Checks to see whether the given XML node has the exact attributes given in the attributes
hashmap

@param checkSimilarValues If true, will also check to make sure that the given node's
       attributes also have the exact same values as the ones given in the attributes HashMap.
@return True if the node has only the attributes the are given by the HashMap (no more and no
        less attributes). If {@param checkSimilarValues} is true then only returns true if the
        node shares attributes with the given attribute list exactly.
