if it is pdf we can download using following code

 Pagereference pg = new Pagereference(url); 
                    Blob b = pg.getContentAsPDF(); //Here you can use getContent() too for another type of file
                    Attachment att = new Attachment(Name = extractedString, Body = b, ContentType = 'application/pdf', ParentId='a3KDx000000TXxBMAW');
                    insert (att);
If it is other than pdf like docx, image, recording etc etc. file is being inserted but it has nothing. Thanks in advance any help will be appreciated.

Hi

I have a url which contains xml file, if i click the click the url it will download the file to my local drive, instead of doing it manually i need to achieve this using apex class, i.e. the scheduled apex class download the file from a url and upload it to the custom object.

How to achieve this, anybody have worked this kind of scenario.

thanks
Dinesh
