XMLParent (Function) In french: XMLParent Positions on the parent element of current element (tag or attribute). To select an element, use the functions for XML search and browse ( XMLFirst, XMLLast, XMLChild, ...).
// Browse performed by XMLFirst and XMLNext ...
// Positions on "<order>" element
XMLLast("XMLOrd")
// moves one level up and positions on the "<number>" element
XMLParent("XMLOrd")
// Retrieves the order number
OrdNum is int = Val(XMLData("XMLDoc")) // contains 1
// Positions on the next element
XMLNext("XMLOrd")
// Retrieves the order date
OrdDate is string = XMLData("XMLOrd") // "11/20/2012"
Syntax
<Result> = XMLParent(<XML document>)
<Result>: Boolean - True if an element was found,
- False otherwise. If an error occurs:
- The current position remains unchanged.
- The ErrorOccurred variable is set to True. To get more details on the error, use ErrorInfo.
<XML document>: Character string Name of the XML document used. This document contains the XML code to study and it was created by XMLDocument. Remarks Handling elements in the XML code Using XMLParent during a search If a search is in progress, XMLParent cancels this search (see XMLFind). XML functions and threads If your application uses threads, the XML document is shared between all these threads. For more details on threads, see Managing threads. If the current position in an XML document is modified in a thread, the current position in this XML document is modified for all the threads.
