[XML-SIG] pulldom CHARACTERS problem

[Grant Morganryuuguu]

I solved the problem and am responding to myself for the benifit of future googlers.
The sax parsers my split nodes of type CHARACTERS into multiple nodes so they have to be joined back together. Since pulldom depends on a sax parser it also may do this.  My method to find and join together the next CHARACTERS node is below. It assumes that
self.event,self.node  = iter.next()
was executed previously.

     def getCharacterNode(self,iter):
         while self.event != 'CHARACTERS':
             self.event,self.node  = iter.next()
         chars=[]
         chars.append(self.node.nodeValue)
         self.event,self.node  = iter.next()
         while self.event == 'CHARACTERS':
             chars.append(self.node.nodeValue)
             self.event,self.node  = iter.next()
         return ''.join(chars)

Cheers,
Grant

I though maybe it was related a buffering problem but this only a 4 character string. I tried changing the buffering to line buffering-- parse(inFile,None,1) --as the phrase <key>Name</key> always occurs on one line, this had no affect.
