Hi,

I'm fairly new to the pyparsing and the mailing list, but I have
browsed through the email archives but I can't seem find how to parse
statements in any order.

#### Start Code ####
from pyparsing import *

Ident = Word(alphas, alphanums+"_")

type_name = Ident.setResultsName("name")
type = Group(Suppress(Keyword("type", caseless=True))+
type_name).setResultsName("type")
types = Group(ZeroOrMore(type)).setResultsName("types")

type2_name = Ident.setResultsName("name")
type2 = Group(Suppress(Keyword("type2", caseless=True))+
type_name).setResultsName("type2")
types2 = Group(ZeroOrMore(type2)).setResultsName("types2")

content = Each([types, types2])

grammar = And([content]).setResultsName("content")

parser = grammar.parseString( testString )
parser.asXML()

####

It successfully parses the following input:

type IDL
type ODL

type2 Ika
type2 Nfkb

and produces

<content>
  <types>
    <type>
      <name>IDL</name>
    <type>
    <type>
      <name>ODL</name>
    <type>
  </types>
  <types2>
    <type2>
      <name>IDL</name>
    <type2>
    <type2>
      <name>Nfkb</name>
    <type2>
  </types2>
</content>
But does not parse correctly the next input, which is basically the
types swapped over:

type2 Ika
type2 Nfkb

type IDL
type ODL

It produces the following without errors; It misses the second set of types:

<content>
  <types>
  </types>
  <types2>
    <type2>
      <name>IDL</name>
    <type2>
    <type2>
      <name>Nfkb</name>
    <type2>
  </types2>
</content>

Ideally I'd like the parser to pick up both sets of types and place
them in their respective collection(namely types and types): e.g it
should be able to process the second input and the following and be
able to produce the first output or similar:

type2 Ika
type IDL

type2 Nfkb
type ODL

Any help would greatly be appreciated.
