Re: [rules-users] Handling Many Literal Matches Rules
You can do this with a single rule:
rule findHeadTail
when
ListPair( $pattern : pattern )
Document( $text : text matches $pattern )
then
System.out.println( $text );
end
where ListPair is a class maintaining two List<String> fields, heads and tails.
The getter String getPattern should return a value such as
".*(A|B|C)(X|Y|Z).*",
constructed from heads and tails.

Hi,
I have the following scenario:
List 1 of string values: "A", "B", "C"
List 2 of string values: "X", "Y", "Z"
Some text that might look like "AFFG DDGT AY FDD" (Important value in the
text is AY)
I need a rule for every string value from List 1 combined with every value
from List 2 for example:
rule
when text matches "AX"
then
end rule
rule
when text matches "AY"
then
end rule
rule
when text matches "AZ"
then
end rule
rule
when text matches "BX"
then
end rule
rule
when text matches "BY"
then
end rule
...
You get the idea ;-)
The lists might be big (50 entries each) and will be change constantly out
side the application.
What is the best approach for this kind of rules?
Thanks,
Rod
