Public Shared Function EncodeName (
	name As String
) As String

Parameters

name
Type: System.String

A name to be translated.

Return Value

Type: System.String

Returns the name with any invalid characters replaced by an escape string.

This method translates invalid characters, such as spaces or half-width Katakana, that need to be mapped to XML names without the support or presence of schemas. The invalid characters are translated into escaped numeric entity encodings.

The escape character is "_". Any XML name character that does not conform to the XML 1.0 spec (fourth edition) recommendation is escaped as _xHHHH_. The HHHH string stands for the four-digit hexadecimal UCS-2 code for the character in most significant bit first order. For example, the name Order Details is encoded as Order_x0020_Details.

The underscore character does not need to be escaped unless it is followed by a character sequence that together with the underscore can be misinterpreted as an escape sequence when decoding the name. For example, Order_Details is not encoded, but Order_x0020_ is encoded as Order_x005f_x0020_. No shortforms are allowed. For example, the forms _x20_ and __ are not generated.

This method guarantees the name is valid according to the XML specification. It allows colons in any position, which means the name may still be invalid according to the W3C Namespace Specification. To guarantee it is a valid namespace qualified name use EncodeLocalName for the prefix and local name parts and join the result with a colon.

The following example encodes and decodes names.

Imports System
Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

     ' Encode and decode a name with spaces.
     Dim name1 as string = XmlConvert.EncodeName("Order Detail")
     Console.WriteLine("Encoded name: " + name1)
     Console.WriteLine("Decoded name: " + XmlConvert.DecodeName(name1))

     ' Encode and decode a local name.
     Dim name2 as string= XmlConvert.EncodeLocalName("a:book")
     Console.WriteLine("Encoded local name: " + name2)
     Console.WriteLine("Decoded local name: " + XmlConvert.DecodeName(name2))

  end sub
end class
