47 | * If the main xml entity does not exist, we need to get the error handling for that
|
---|
48 | * inside the main XMLScanner::scanDocument() try block so that it gets reported
|
---|
49 | * in the normal way. We have to add a little extra safety code because, when this
|
---|
50 | * happens, there is no reader on the reader stack to get position ino from.
