ExportToXMLBuffer, ScriptExportToXMLBuffer Methods

Applies To

fpSpread control

Description

Saves the sheet in XML format and stores the information in a buffer.

Syntax

C++

BOOL CSpreadSheet::ExportToXMLBuffer(LPCTSTR Root, LPCTSTR Collection, BSTR* Buff, long Flags, LPCTSTR LogFile);

Visual Basic

fpSpread1.ExportToXMLBuffer(ByVal Root As String, ByVal Collection As String, Buff As String, ByVal Flags As ExportToXMLConstants, ByVal LogFile As String) As Boolean

Note: The ScriptExportToXMLBuffer method uses the same syntax except method parameters that are not passed "ByVal" are declared as variants. For more information on Script methods, see Scripting Environment Usage.

Parameters

The following parameters are available:

Parameter	Description
Root	Root element to use in the XML file Do not use spaces in this string.
Collection	Collection element to use in the XML file Do not use spaces in this string.
Buff	Returns the handle to the buffer
Flags	Whether to export formatted or unformatted data Use one of the following values:
	Constant	Value	Description
	ExportToXMLFormattedData	0	To export data as formatted data
	ExportToXMLUnFormattedData	1	To export data as unformatted data
LogFile	Path and file name of log file to create If you do not provide a file name, the export will not create a log file. If you do not want to create a log file, set this parameter to "".

Remarks

Use this method to export a sheet to XML data in a buffer. The export creates XML data that provides the sheet data as a set of tagged XML elements. The XML data created conforms to XML 1.0 guidelines.

This method is called for the current sheet setting unless you first set the Sheet property to specify the sheet with which you want to work.

Use the Root and Collection parameters to specify the root node necessary for valid XML data. The export uses the column headers in the sheet as the child elements within each collection element. If you provide custom text for the column headers, do not use spaces in the text; XML tags cannot contain spaces. If the sheet does not contain text in the column headers, the child element tags in the XML file default to <A>, <B>, <C>, and so forth. The export ignores any row headers.

Use the Flags parameter to specify whether formatted or unformatted data is saved to the XML file. For more information about formatted and unformatted data, see Formatted and Unformatted Data.

The following table summarizes the formats to which you can save data from a workbook or sheet:

To Save To . . .	Use Method
Binary file (proprietary format)	SaveToFile
Tab-delimited file	SaveTabFile or SaveTabFileU
Delimited file (offers user-defined delimiters)	ExportToTextFile or ExportRangeToTextFile or ExportToTextFileU or ExportRangeToTextFileU
Excel-formatted file	ExportExcelBook or ExportToExcel
HTML file	ExportToHTML or ExportRangeToHTML
XML file	ExportToXML or ExportRangeToXML
XML buffer	ExportToXMLBuffer or ExportRangeToXMLBuffer
An array	GetArray

Note: Call this method if you use the Spread control in a scripting environment (for example, Microsoft's Visual InterDev or Internet Explorer) or a non-scripting environment. However, if you want to use the Spread control in a scripting environment and you want to change any parameter that is not passed "ByVal", you must set the ScriptEnhanced property to True and call the ScriptExportToXMLBuffer method. ScriptExportToXMLBuffer method parameters that are not passed "ByVal" are declared as variants.

For instructions and more information about saving data to a buffer, see Saving to a Buffer. For more information about XML export, see XML File Export (online PDF manual). XML File Export lists and describes the method in which Spread property settings are interpreted in the XML data.

Return Type

True if successful; otherwise, False.
