[ACCEPTED]-How can I remove empty xmlns attribute from node created by XElement-linq-to-xml
Accepted answer
It's all about how you handle your namespaces. The 6 code below creates child items with different 5 namespaces:
XNamespace defaultNs = "http://www.tempuri.org/default";
XNamespace otherNs = "http://www.tempuri.org/other";
var root = new XElement(defaultNs + "root");
root.Add(new XAttribute(XNamespace.Xmlns + "otherNs", otherNs));
var parent = new XElement(otherNs + "parent");
root.Add(parent);
var child1 = new XElement(otherNs + "child1");
parent.Add(child1);
var child2 = new XElement(defaultNs + "child2");
parent.Add(child2);
var child3 = new XElement("child3");
parent.Add(child3);
It will produce XML that looks 4 like this:
<root xmlns:otherNs="http://www.tempuri.org/other" xmlns="http://www.tempuri.org/default">
<otherNs:parent>
<otherNs:child1 />
<child2 />
<child3 xmlns="" />
</otherNs:parent>
</root>
Look at the difference between 3 child1, child2 and child3. child2 is created using the default namespace, which 2 is probably what you want, while child3 is what 1 you have now.
