Estou tentando analisar o despejo de dados de estouro de pilha, uma das tabelas é chamada posts.xml, que possui cerca de 10 milhões de entradas. Exemplo de xml:

Gostaria de analisar este xml, mas carregue apenas certos atributos do xml, que são Id, PostTypeId, AcceptedAnswerId e outros 2 atributos. Existe uma maneira no SAX para que ele carregue apenas esses atributos? Se houver, então como? Sou muito novo no SAX, portanto, algumas orientações ajudariam.

Caso contrário, carregar a coisa toda seria apenas lento e alguns dos atributos não serão usados de maneira alguma, por isso é inúti

Uma outra pergunta é que seria possível pular para uma linha específica que tenha um ID de linha X? Se possível, como faço isso?
