Python抛出ascii编解码器无法编码u'\x'；第108位：解析xml时序号不在范围（128）内错误

python xml

Python抛出ascii编解码器无法编码u'\x'；第108位：解析xml时序号不在范围（128）内错误,python,xml,Python,Xml,我用Python运行了以下代码： import xml.etree.ElementTree as ET tree = ET.parse('dblp_140.xml') root = tree.getroot() f = open('hi', 'w') for country in root.findall('article'): rank = country.find('year').text name = country.find('title') if(int(ra

我用Python运行了以下代码：

import xml.etree.ElementTree as ET
tree = ET.parse('dblp_140.xml')
root = tree.getroot()
f = open('hi', 'w')
for country in root.findall('article'):
    rank = country.find('year').text
    name = country.find('title')

    if(int(rank)>2009):
        f.write(name.text)
        f.write(':')
        auth = country.findall('author')
        for a in auth:
            #print str(a)
            f.write(a.text.encode('utf8'))  
            f.write(',')
        f.write('\n')

我在位置108:ordinal不在范围（128）中遇到一个错误，ascii编解码器无法对u'\x'进行编码。我试图分析dblp数据，如下所示：

该文件比我发布的文件大。如何解决它？

StackOverflow将XML文件的编码弄乱了，因此我无法真正测试这一点，但请尝试以下方法：

import xml.etree.ElementTree as ET

parser = ET.XMLParser(encoding="iso-8859-1")
parser.parser.UseForeignDTD(True)
etree = ET.ElementTree()

tree = etree.parse('dblp_140.xml', parser=parser)

f = open('hi', 'w')
for country in tree.findall('article'):
    rank = country.find('year').text
    name = country.find('title')

    if(int(rank)>2009):
        f.write(name.text)
        f.write(':')
        auth = country.findall('author')
        for a in auth:
            print a.text.encode('utf-8')
            f.write(a.text.encode('utf-8'))  
            f.write(',')
        f.write('\n')

将

f.write（a.text.encode（'utf8'））

更改为

f.write（a.text）

；它已经是UTF-8了。您使用的是哪个python版本？我正在使用python 2.7。任何其他错误都会出现。例如：u'\03b1'，u'\xe8'，u'\xe9'，等等。请帮助。请显示完整的堆栈跟踪，并说明错误发生在哪一行。将

f.write（a.text.encode（'utf8'）

更改为

f.write（a.text）
