Look into SAX Parser . Also, do a search for your terms - there are a ton of questions about this topic.

Answer 3

您是否阅读了Java教程中有关XML的线索 ？

Answer 4

You should use an XML library like XOM . You can then use it to query the XML document using XPATH. XOM offers a tutorial .

Answer 5

如果您的xml文件是基于树的，则使用DOM，如果未嵌套，则使用SAX，比DOM快。

Answer 6

添加到@user651407点，如果您只想读取XML然后去SAX ，它将以串行方式解析XML ，这样速度更快，但是如果您想执行更复杂的操作（例如添加，更新或删除节点），请继续DOM但DOM有局限性
1. required more memory as entire XML is loaded at a time.
2. Slow in processing as it is a tree based parser.
