java-xml急！

Question

具体要看你采用哪套parse了，不过一般都是往OutputStream中写，你可以创建一个FileOutputStream就可以创建文件了。

Answer 1

是jaxp.
呵呵，我也有这个想法，先建立一个filepath(temp.xml).
在文件中写入<?xml version='1.0'?>....
  factory=DocumentBuilderFactory.newInstance();
  tfactory=TransformerFactory.newInstance();
  DocumentBuilder builder=factory.newDocumentBuilder() ;
  Document doc=builder.parse(filepath) ;
......
然后就甩出这个exception:
