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 find out the error details, use ErrorInfo.
<XML document>: Character string (with quotes)

Remarks

Handling elements in the XML code

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

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. See Managing threads for more details.
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.
