Grammar parser for parsing parliamentary debates?

Question

I'm looking to parse the plain text from a transcription tool (the goal is to render it into LegalDocML).

My issue is that I do not know where to start and learning a grammar parser is quite a steep learning curve. I'm looking for guidance as to what kind of parser would be appropriate for the problem.

My gut feel is that the below is a candidate for LR grammar tools as there might be some clear delimiters? (all caps for speaker, brackets for speaker role, square brackets to speech time) but also some NLP needs - for grievances the person the speech is addressed to is often loosely in the first sentence of the speech..

Any advice would be appreciated

as a sample:

SMALL BUSINESS ASSISTANCE GRANTS
Statement by Minister for Small Business
Statement
MR D.T. PUNCH (Bunbury — Minister for Small Business) [9.01 am]: I would like to bring to the attention of the house some recent changes made by the McGowan government to the small business assistance grants. As I have previously advised the house, in February the state government announced a $67 million level 1 COVID-19 business assistance package, and more recently a $72 million package for businesses impacted by level 2 public health and social measures, taking the total committed to COVID-19 business support to almost $1.7 billion over the past two years. The level 1 package includes $42 million in rent relief assistance and the level 2 package includes a $66.8 million small business hardship grants program.
Last month, a revision and expansion of the small business hardship grants program was announced.
