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，因为它会触发事件和释放他们，没有什么是存储在内存，并使用SAX解析器，你不能访问以随机的方式有没有回头路元！ ，但大教堂让你访问任何部分的XML文件，因为它使整个文件/文件在内存中。希望这回答你的问题。

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 .
