Attribute Filter rule for different Shibboleth SP that shared entityID

[Supakit Kiatrungrit]

Hi,

We have integrated our IDP with two different SPs that they shared the same entity ID but different hostname
For example:
Host A: example1.com has entity ID as https://example1.com/shibboleth
Host B: example2.com has entity ID as https://example1.com/shibboleth

When look at the SP Metadata of Host A and Host B everything is identical except endpoint host of ArtifactResolutionService, SingleLogoutService, AssertionConsumerService are different.

Is there any way for IdP to set up attribute release rule (attribute-filter.xml) separately for Host A and Host B? 
If it is possible with scripting (https://wiki.shibboleth.net/confluence/display/SHIB2/IdPFilterRequirementScript), do anyone have an example that check the hostname from the metadata endpoint URL.

Thank you so much,
Nat
