Input:

template header
company
subCompany
package dummyRule;
template "dummy-rule"
rule "dummy-rule"
when
  eval(true)
then
System.out.println("Hello World");
end
end template

There can be any number of words & empty lines between template header & package. Only words between template header & package are needed as output.

Expected Output:

Group 1: company
Group 2: subCompany
Group 3: (next word)
& so on...

What I Tried:

template header(\s+(\w+))+

Actual Result:

Group 1:  dummyRule
Group 2: dummyRule

what about firstly `replace`ing `\n` with `''`? – Dominik Matis Jan 25 '20 at 17:38

Your `template header(\s+(\w+))+` pattern has **two** capturing groups, so you only have **two**groups. Repeated capturing groups always keep the last value matched in the last iteration. – Wiktor Stribiżew Jan 25 '20 at 17:39
