XMLChild (Function) In french: XMLFils Positions on the first child element of current element. To select an element, use the functions for XML search and browse ( XMLFirst, XMLLast, ...). Reminder: An element is either a tag or an attribute.
// Create the XML document
XMLDocument("XMLOrd", SourceMyXML)
// Browse performed by XMLFirst and XMLNext
// Positions on "<order>" element
XMLFirst("XMLOrd")
// Goes one level down and positions on "<number>" element
XMLChild("XMLOrd")
// Retrieves the order number
OrdNum is int = Val(XMLData("XMLOrd")) // contains 1
Syntax
<Result> = XMLChild(<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 Remark: you can use XMLExtractDocument to read only the content of a tag and be notified when you've reached the end with XMLOut. Using XMLChild during a search If a search is in progress ( XMLFind), XMLChild cancels this search. 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.
