各位仁兄, 帮帮忙吧!

Question

haha 我没有,
不过,大过年的,帮你顶一下!

Answer 1

jdk的源码?哪有jdk的源码呀?这位仁兄指点明路.

Answer 2

你的jdk中的 .java文件用记事本(推荐用editplus)打开就是啊
如果是.class文件可以反编译打开

Answer 3

用过NanoXML吗？life版才6k(两个文件），它完成了XML的基本读写操作，很不错的；

Answer 4

随便找一个开源的xml解析器来改改不就行了

Answer 5

没用过NanoXML， 有源码嘛， 给发个怎样？

Answer 6

xerces
http://xml.apache.org/xerces2-j/index.html

Answer 7

是啊。你看看其他XML解析器实现的方法
