Examples of net.sf.saxon.s9api.XdmSequenceIterator

net.sf.saxon.s9api.XdmSequenceIterator
An iterator over an XPath sequence.
This class implements the standard Java Iterator interface.

Because the Iterator interface does not define any checked exceptions, the hasNext() method of this iterator throws an unchecked exception if a dynamic error occurs while evaluating the expression. Applications wishing to control error handling should take care to catch this exception.
