Chapter Eleven — SGML Functions (continued)
Overview
The SGMLValueToString function converts a structured parameter value (pvalue) to a string within the context of the current element.
Syntax/Parameters
Syntax
string = SGMLValueToString ( dword pvalue, [handle hSGML], [dword token] )
Parameters
pvalue
A dword specifying a structured parameter value (can also be defined as a PVALUE).
hSGML
An optional handle to an SGML object. If omitted, only fixed values may be processed.
token
A dword specifying a reference HTML attribute or CSS property token. This value is required if the structure is PT_KEYWORD type.
Return Value
A string containing the translated value or an empty string on error. The value can be empty if the pvalue specifies a string which happens to be empty. Use the GetLastError and IsError functions to differentiate between an error and an empty string.
Remarks
This function operates in two modes: as a simple structured parameter value conversion and as a heap based conversion. The former does not require an SGML object. For any operation that requires a heap (strings, errors, arrays), an SGML object must be supplied with a value heap area.
Any items marked as PT_KEYWORD must have a token context.
Measurements are generally in 100ths of units except for inches which are 10000ths.
Errors processed by this function will return a string with “(error-description)”. The description may not be present if the underlying error is not set.
