de.wwu.scdh.saxon.harden.HardenedUnparsedTextResolver

All Implemented Interfaces:

net.sf.saxon.lib.UnparsedTextURIResolver

public class HardenedUnparsedTextResolver
extends net.sf.saxon.lib.StandardUnparsedTextResolver

Based on StandardURIResolver, this resolver restricts the access to the local file system by using a FilesystemFilter.

The allowed locations are set from a system property or an environment variable, which define a list of paths. The name of the system property is FileSystemFilter.PROPERTY. The name of the environment variable is FilesystemFilter.ENVIRON. Paths are separated by FilesystemFilter.SEPARATOR.

Configuration errors result in an empty set of allowed paths, but will be notified on stderr.

~ can be used to point to the user's home directory.
