[jdom-interest] Problem: element already has an existing parent

[Mark Bennett]

I think you want to add a b.detach(); right after you create it.

Subject: [jdom-interest] Problem: element already has an existing parent

Hi I try to get an xml document like

<root>
    <page>
        <a>
            <b>something1</b>
            <b>something2</b>
        </a>
    </page>
    <page>
        ...
    </page>
</root>

where page must be dynamically set, when a condition applies.
For that I tried something like

Document doc = null;
Element root = new Element("root");
Element page = new Element("page");
Element a = new Element("a");
while (b) {
    Element b = new Element("b");
    b.addContent("something");
    a.addContent(b);
    if (condition applies) {
       page.addContent(a);
       root.addElement(page);
       a = new Element("a");
       page = new Element("page");
    }
}

if try that, I get :
The element "page" could not be added as a child of "root": The element
already has an existing parent "root".

How can achieve something like that?

Jens
