How to open all files (eg *.xml) in batch in a folder ???

Hi ALL,

I have an question about open files in Navision. I have a Codeunit which used to import XMLport.

TestFile.OPEN('C:\Output\PO1.xml');
TestFile.CREATEINSTREAM(TestStream);
XMLPORT.IMPORT(50003,TestStream);

Besides PO1.xml, there are also other xml eg PO2.xml, PO3.xml, etc in the Output folder. And what I want to do is to import all *.xml files in the Output folder to Navision, but I don't know exactly how many xml files will be in the folder and the file names of each files. I want to make this codeunit to be able to open and read all the xml file in the Output folder so that I can put this Codeunit in the Job Scheduler and let it run regularly.

Does anyone have some ideas?
