Hello Muhammad,
I hope that you are using custom tags for this.
I would create a new custom tag to determine if the
rule is present in the collection...
<rule:RulePresent rule="ruleKey">
display table x
</rule:RulePresent>
This tag would then look in the collection for the
specific rule, not by iterating through the collection
but by trying to retrieve the rule by its key.
I would suggest using a key/value mapping collection,
do the look up on the key
collection.containsKey(ruleKey) if true then display
the tag body, if false then skip the tag body.
Hope this helps.
