XmlNamespaceManager.HasNamespace Method

Gets a value indicating whether the supplied prefix has a namespace defined for the current pushed scope.

Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)

public virtual bool HasNamespace (
	string prefix
)
public boolean HasNamespace (
	String prefix
)
public function HasNamespace (
	prefix : String
) : boolean
Not applicable.

Parameters

prefix

The prefix of the namespace you want to find.

Return Value

true if there is a namespace defined; otherwise, false.

To determine whether there is a default empty namespace defined, set prefix to String.Empty. If the method returns true, this indicates that there is a default namespace defined in the current scope. Returning false indicates that no default namespace is defined.

NoteNote:

xmlns:x= "" is illegal according to W3C Namespaces in XML recommendation.

The following example displays the default namespace, if one exists.

if (nsmgr.HasNamespace(String.Empty))
  Console.WriteLine(nsmgr.DefaultNamespace);

if (nsMgr.HasNamespace("")) {
    Console.WriteLine(nsMgr.get_DefaultNamespace());
}
