I have a trigger that successully fires upon the system receiving an inbound email related to a Case record. This trigger's purpose is to stamp the inbound email's body into a text field on the Case object. The working code is as follows:

trigger CopyEmailReplyBody on EmailMessage (after insert) {
    Set<ID> caseSet = new Set<ID>();
    Map<Id, String> emailBodyMap = new Map<Id, String>{};
        for (EmailMessage so : Trigger.new) {
            if(so.ParentId.getSObjectType() == Case.sObjectType && so.Incoming){
                caseSet.add(so.parentid);
                emailBodyMap.put(so.ParentId, so.TextBody);
            } 
        }
        Map<Id,case> caseMAP = new Map<Id,case>([SELECT Latest_Email_Reply__c FROM Case WHERE id in:caseSet]);  
        for(Case c:caseMAP.values()){
        
            c.Latest_Email_Reply__c = emailBodyMap.get(c.Id);
        
        update c;
        }
}

My users just asked for a new requirement in that the values stamped into the text field "[FromAddres] + BR() + [FromName] + BR() + [Subject] + BR() + BR() + [Body]". Sounded simple enough, but I ran into a silly issue: 

I received the error "Error: Compile Error: unexpected token: '<' at line 34 column 67". I have tried to play around with different ways of adding in <BR/>'s into this field, but continue to run into this same error code. Please see below for the updated work in progress code:

trigger CopyEmailReplyBody on EmailMessage (after insert) {
    Set<ID> caseSet = new Set<ID>();
    Map<Id, String> emailBodyMap = new Map<Id, String>{};
        for (EmailMessage so : Trigger.new) {
            if(so.ParentId.getSObjectType() == Case.sObjectType && so.Incoming){
                caseSet.add(so.parentid);
                emailBodyMap.put(so.ParentId, so.TextBody);
            } 
        }
    Map<Id, String> emailSubjectMap = new Map<Id, String>{};
        for (EmailMessage so : Trigger.new) {
            if(so.ParentId.getSObjectType() == Case.sObjectType && so.Incoming){
                caseSet.add(so.parentid);
                emailSubjectMap.put(so.ParentId, so.Subject);
            } 
        }
    Map<Id, String> emailFromAddressMap = new Map<Id, String>{};
        for (EmailMessage so : Trigger.new) {
            if(so.ParentId.getSObjectType() == Case.sObjectType && so.Incoming){
                caseSet.add(so.parentid);
                emailFromAddressMap.put(so.ParentId, so.FromAddress);
            } 
        }       
    Map<Id, String> emailFromNameMap = new Map<Id, String>{};
        for (EmailMessage so : Trigger.new) {
            if(so.ParentId.getSObjectType() == Case.sObjectType && so.Incoming){
                caseSet.add(so.parentid);
                emailFromNameMap.put(so.ParentId, so.FromName);
            } 
        }  
        Map<Id,case> caseMAP = new Map<Id,case>([SELECT Latest_Email_Reply__c FROM Case WHERE id in:caseSet]);  
        for(Case c:caseMAP.values()){
        
            c.Latest_Email_Reply__c = emailFromNameMap.get(c.Id) + <br /> + emailFromAddressMap.get(c.Id) + <br /> + <br /> + emailSubjectMap.get(c.Id) + <br /> + <br /> + emailBodyMap.get(c.Id);
        
        update c;
        }
}

Thoughts?
