    Exclamation Split QDomDocument to new QDomDocument

    Hi guys,

    I have an xml document and I need copy part of the content to a new xml document, following an example:

    Qt Code:
    1. <?xml encoding="utf-8" ?>
    2. <Library>
    3. <Location>
    4. <Test> <---- split here
    5. .....
    6. .....
    7. </Test>
    8. <Test2>
    9. .....
    10. .....
    11. </Test2>
    12. <Location>
    13. </Library>
    To copy to clipboard, switch view to plain text mode 

    I want to create a new document xml taking the "Test" tag as my root element. How can I do that? The next few snippets of code:

    Qt Code:
    1. ...
    2. xml.setContent(b); // It's ok, its working.
    3. QDomElement root = xml.documentElement();
    4. QDomNode node = root.firstChild();
    5. ...
    To copy to clipboard, switch view to plain text mode 

    Thanks,

    Marcelo E. Geyer

    Try with QDomNode::save().

    Ok, I want to put the contents of that xml in a QByteArray or QString, QDomNode::toDocument( ) thought to use, but is returning empty.

    Because the node is not the document node. QDomNode::toDocument() docs clearly states:

    You can also use QDomDocument::importNode().
