Syntax

<Result> = XMLRoot(<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

After XMLRoot, the current element can be handled by XMLElementName, XMLParentName, XMLElementType and XMLData.

Using XMLRoot during a search

If a search is in progress (XMLFind), XMLRoot 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.
