Thread: any better way for creating xml other than documentbuilder class??

Hi

I want to create a small xml file by using some nodes out of a larger xml file.
my approach:
1. parse large xml file using sax parser
2. select few nodes and instantiate a pojo class
2. using documentbuilder to create xml with the data members of pojo class.

(basically xml-to pojo-to xml)

my question:
any better way to do this???
(dom takes up memory and this kind of feels repetitive )

Hi
(posted in wrong place initially )

I want to create a small xml file by using some nodes out of a larger xml file.
my approach:
1. parse large xml file using sax parser
2. select few nodes from this xml and setting the values into a pojo class
2. using documentbuilder to create new xml getting data from the pojo class datamembers

(basically xml-to pojo-to xml)

my question:
any better way to do this???

Shortly speaking standard Java 7 API allows three approaches:

- DOM (it is your documentBuilder);
- SAX;
- JAXB.

The last is for direct mapping of pojos to XML and back with help of some annotations. You can easily find some tutorials if it is what you are looking for.

To be honest, I prefer JSON since it could be mapped to objects straightly.

As suggested JAXB is the easiest way provided you have a well defined schema for the xml to be parsed. As JAXB populates the nodes into POJO's. Please read tutorial on JAXB to proceed.
