Hi,
I think that that there is an encoding related bug in Xerces2.5.
When using DOM parser, and trying to parse a document that contains characters
that do not belong to the character set that correspond to the specified
document encoding (e.g. the character ä is contained in the document which
encoding is specified as "us-ascii"), the parser is crashing.
Here is the code snippet:
try {
DOMParser parser = new DOMParser();
parser.parse(toParse);
}catch (Exception ex) {
ex.printStackTrace();
}
* "toParse" is the path to the following document:
<?xml version="1.0" encoding="us-ascii"?>
<Package Id="pkg1">
<!-- ä -->
<PackageHeader>
<XPDLVersion>1.0</XPDLVersion>
<Vendor>Together</Vendor>
<Created>2003-08-20 10:00:49</Created>
</PackageHeader>
</Package>
The parser crashes because of ä character, and I get the following stack trace:
java.io.IOException: Byte "228" is not a member of the (7-bit) ASCII character
set.

When I use Xerces2.4, everything goes fine!
