iwextattr XML Input Errors

cboyd2

Hello,

I have written a perl script to copy files/EAs from one workarea to another. To save much needed time I am using the -x option to export/import the extended attributes as an XML string. For some reason some of the files are giving me "not well-formed / Unable to parse XML input" error. Does anyone know how to avoid this error? I tried using the -u option to encode and decode as UTF8 but I am either doing it wrong or have different problem.

I am basically reading in the XML into a string, witting the XML to a file and then setting the attributes on the new file.

Here are some snippets of the code. I tired converting the string to UTF8 which did avoid the error but the double byte characters were corrupted.

###
my ($getAttrib) = $iwhome . "\\bin\\iwextattr -xu";
my ($setAttrib) = $iwhome . "\\bin\\iwextattr -s -xu";

my $Attributes = qx($getAttrib $o 2>&1);
#utf8::encode($Attributes);

open XML, ">$TempXML" or die "can not open $TempXML\n";
print XML "$Attributes\n";
close(XML);

my $SetAtt = `$setAttrib \"$n\" < $TempXML`;
###

Any help would be much appreciated!

Thanks,
-Chuck

There's a bug (IMO - though I don't know if it's been reported) in which iwextattr -s -x will not accept null or empty values (even though -l -x will generate them) - this includes ' ' (a space character).

You may need to either remove such elements from your $TempXML or use a regex to set them to something like '.'

If this is indeed the problem you are running into - please file a bug with Support on this (I meant to, but forgot and don't have a customer to do so for right now)
