[issue22750] xmlapp.py display bug when validate XML by DTD

[Ferdinand]

Ferdinand added the comment:

I found a solution :

from xml.sax import make_parser
from xml.sax.handler import feature_namespaces, feature_validation
from xml.sax.handler import ContentHandler, ErrorHandler, DTDHandler

With the library above, they is no display bug !

[issue22750] xmlapp.py display bug when validate XML by DTD

[Ferdinand]

New submission from Ferdinand:

Code is working, but the TEXT variable is not showing the correct line of the 
XML file but the the line after correct one :

Exemple :
[u6v7mr@vl-a-txx-05 Python]$ ./validateXML.py DTD/herve.xml DTD/Tomcat.dtd
ERROR: 'I' is not an allowed value for the 'value' attribute at 
DTD/herve.xml:3:19
TEXT: '
  tomcat'
XML file is KO
[u6v7mr@vl-a-txx-05 Python]$

The line expected is  :   env value=I/

The corresponding line in the DTD file is this one :
!ATTLIST env
value (D|F|R|P|Q|A) #REQUIRED


Here is the python's content :
[u6v7mr@vl-a-txx-05 Python]$ cat validateXML.py
#!/usr/bin/python

from xml.parsers.xmlproc import xmlproc
from xml.parsers.xmlproc import xmlval
from xml.parsers.xmlproc import xmldtd

def validate_xml(xml_filename, dtd_filename):
Validate a given XML file with a given external DTD.
If the XML file is not valid, an exception will be
printed with an error message.
dtd = xmldtd.load_dtd(dtd_filename)
parser = xmlproc.XMLProcessor()
parser.set_application(xmlval.ValidatingApp(dtd, parser))
parser.dtd = dtd
parser.ent = dtd
try :
parser.parse_resource(xml_filename)
except :
print XML file is KO
return 0
print XML file is OK

if __name__ == __main__:
import sys
xml_filename, dtd_filename = sys.argv[1], sys.argv[2]
validate_xml(xml_filename, dtd_filename)
[u6v7mr@vl-a-txx-05 Python]$


Here is the XML file with the error for the element env :
[u6v7mr@vl-a-txx-05 Python]$ cat DTD/herve.xml
?xml version='1.0' encoding='utf-8'?
config
  env value=I/
  tomcat count=1 start=1 step=1 adresseIP=10.108.250.72 offset=10

[u6v7mr@vl-a-txx-05 Python]$
Here is the stdout expected :
[u6v7mr@vl-a-txx-05 Python]$ ./validateXML.py DTD/herve.xml DTD/Tomcat.dtd
ERROR: 'I' is not an allowed value for the 'value' attribute at 
DTD/herve.xml:3:19

XML file is KO
