[xml] xmllint: Exit code 0 despite undefined namespace prefix

[Christian Weiske <cweiske cweiske de>]

Hello,


I'm using xmllint to validate files automatically during CI runs, and 
now an error was not catched.

The xml file used a namespace prefix that was not defined. xmllint 
noticed that, but still gave an exit code of 0:

> $ xmllint --noout text.xml; echo $?
> text.xml:66: namespace error : Namespace prefix v on tag is not defined
>         <v:tag/>
>               ^
> 0

Is there a way to make xmllint use a non-0 exit code in this case?

(Happens on Ubuntu Linux 20.04:
xmllint: using libxml version 20912
   compiled with: Threads Tree Output Push Reader Patterns Writer SAXv1 
FTP HTTP DTDValid HTML Legacy C14N Catalog XPath XPointer XInclude Iconv 
ICU ISO8859X Unicode Regexps Automata Schemas Schematron Modules Debug 
Zlib Lzma
)
