将本文件夹内的所有json文件转换为xml文件
小工具:用于将本文件夹下的所有json文件转换为xml文件。
环境:linux环境(若环境为windows会报“decode”错误,在打开文件时选择windows环境下的编码格式:GBK)
参考:python:json转xml
上代码
import os
from json import loads
from dicttoxml import dicttoxml
from xml.dom.minidom import parseString
def jsonToXml(json_path, xml_path):
#@abstract: transfer json file to xml file
#json_path: complete path of the json file
#xml_path: complete path of the xml file
with open(json_path,'r',encoding='UTF-8')as json_file:
load_dict=loads(json_file.read())
#print(load_dict)
my_item_func = lambda x: 'Annotation'
xml = dicttoxml(load_dict,custom_root='Annotations',item_func=my_item_func,attr_type=False)
dom = parseString(xml)
#print(dom.toprettyxml())
#print(type(dom.toprettyxml()))
with open(xml_path,'w',encoding='UTF-8')as xml_file:
xml_file.write(dom.toprettyxml())
def json_to_xml(json_dir, xml_dir):
#transfer all json file which in the json_dir to xml_dir
if(os.path.exists(xml_dir)==False):
os.makedirs(xml_dir)
dir = os.listdir(json_dir)
for file in dir:
file_list=file.split(".")
if(file_list[-1] == 'json'):
jsonToXml(os.path.join(json_dir,file),os.path.join(xml_dir,file_list[0]+'.xml'))
if __name__ == '__main__':
#transfer json files in current directory
j_dir = os.getcwd()
x_dir = os.getcwd()
json_to_xml(j_dir, x_dir)
- os.getcwd() 用于获取当前路径;
- file_list[-1] 用于获取文件的后缀;
- dom.toprettyxml()用于将str修改为更美观的格式
- dicttoxml用于将字典转换为xml
