Whilst experimenting with the Python bindings I noticed that exceptions
are not propagated when using registerErrorHandler(). If I run the
following I get the error message:
/etc/passwd : failed to parse.
However, there is no Traceback for the "raise". Is this correct?
import libxml2
import sys
def callback(ctx, str):
print str
raise ("How come I don't see this exception: " % str)
libxml2.registerErrorHandler (callback, "!!!")
def processNode(reader):
print "%d %d %s %d" % (reader.Depth(), reader.NodeType(),
reader.Name(), reader.IsEmptyElement())
def streamFile(filename):
try:
reader = libxml2.newTextReaderFilename(filename)
reader.SetParserProp(libxml2.PARSER_DEFAULTATTRS, 1)
reader.SetParserProp(libxml2.PARSER_VALIDATE, 1)
except:
print "unable to open %s" % (filename)
return
ret = reader.Read()
while ret == 1:
processNode(reader)
ret = reader.Read()
if ret != 0:
print "%s : failed to parse" % (filename)
sys.exit (1)
if reader.IsValid() != 1:
print "Document failed to validate"
sys.exit(1)
streamFile ("/etc/passwd")
