In one of my web projects the user has the option to upload
XML file. In some cases the
XML file could link to
XSD files, which means that the
XSD files have to be uploaded too. But the web browsers (as far as I know) give access only to the selected in the file chooser files so I can't automatically upload the needed files (if they are not selected).
What is the best practice to handle this situation when the multiple file selection is obligatory, but the technology (I mean the browser) can't be configured?
