WriteProcessingInstruction (Compact 7)

3/12/2014

This method writes a processing instruction.

Syntax

HRESULT WriteProcessingInstruction (
  const WCHAR* pwszName, 
  const WCHAR* pwszText
);

Parameters

  • pwszName
    The name of the processing instruction. This parameter cannot be empty or NULL.
  • pwszText
    The text content of the processing instruction. NULL is the same as an empty string.

Return Value

This method returns S_OK if no error is generated.

Remarks

The writer creates a processing instruction by writing the provided name and text with a space after the name.

If the pwszText parameter is NULL, this method returns S_OK and writes a processing instruction without any text content.

If the text block provided contains the characters "?>" that signifies the end of a processing instruction, the writer inserts a space after the "?" character. This change prevents the writer from producing an XML document that is not well-formed.

The following code shows the use of WriteProcessingInstruction:

if (FAILED(hr = pWriter->WriteProcessingInstruction(L"xml-stylesheet",
    L"href=\"mystyle.css\" title=\"Compact\" type=\"text/css\"")))
{
    wprintf(L"Error, Method: WriteProcessingInstruction, error is %08.8lx", hr);
    return -1;
}
