python sax error "junk after document element"
I use python sax to parse xml file. The xml file is actually a combination of multiple xml files. It looks like as follows:
<row name="abc" age="40" body="blalalala..." creationdate="03/10/10" />
<row name="bcd" age="50" body="blalalala..." creationdate="03/10/09" />
My python code is in 开发者_如何学编程the following. It show "junk after document element" error. Any good idea to solve this problem. Thanks.
from xml.sax.handler import ContentHandler
from xml.sax import make_parser,SAXException
import sys
class PostHandler (ContentHandler):
def __init__(self):
self.find = 0
self.buffer = ''
self.mapping={}
def startElement(self,name,attrs):
if name == 'row':
self.find = 1
self.body = attrs["body"]
print attrs["body"]
def character(self,data):
if self.find==1:
self.buffer+=data
def endElement(self,name):
if self.find == 1:
self.mapping[self.body] = self.buffer
print self.mapping
parser = make_parser()
handler = PostHandler()
parser.setContentHandler(handler)
try:
parser.parse(open("2.xml"))
except SAXException:
xmldata = '''
<row name="abc" age="40" body="blalalala..." creationdate="03/10/10" />
<row name="bcd" age="50" body="blalalala..." creationdate="03/10/09" />
'''
Add a wrapper tag around the data. I've used ElementTree since it's so simpler, but you'd be able to do the same on any parser:
from xml.etree import ElementTree as etree
# wrap the data
xmldata = '<rows>' +data + '</rows>'
rows = etree.fromstring(xmldata)
for row in rows:
print row.attrib
Results in
{'age': '40',
'body': 'blalalala...',
'creationdate': '03/10/10',
'name': 'abc'}
{'age': '50',
'body': 'blalalala...',
'creationdate': '03/10/09',
'name': 'bcd'}
Seems that you do not have root element in your XML file. Wrap your row elements into single rows element.
