[Tutor] xml stuff

[Furmanek, Greg]

Ok I have used the expat stuff and I get some strange results:

Character data: [u'    ']
Start element: [PRICE] [{}]
Character data: [u'$7.06']
End element: [PRICE]
Character data: [u'\012']
Character data: [u'    ']
Start element: [AVAILABILITY] [{}]
Character data: [u'052599']
End element: [AVAILABILITY]
Character data: [u'\012']
Character data: [u'  ']
End element: [PLANT]
Character data: [u'\012']
Character data: [u'  ']
Character data: [u'\012']
End element: [CATALOG]

when parsing some stuff I get these u characters.
Is this normal. code follows:

from xml.parsers import expat




def start_element(name, attrs):
    print 'Start element: [%s] [%s]' % ( name, attrs)

def end_element(name):
    print 'End element: [%s]' % ( name )

def char_data(data):
    print 'Character data: [%s]' % ( repr(data) )

#  ...............................   FUNCTIONS
...............................
def main():

	p = expat.ParserCreate()

	p.StartElementHandler = start_element
	p.EndElementHandler = end_element
	p.CharacterDataHandler = char_data

	p.Parse( 
"""<?xml version="1.0"?>

    <BOTANICAL>Asclepias tuberosa</BOTANICAL>

</CATALOG>""")
