Getting all values under a category [message #1721551]

Hi This is my grammar.

Query:
(key=Greeting)? (to=GroupTo)? from: Name

Greeting:
keyword='hello'
;

Name:
name=ID

GroupTo:
group+='and' name1=Name (','name1+=Name)*

;

I am trying to understand sentences like

hello john and jim from: tim

In the doGenerate method I want to retrieve the names only in GroupTo category. I am unable to take these name under one variable.

Instead of using name1 and name2 .I wish to use one variable to get all the names under Group.

var groupToNames =resource.allContents.filter(typeof(GroupTo)).map[name1].toIterable

How can I use one variable such that all Names under GroupTo is captured and I do not have to use name1 and name 2.

Is there a better way to represent the grammar or the retrieval in doGenerate method.
Also , I see that I cannot use the "to" variable to map.

Am I missing something.?

Basically you might want something like this:

GroupTo:
group+=Name ('and' group+=Name)*;

This will collect all member names in the collection-valued attribute 'group'. I'm not sure where exactly you want to have the ',' keyword as it is not mentioned in the concrete example.

Thank You for this.

GroupTo:
group+=Name ('and' group+=Name)*;

I wish to understand ,how can I add another category in the same rule.

For example I want to match

Australia and Jim
Jim and Australia
Australia and Australia
Jim and Jim

So ,in summary

I wish to match "COUNTRY/NAME and NAME/COUNTRY" in any order.
