The line number and column number issued by fatal error is bogus.

Key: XERCESC-1839
URL: https://issues.apache.org/jira/browse/XERCESC-1839
Project: Xerces-C++
Issue Type: Improvement
Components: DOM, SAX/SAX2, Utilities
Affects Versions: 2.7.0, 3.0.1
Environment: I ran sample program on linux 64. But it is not
platform/os/compiler dependent.
Reporter: Bin Dai
Priority: Minor
Fix For: 2.7.0, 3.0.1
The xml file (test.xml) below has two french letters (marked here as ',').
file test.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<Project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<!-- d'�t� 2008 -->
</Project>
When I ran DOMPrint test.xml or SAMPrint test.xml, the fatal errors occured and
here is the output:
DOMCount test.xml
Fatal Error at file
/home/bdai/xfndry/HEAD/env/xerces-c-3.0.0-x86_64-linux-gcc-3.4/bin/test.xml,
line 1, char 40
Message: invalid byte 't' at position 2 of a 3-byte sequence
Errors occurred, no output available
Regardless where I move the gilty line, the line number (=1)and column (=40) do
not change.
Debugging through the code, I see that XMLReader.cpp keeps track of the line
number and column number, but it calls XMLUTF8Transcoder.cpp where it peeks
each byte. When it realizes that the byte is not an UTF8 code, it throws an
exception. XMLReader never updates its line and column numbers.
If the error occurs after 4000X bytes, the line will be updated to a new line,
but will be unchanged inside the second 4K(hex) bytes regardless where the
error is.
It would be helpful to report the real line number.
