Microsoft XML Core Services (MSXML) 5.0 for Microsoft Office - SAX2 Reference

endPrefixMapping Method

Ends the scope of the prefix-URI namespace mapping.

[Visual Basic]

The reader calls this method after the corresponding endElement method.

Implementation Syntax

Sub endPrefixMapping(strPrefix As String)

Parameters

strPrefix
The prefix being mapped.

Return Values

If failed, the ContentHandler raises a trappable error.

Example

The following example shows how to use the endPrefixMapping method to indicate that a namespace prefix has been ended or discontinued in the document.

Private Sub IVBSAXContentHandler_endPrefixMapping(strPrefix As String)
    Dim msg As String
    msg = "End prefix mapping." & vbCrLf & _
          "strPrefix: " & strPrefix & vbCrLf
    Form1.TextBox1.Text = Form1.TextBox1.Text & msg
End Sub
[C/C++]

This event always occurs after the corresponding endElement event, but the order of the endPrefixMapping events is not otherwise guaranteed.

Syntax

HRESULT endPrefixMapping(
   [in] const wchar_t * pwchPrefix,
   [in] int cchPrefix);

Parameters

pwchPrefix [in]
The prefix being mapped.
cchPrefix [in]
The length of the prefix string.

Return Values

S_OK
The value returned if no errors occur.
E_FAIL
The value returned if the parse operation should be aborted.

Remarks

The information from this event is not necessary for normal namespace processing. The reader automatically replaces prefixes for element and attribute names when the "http://xml.org/sax/features/namespaces" feature is set to True (the default).

There are cases, however, when applications need to use prefixes in character data or in attribute values and they cannot safely be expanded automatically. In these cases, the startPrefixMapping and endPrefixMapping methods can supply the information needed to expand prefixes.

There is no guarantee that the startPrefixMapping and endPrefixMapping events are properly nested relative to each other. All startPrefixMapping events occur before the corresponding startElement event, and all endPrefixMapping events occur after the corresponding endElement event, but their order is not otherwise guaranteed.
