Is it possible to do the following in java :
I want to parse strings and store them in a list and eventually store
it in a table.

The problem is strings have substrings which appear in different
positions and have different delimiters  . I have given examples of
strings.

I am thinking of the following
==========================

Have formats defined for Strings ( as shown below)


Can we map a string to a particular format with this delimiter and
build a "key/value" list ( which can be dumped into db. Key matches
column name)

I dont know if this is a good idea and since i am new to java, I dont
know how this can be done in java . Any ideas will be of great help.
I want a common parser to dump these values .

Thanks

All you might need is something like this:

Pattern delimiter = Pattern.compile( " |\||\<|\>");

Then use split.
