Get method documentation [Android Documentation]

The system identifier, a URI reference [], for this input source. The system identifier is optional if there is a byte stream, a character stream, or string data. It is still useful to provide one, since the application will use it to resolve any relative URIs and can include it in error messages and warnings. (The LSParser will only attempt to fetch the resource identified by the URI reference if there is no other input available in the input source.)

If the application knows the character encoding of the object pointed to by the system identifier, it can set the encoding using the encoding attribute.

If the specified system ID is a relative URI reference (see section 5 in []), the DOM implementation will attempt to resolve the relative URI with the baseURI as the base, if that fails, the behavior is implementation dependent.
