How do i append characters to a string?
actually my entire handler code is
class oldHandler(ContentHandler):
def __init__(self):
self.fn = 0
self.dn = 0
self.i=[]
self.x=""
self.y=""
self.z=""
self.t=0
self.xx=''
def startElement(self, name, attrs):
if name=='dirname':
self.dn=1
if name=='name':
self.fn=1
if name=='time':
self.t=1
def characters(self,str):
if self.dn:
self.x=str
if self.fn:
self.y=str
if self.t:
self.z=str
ss= self.x+'/'+self.y+','+self.z+ '\r \n'
self.i.append(ss)
def endElement(self, name):
if name == 'dirname':
self.dn=0
if name=='name':
self.fn=0
if name=='time':
self.t=0
def endDocument(self):
f=open('old.txt', 'w')
self.i.sort
f.writelines(self.i)
f.close
so my old.txt now looks like this
y+def.txt,200607130417
C:\Documents and Settings\Administrator\Desktop\1\hii
wx\abc.txt,200607130415
But i wont the output as
C:\Documents and Settings\Administrator\Desktop\1\bye
w&y\def.txt,200607130417
C:\Documents and Settings\Administrator\Desktop\1\hii
wx\abc.txt,200607130415
