I'm lost here.. I can't find anything called PrintVisitor or
PrettyPrintVisitor in any of the PyXML Code :

reza@gooz:/usr/local/src/PyXML-0.5.4 > find . -type f -print | xargs
grep -i NameNodeMap
reza@gooz:/usr/local/src/PyXML-0.5.4 > find . -type f -print | xargs
grep -i PrettyPrintVisitor
reza@gooz:/usr/local/src/PyXML-0.5.4 > find . -type f -print | xargs
grep -i PrintVisitor
reza@gooz:/usr/local/src/PyXML-0.5.4 >

I tried to specify pyexpat as the parser :

-------------
from xml.dom import core, utils
import sys

fr = utils.FileReader()
path = sys.argv[1]
file = open(path, 'r')
document = fr.readXml(file, 'pyexpat')
print document.toxml()

and I got this exception thrown :

---------------
# /lc/bin/python /tmp/test.py /var/tmp/JUNIPER.xml 
Traceback (innermost last):
  File "/tmp/test.py", line 7, in ?
    document = fr.readXml(file, 'pyexpat')
  File "/lc/blackshadow/PyXML/xml/dom/utils.py", line 162, in readXml
    p = saxexts.make_parser(parserName)
  File "/lc/blackshadow/PyXML/xml/sax/saxexts.py", line 159, in make_parser
    return XMLParserFactory.make_parser(parser)
  File "/lc/blackshadow/PyXML/xml/sax/saxexts.py", line 65, in make_parser
    raise saxlib.SAXException("No parsers found",None)
xml.sax.saxlib.SAXException: No parsers found
-------------

Am I doing something wrong?

Thanks,
