该following source code工程：

from xml.parsers import expat

xmlFile = "xml.xml"


class xmlText(object):
    def __init__(self):
        self.textBuff = ""

    def CharacterData(self, data):
        data = data.strip()
        if data:
            data = data.encode('ascii')
            self.textBuff += str(data) + "\n"

    def Parse(self, fName):
        xmlParser = expat.ParserCreate()
        xmlParser.CharacterDataHandler = self.CharacterData
        xmlParser.Parse(open(fName).read(), 1)


xText = xmlText()
xText.Parse(xmlFile)
print("Text from %s\n=" % xmlFile)
print(xText.textBuff)

输出

Text from xml.xml
=
b'Hello'
b'my'
b'name'
b'is'
b'Buddy.'
b'I'
b'am a'
b'superhero'
b'.'
b'At least,'
b'I think'
b'so...:)'
b'What'
b'do you'
b'think'
b'?'
b'Let me know. :)'

但是，它会在每行文本前面添加一个字符b

我怎样才能去掉它

Answer 1

拆下线路

data = data.encode('ascii')

Answer 2

^{}

xml.parsers.expat.ParserCreate(encoding=None, namespace_separator=None)

Creates and returns a new xmlparser object. encoding, if specified, must be a string naming the encoding used by the XML data. Expat doesn’t support as many encodings as Python does, and its repertoire of encodings can’t be extended; it supports UTF-8, UTF->16, ISO-8859-1 (Latin1), and ASCII.

只需将编码传递给Parse方法内的ParserCreate函数即可

xmlParser = expat.ParserCreate(encoding='ASCII')
