Ideas for parsing this text?

A couple of comments first:
- What is the significance of '"[' vs. '[' ?  I stripped them all out
using
    text = text.replace('"[','[')
- Your input text was missing 5 trailing ]'s.

Here's the parser I used, using pyparsing:


from pyparsing import nestedExpr,Word,alphanums,QuotedString
from pprint import pprint

content = Word(alphanums+"_.") | QuotedString('"',multiline=True)
structure = nestedExpr("[", "]", content).parseString(text)

pprint(structure.asList())


Prints (I've truncated the long lines, but the long quoted strings do
parse intact):

[['propertySet',
  [['resourceProperties',
    [[['description',
       'This is a required \nproperty. This is an actual data...
      ['name', 'databaseName'],
      ['required', 'true'],
      ['type', 'java.lang.String'],
      ['value', 'DB2Foo']],
     [['description',
       'The JDBC connectivity-type of a data \nsource. If you...
      ['name', 'driverType'],
      ['required', 'true'],
      ['type', 'java.lang.Integer'],
      ['value', '4']],
     [['description',
       '"The TCP/IP address or host name for the DRDA server."'],
      ['name', 'serverName'],
      ['required', 'false'],
      ['type', 'java.lang.String'],
      ['value', 'ServerFoo']],
     [['description',
       'The TCP/IP port number where the \nDRDA server resides.'],
      ['name', 'portNumber'],
      ['required', 'false'],
      ['type', 'java.lang.Integer'],
      ['value', '007']],
     [['description', '"The description of this datasource."'],
      ['name', 'description'],
      ['required', 'false'],
      ['type', 'java.lang.String'],
      ['value', []]],
     [['description',
       'The DB2 trace level for logging to the \nlogWriter ...
      ['name', 'traceLevel'],
      ['required', 'false'],
      ['type', 'java.lang.Integer'],
      ['value', []]],
     [['description',
       'The trace file to store the trace output. \nIf you ...
       ]]]]]]]
