Voici une méthode pour la bande des espaces de noms:
private static XElement StripNamespaces(XElement rootElement)
{
foreach (var element in rootElement.DescendantsAndSelf())
{
// update element name if a namespace is available
if (element.Name.Namespace != XNamespace.None)
{
element.Name = XNamespace.None.GetName(element.Name.LocalName);
}
// check if the element contains attributes with defined namespaces (ignore xml and empty namespaces)
bool hasDefinedNamespaces = element.Attributes().Any(attribute => attribute.IsNamespaceDeclaration ||
(attribute.Name.Namespace != XNamespace.None && attribute.Name.Namespace != XNamespace.Xml));
if (hasDefinedNamespaces)
{
// ignore attributes with a namespace declaration
// strip namespace from attributes with defined namespaces, ignore xml / empty namespaces
// xml namespace is ignored to retain the space preserve attribute
var attributes = element.Attributes()
.Where(attribute => !attribute.IsNamespaceDeclaration)
.Select(attribute =>
(attribute.Name.Namespace != XNamespace.None && attribute.Name.Namespace != XNamespace.Xml) ?
new XAttribute(XNamespace.None.GetName(attribute.Name.LocalName), attribute.Value) :
attribute
);
// replace with attributes result
element.ReplaceAttributes(attributes);
}
}
return rootElement;
}
Exemple d'utilisation:
XNamespace ns = "http://schemas.domain.com/orders";
XElement xml =
new XElement(ns + "order",
new XElement(ns + "customer", "Foo", new XAttribute("hello", "world")),
new XElement("purchases",
new XElement(ns + "purchase", "Unicycle", new XAttribute("price", "100.00")),
new XElement("purchase", "Bicycle"),
new XElement(ns + "purchase", "Tricycle",
new XAttribute("price", "300.00"),
new XAttribute(XNamespace.Xml.GetName("space"), "preserve")
)
)
);
Console.WriteLine(xml.Element("customer") == null);
Console.WriteLine(xml);
StripNamespaces(xml);
Console.WriteLine(xml);
Console.WriteLine(xml.Element("customer").Attribute("hello").Value);
