Matching nonempty lines with pyparsing

pyparsing, python

Solution

My take on it:

    from pyparsing import *

    # matches and removes end of line
    EOL = LineEnd().suppress()

    # line starts, anything follows until EOL, fails on blank lines,
    line = LineStart() + SkipTo(LineEnd(), failOn=LineStart()+LineEnd()) + EOL

    lines = OneOrMore(line)

    # Group keyword probably helps grouping these items together, you can remove it
    parser = Keyword("SOME_KEYWORD:") + EOL + Group(lines) + Keyword("ANOTHER_KEYWORD:") + EOL + Group(lines)
    result = parser.parseFile('data.txt')
    print result

Result is:

['SOME_KEYWORD:', ['line 1', 'line 2', 'line 3', 'line 4'], 'ANOTHER_KEYWORD:', ['line a', 'line b', 'line c']]

Problem

I am trying to make a small application which uses `pyparsing` to extract data from files produced by another program. These files have following format. ``` SOME_KEYWORD: line 1 line 2 line 3 line 4 ANOTHER_KEYWORD: line a line b line c ``` How can i construct grammar which will help to extract `line 1`, `line 2` ... `line 4` and `line a` .. `line c`? I am trying to make a construction like this ``` Grammar = Keyword("SOME_KEYWORD:").supress() + NonEmptyLines + EmptyLine.supress() +\ Keyword("ANOTHER_KEYWORD:").supress() + NonEmptyLines + EmptyLine.supress() ``` But i don't know how to define `NonEmptyLines` and `EmptyLine`. Thanks.
