[jdom-interest] newbie question: save changes to document

[graste]

Hi,

I have a question about saving changes to elements into an existing  
document. I retrieve an element using a simple xpath expression. After  
that I modify the element and want to write the changes back to the  
original document. How can I do this?

// code parts stripped (exception handling etc.)

String xpath = "/path/to/some/element";
Document document = builder.build(new File(pathToFile));
Element elem = (Element) XPath.selectSingleNode(document, xpath); // get  
element
elem.getChild("someElem").setText("someContent"); // do some modifications

// somehow save changes here

XMLOutputter outp = new XMLOutputter(Format.getCompactFormat()); // write  
document
outp.output(document, new FileOutputStream(new File(pathToFile))); // back  
to disk

Any suggestions to a JDom newbie? I' using the latest JDom version and  
have no problems reading XML files.

Thanks in advance.

Regards,

Steffen Gransow
