Template based text parsing ;-)

RTE wants to be a universal solution to parse structured texts. It needs two input:

• the text you want to parse
• and the template, which defines patterns, places of output variables and controls the parser algorythm.

In the end it will produce a JSON-like output with the variables and their results.

• parsing
  • the main thing: capture groups and put the matched value into a variable
  • handle optional input lines
  • handle multiline input blocks
  • handle repeating input lines
  • handle repeating input blocks - be able to build a list
  • handle recursive blocks - "list in list" problem
  • maybe some extra parsing on captured values (replace, cast)
• output
  • JSON-like output
  • mechanism to fill a POJO structure
  • mechanism to list used properties from template, and also verify a potential result POJO class
