If your doc is parsed in memory, you're only changing the "in-memory"
version of the file2.xml; not actually writing it back to disk...
So your output of 0 on the screen, but 400 still in the disk file would be

see this code snippet;
org.jdom.input.SAXBuilder builder = new org.jdom.input.SAXBuilder();
Document doc = builder.build(new
Element kid= element.getChild("rating");
String x =kid.getContent();
System.out.println("value of x-- rating is" +x+"\n\n");
"file2" is an existing xml file;
it has an attribute, by name "rating" ( <rating>400</rating> ).
In this code we are trying to set that to Zero ( i don't know if it will be
considered as a string or is there a way of maintaining the actual data
type, if any ; because actually "rating" keeps integer values).
When we use,
XMLOutputter fmt = new XMLOutputter();
The output on the console gives the value of "rating" as 0.
But when u open the actual file , "file2.xml", the value of rating is not
changed; the old 400 only;
The question is how to modify the value of a particular attribute( element)
in an already existing XML files ?
Thanks in advance
