Remarks

Handling elements in the XML code

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

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.
