in the neighborhood of doing language parsing. Just looking at it, it looks doable with a recursive descent parser, but with that one short example it's hard to tell for sure.

The tricky think looks to be distinguishing shdj (def) which should resuit in a "hard coded term 'def'" from ONE(tree23) which should return "ONE:tree23".
