Regex (benannt) Gruppen, die

Question

in zufälliger Reihenfolge (Python re) zeigen Ich versuche, ein Spiel von RegEx genannten Gruppen zu tun (preArgs, apm1Args, midArgs, apm2Args, postArgs) aufgeführt in der RegEx unten, die in zufälliger Reihenfolge erscheinen.
Ich bin in der Lage -Test String1, aber nicht die Test-String2 unten anzupassen:

ich die folgenden Anforderungen erfüllen müssen:

kann

1. Jede der Gruppe vorhanden 1 sein oder mehr (wegen des übrig gebliebenen Mülls); oder es ist fehlt insgesamt ...

2. Jede der apm1Args und apm2args immer mit 1 oder mehr -D Schalter zusätzlich zu einzigartigen javaagent Gläser erscheinen.

ich versucht, einige OR (|) Optionen (=?) Positiven Blick in die Zukunft, aber kein Glück und in das Labyrinth zu verirren ... My Trials:

Answer 1

Sie könnten ein pyparsing Ansatz finden erhalten Sie gehen schneller dann regex Gerangel.Hier ist ein Parser, der Ihre beiden Test Strings verarbeiten:

import pyparsing as pp 

# just some punctuation 
COLON,EQ = map(pp.Suppress, ':=') 

# expressions for key=value,... switches 
subkey = pp.Word(pp.alphas) 
subvalue = pp.pyparsing_common.integer | pp.Word(pp.printables, excludeChars=',') 
key_value_list = pp.Dict(pp.delimitedList(pp.Group(subkey + EQ + subvalue))) 

# parse switches 
switch_key = pp.Word('-', pp.alphas).setParseAction(lambda t: t[0][1:].lower()) 
switch_value = key_value_list | subvalue 
switch = switch_key + pp.Optional(COLON + switch_value) 

# -D definitions 
java_path_name = pp.delimitedList(pp.pyparsing_common.identifier, delim='.', combine=True) 
defn = (pp.Suppress("-D") + java_path_name.leaveWhitespace() 
     + EQ.leaveWhitespace() 
     + pp.Optional(subvalue().leaveWhitespace())) 

# define parser for the entire line - use Dict class to define dynamic key-value structures instead of just 2-tuples 
parser = pp.Dict(pp.OneOrMore(pp.Group(defn | switch)))
