Question

我有一个充满字母数字的文本文件。我正在使python脚本从每一行获取数据并追加到变量并将该变量添加到XML。 XML将文件名添加到字母数字。但是，它无法识别数据。的错误状态

 Traceback (most recent call last):
 File "./xml.py", line 13, in <module>
 fn.text = values
 File "src/lxml/etree.pyx", line 1018, in lxml.etree._Element.text.__set__
 File "src/lxml/apihelpers.pxi", line 710, in lxml.etree._setNodeText
 File "src/lxml/apihelpers.pxi", line 698, in lxml.etree._createTextNode
 File "src/lxml/apihelpers.pxi", line 1491, in lxml.etree._utf8
TypeError: Argument must be bytes or unicode, got 'list'

由于错误指出它应该是unicode，因此我添加了代码

values = base64.b64encode(values)

但是它给出了错误

Traceback (most recent call last):
 File "./xml.py", line 10, in <module>
   values = base64.b64encode(values)
 File "/usr/lib/python2.7/base64.py", line 54, in b64encode
   encoded = binascii.b2a_base64(s)[:-1]
 TypeError: b2a_base64() argument 1 must be string or buffer, not list

我尝试这样做 ''' 值= [x.encode（'utf-8'）for x in values] '''

结果显示

<FileName>['1235362363151512d12d']</FileName>

这不是我期望的。我希望结果是

<FileName>1235362363151512d12d</FileName>

#!/usr/bin/python

from lxml import etree as ET
root = ET.Element("alphanumeric")
file = open("alphanumeric.txt", "r")

for aline in file:
        values = aline.split()
        length = len(values)
        child = ET.SubElement(root,"child")

        fn = ET.SubElement(child, "FileName")
        fn.text = values
        tree = ET.ElementTree(root)
tree.write("filename.xml")

x = ET.parse("filename.xml")
print ET.tostring(x, pretty_print=True)

我希望结果是一个漂亮的XML。但是取而代之的是关于参数的错误，必须使用字节或unicode。该变量导致错误。将变量附加到xml的正确方法是什么？

您的values = aline.split()语句似乎是问题的根源。尝试以这种方式修改for循环，看看它是否有效：

for aline in file:       
    child = ET.SubElement(root,"child")
    fn = ET.SubElement(child, "FileName")
    fn.text = aline
    tree = ET.ElementTree(root)

Python无法将变量添加到XML
