i want have address nodes attributes output. problem there nested nodes have address node child. getting access child address problem. if again has child name address not want give me node have done in following code

public void find_node(string id_node)  {     xelement root = xelement.load("purchaseorder.xml");     ienumerable<xelement> address =         el in root.elements("address")         (string)el.attribute("type") == "buying"         select el;      foreach (xelement el in address)     {         var newelement = new xelement(                                 el.name.localname,                                 el.attributes(),                                 el.elements().where(o => o.name.localname != "address")                          );         console.writeline(newelement.tostring());     } } 

the desired output code be

<address type="buying">     <name>ellen adams</name> </address> 

but has empty output when running above function.

may ask have ride of empty output function?

if mean address elements regardless of location within xml, long matches attribute filter, can use descendants("address") instead :

ienumerable<xelement> address =                 el in root.descendants("address")                 (string)el.attribute("type") == "buying"                 select el;
