Stored procedures
XMLSavePosition (Function)
In french: XMLSauvePosition
Stores the current position in the XML document. This enables you to temporarily suspend the current process in order for the XML document to be used somewhere else (to perform checks for example). The context saved can be restored by XMLRestorePosition. Then, the main process can continue.
Note: XMLSavePosition saves the current filter (the filter is implemented by XMLFind).
Reports and Queries
IF XMLDocument("MyXMLDoc", XMLCode) = True THEN
// Find the links
XMLFind("MyXMLDoc", "a", XMLTag)

TheXMLPosition is int = XMLSavePosition("MyXMLDoc")
XMLChild("MyXMLDoc")
Trace(XMLData("MyXMLDoc"))
// Process
XMLRestorePosition("MyXMLDoc", TheXMLPosition, XMLRPFilter)
END
// Next element in the search
XMLNext("MyXMLDoc")
 END
END
Syntax
<Result> = XMLSavePosition(<XML document>)
<Result>: Integer
  • Number of the position that was saved,
  • -1 if an error occurred.
<XML document>: Character string (with quotes)

Remarks

Saving several positions

XMLSavePosition can be used several times to save several positions in the XML file. To do so, assign the position to different integer variables. Then, these different positions can be restored by XMLRestorePosition.

XML functions and threads

If your application uses threads, the XML document is shared between all these threads. See Managing threads for more details.
