我想知道使用 DOM、SAX Parser 或 XMLPullParser 哪个更好更快.

推荐答案

这取决于你在做什么，如果你有非常大的文件，那么你应该使用 SAX 解析器，因为它会触发事件并释放它们，没有任何东西存储在内存，并且使用 SAX 解析器，您不能以随机方式访问元素，没有回头路！，但 Dom 允许您访问 xml 文件的任何部分，因为它将整个文件/文档保存在内存中.希望这个回答你的问题.

it depends on what are you doing , if you have very large files then you should use SAX parser since it will fire events and releasing them ,nothing is stored in memory ,and using SAX parser you can't access element in a random way there is no going back ! , but Dom let you access any part of the xml file since it keeps the whole file/document in memory . hope this answer you question .

如果您想知道哪个最快的解析器 Xerces 将是最快的，您会发现 SAX解析器应该给你比 Dom 更高的性能

if you want to know which fastest parser Xerces is going to be the fastest you'll find and SAX parser should give you more performance than Dom
