xml - AttributeError : type object 'ElementTree' has no attribute 'tostring'

我有这个问题AttributeError: type object 'ElementTree' has no attribute 'tostring'，我不知道怎么了，我导入到字符串，这是行不通的。
尝试遵循另一个教程，但是什么也没有。

还有其他方法可以将ElementTree对象转换为XML字符串吗？

import os
import re
import glob
from xml.dom import minidom
from time import strftime
from xml.etree.ElementTree import ElementTree
from xml.etree.ElementTree import Element, SubElement, Comment, tostring
date=strftime("%Y-%m-%dT%H:%M:%S")
os.chdir('/home/guillermo/TclsPy/XML_Level2/')

def prettify(elem):
    """Return a pretty-printed XML string for the Element.
    """
    rough_string = ElementTree.tostring(elem, 'utf-8',method="xml" ,     short_empty_elements=True)
    reparsed = minidom.parseString(rough_string)
    return reparsed.toprettyxml(indent=" ")





for nameXml in glob.glob("*.xml"):
    new_nameXml = re.sub(r'tlmy',r'AUX',nameXml,flags=re.IGNORECASE)
    new_nameXml = re.sub('.xml','_AlarmEnabled.xml',new_nameXml, flags=re.IGNORECASE)#new_nameXml.lower().replace('.xml','_AlarmEnabled.xml')
    match = re.search(r'TSL_TM_TLMY_(.+).xml', nameXml,flags= re.IGNORECASE )
    if match:
        #Si matchea el patron, guardamos en subsistema lo que esta entre ()
        subsistema = match.group(1)
        print "Nombre:", new_nameXml
        print "Subsistema:", subsistema
    else:
        print "No matchea:", nameXml
       # raw_input()
    #<?xml version="1.0" encoding="UTF-8"?>
    TSLFunction=Element('TSLFunction')
    child = SubElement(TSLFunction, 'unit')
    child.text = '<![CDATA[AUX]]>'

    child1= SubElement(TSLFunction,'mnemonic')
    child1.text='<![CDATA'+'['+'AUX::'+'AUX.'+subsistema.replace('.xml','')+'_AlarmEnabled]]'

    child2=SubElement(TSLFunction, 'body')
    child2.text='<![CDATA[out = true;]]>'

    child3=SubElement(TSLFunction,'description')
    child3.text='<![CDATA[--]]>'

    child4=SubElement(TSLFunction,'name')
    child4.text='<![CDATA['+subsistema+'_AlarmEnabled'+']]'

    child5=SubElement(TSLFunction,'minorVersion')
    child5.text='0'

    child6=SubElement(TSLFunction,'majorVersion')
    child6.text='1'

    child7=SubElement(TSLFunction,'lastUpdate')
    child7.text=date

    child8=SubElement(TSLFunction,'creationDate')
    child8.text=date

    child9=SubElement(TSLFunction,'checked')
    child9.text='false'

    returnchild=SubElement(TSLFunction,'return')


    name=SubElement(returnchild,'name')
    name.text='<![CDATA[out]]>'

    returnType=SubElement(returnchild,'returnType')
    returnType.text='boolean'
    label=SubElement(returnchild,'label')
    label.text='<![CDATA[--]]>'

    parameters=SubElement(TSLFunction,'parameters')

    subtype=SubElement(TSLFunction,'subtype')
    subtype.text='<![CDATA[TM]]>'

    prefix=SubElement(TSLFunction,'prefix')
    prefix.text='<![CDATA[AUX]]>'

    variable=SubElement(TSLFunction,'variable')
    variable.text='<![CDATA['+subsistema +'_AlarmEnabled]]'
    print (subsistema)

    tree = ElementTree(prettify(TSLFunction))
    tree.write('../Alarm/'+new_nameXml)enter code here

最佳答案

xml.etree.ElementTree.ElementTree类没有tostring方法。它是xml.etree.ElementTree模块中的一个函数。

您已经从代码中的模块中导入了tostring。改变

rough_string = ElementTree.tostring(elem, 'utf-8', method="xml", short_empty_elements=True)

至

rough_string = tostring(elem, 'utf-8', method="xml")

它应该工作。
short_empty_elements参数仅在Python 3.4中可用。它在Python 2.7中不起作用。
