NameTable Class
Assembly: System.Xml (in system.xml.dll)
Several classes, such as XmlDocument and XmlReader, use the NameTable class internally to store attribute and element names. When an element or attribute name occurs multiple times in an XML document, it is stored only once in the NameTable.
The names are stored as common language runtime (CLR) object types. This enables you to do object comparisons on these strings rather than a more expensive string comparison. These string objects are referred to as atomized strings.
The following example compares two element names.
Dim nt As NameTable = New NameTable() Dim book As object = nt.Add("book") Dim price As object = nt.Add("price") ' Create the reader. Dim settings As XmlReaderSettings = New XmlReaderSettings() settings.NameTable = nt Dim reader As XmlReader = XmlReader.Create("books.xml", settings) reader.MoveToContent() reader.ReadToDescendant("book") If (System.Object.ReferenceEquals(book, reader.Name)) ' Do additional processing. End If
//Create the reader.
XmlTextReader rdr = new XmlTextReader("book.xml");
NameTable nt = new NameTable();
String name = nt.Add("book");
while (rdr.Read()) {
}
if (rdr.get_NameTable().Get("book").Equals(name)) {
Console.WriteLine("matches!");
}
