SGMLGetItemResult Function

Overview

The SGMLGetItemResult function returns status and error data for the last item parsed.

Syntax/Parameters

Syntax

dword = SGMLGetItemResult ( handle hSGML );

Parameters

hSGML

A handle to an SGML Object.

Return Value

Returns a 32-bit dword result code using bitwise flags. On error, a formatted error code will be returned and can also be retrieved using the GetLastError function. Note that the top 4-bits of the result are always zero so as to not conflict with the formatted error code.

Remarks

The bitwise result codes are as follows:

	SPI_RC_BREAK_NORMAL	0x00000000	Broke on Space, ';' or '.'
	SPI_RC_BREAK_ELEMENT	0x00000001	Broke on Start of Tag
	SPI_RC_BREAK_CHAR	0x00000002	Broke on Start of Char Entity

Each parameter also has error bits. Certain error conditions will result in the parser stopping while moving through a tag. For example, forgetting the P element:

< STYLE="text-align: center">

Will have the SPI_RC_NO_CLOSE_ERROR flag set since the ‘=’ character is interpreted as part of the element name and therefore is in error, as such the parse is stopped. On calling for the next items, the parser will return the remainder of the tag as text and spaces:

1 -- "text-align:

2 --

3 -- center">
