What is the difference between histrionic personality disorder and borderline personality disorder?

Just tried googling and after reading several articles, there is no good distinguishing explanation. Any good links or even your own explanation would be most helpful. Thanks in advance!

Histrionics feel validated from attention and tend to dress and act in ways to attract that attention. When someone stops giving them the attention they seek, they tend to take it as “this person does not like me anymore” and they drop that person or those people for those who will give them the validation they are looking for. Sadly by doing this, they overlook the people who may be sad or have their own struggles going on (maybe a family member died, or they got fired from work) and in return those friends will notice that they are pushed away and being ignored, which continues a cycle of attachment for the histrionic person.
   
Histrionic people tend to fall in the anxious-ambivalent category of attachment and feel a need to always have people around.   
   

Boarder-lines have a subconscious level of never feeling good enough and a fear of abandonment. They tend to seek out attention, but to much attention in return overwhelms them. This is because of their abandonment issues and subconsciously they push others away because they want to prove that “everyone leaves”. The fact that positive attention is foreign to them it can in turn create suspicion rather than feeling loved and accepted.   
   
Most borderlines will chase and then push away, and then go back to chasing. Whether it be with the same person, or dumping that person to chase someone new.   
   
Borderlines often fall into the [fearful] avoidant attachment category because they find relationships stressful (mostly just romantic) and in the end tend to almost always push the other away. Unless they find help to resolve this, the pattern continues.
