Description

We have some large xml data(more than 1000 <item>s) but we only need the first 20. Is it possible to limit the number of <item>s to parse so that it will only return the first 20. This will save 80% of our computation time.

Input

Code

Output

expected data

• Only first 20 s in xml data

Currently FXP works on String where you require to read whole file contents in advance and there is no benefit to read a few items from starting. I've added it as feature request so that if we develop FXP to work on stream then this feature can be implemented.

We'll have to define some mechanism to meet the condition when to skip/stop.

There is one way to achieve it if we close all the open parent tags as soon as the limit is reached. But it can be buggy. And no doubt stream support will be required
