c# - XML: let child-node inherit parent-node namespace? -

i'm trying create xml nodes runtime using xpath c#. see xml below:

<package xmlns:m2="http://schemas.microsoft.com/appx/2013/manifest" xmlns="http://schemas.microsoft.com/appx/2010/manifest">   <application>     <m2:visualelements>        <!--- insert child nodes here have namespace 'm2' ---->     </m2:visualelements>   </application> </package> 

currently i'm doing following:

xelement visualelements = doc.descendants().singleordefault(p => p.name.localname == "visualelements"); visualelements.add(new xelement(doc.root.getdefaultnamespace() + "initialrotationpreference")); 

i know wrong since reference default namespace, result in being added:

<initialrotationpreference /> 

when want:

<m2:initialrotationpreference /> 

is there way access parent-nodes namespace (m2) without "knowing" prefix or namespace-url?

thank you!

your document root's namespace http://schemas.microsoft.com/appx/2010/manifest. use 1 visualelements:

xname name = visualelements.name.namespace + "initialrotationpreference" 

or specify explicitly:

xname name = xname.get("initialrotationpreference",      "http://schemas.microsoft.com/appx/2013/manifest"); 

then add element name:

visualelements.add(new xelement(name));
