A saxon:break instruction causes early exit from a loop defined using
saxon:iterate. The instruction must appear lexically within
the saxon:iterate element.
If the saxon:iterate instruction takes its input from streamed document (using
the saxon:stream() function) then executing saxon:break will cause
the parsing and analysis of that document to terminate. This can be very useful when you only want
to examine a small amount of data near the start of a large document. Note however that it means that
any well-formedness or validity errors appearing later in the source document will not be detected.
For further details and examples see saxon:iterate.
This instruction is available in Saxon-EE only
