Example
// Export all customers
HExportXML(CUSTOMER, "C:\TEMP\Customer.xml", hExpCreation)
Syntax
<Result> = HExportXML(<File name> [, <Path of XML file> [, <List of items to export>]] [, <Options> [, <Progress bar>]])
<Result>: Boolean
  • True if the operation was performed,
  • False if a problem occurred. HError is used to identify the error.
<File name>: Character string (with or without quotes)
Name of data file used. If this name is not specified, HExportXML handles the last data file used by the last function for HFSQL management (starting with the letter H).
<Path of XML file>: Optional character string
Full path of XML file to generate.
If this parameter is not specified, a <File name>.XML file will be generated in the current directory.
<List of items to export>: Optional character string
List of names of items to export. The names are delimited by single quotes and separated by commas or CR characters. The names of composite key items, binary items and binary memo items are ignored.
If this parameter corresponds to an empty string (""), all the items in the data file (except composite key, binary and binary memo items) are exported.
<Options>: Optional Integer constant
Specifies the creation mode of the XML file:
hExpCreationIf the XML export file already exists, it is overwritten. An error occurs if this option is not specified and if the XML file exists.
hExpBreakableThe export can be interrupted by pressing the Esc key on the keyboard.
If the export is interrupted, the XML file is valid and it only contains the records exported before the interruption.
hExpNormal
(default value)
Standard operating mode.
hExpWithoutXSLThe style sheet (".XSL" file) is not created.
<Progress bar>: Optional character string (with or without quotes)
Name of Progress Bar control or name of window used to show the progress of file creation.
Remarks

Exporting the query content

To export the query content, you must initialize the query (HExecuteQuery) before using HExportXML.

Exporting a single record

To export a single record to an XML string, use HRecordToXML.

Array items

If one of the exported items is an array item, each element of the array item is exported in a new level:
<FILE>
<ITEM1>data of item 1</ITEM1>
<ITEM2>data of item 2</ITEM2>
<ARRITEM>
<ARRITEM_1>data of element 1</ARRITEM_1>
<ARRITEM_2>data of element 2</ARRITEM_2>
<ARRITEM_3>data of element 3</ARRITEM_3>
</ARRITEM>
...
</FILE>
Reminder: Composite key, binary memo or binary items are ignored.

Miscellaneous

The document entity of the generated XML file is named HF_DOCUMENT.
