[英]writing xml data to file using python
I need to write the xml i get from the function below to a file. 我需要将我从下面的函数获取的xml写入文件。 Can someone help me finish this code:
有人可以帮我完成以下代码:
import json
import urllib
results = json.load(urllib.urlopen("http://www.kimonolabs.com/api/4v1t8lgk?apikey=880a9bdbfb8444e00e2505e1533970a7"))
def json2xml(json_obj, line_padding=""):
result_list = list()
json_obj_type = type(json_obj)
if json_obj_type is list:
for sub_elem in json_obj:
result_list.append(json2xml(sub_elem, line_padding))
f= open('tori_json.xml', 'w')
f.write(str(json_obj))
f.close()
return "\n".join(result_list)
if json_obj_type is dict:
for tag_name in json_obj:
sub_obj = json_obj[tag_name]
result_list.append("%s<%s>" % (line_padding, tag_name))
result_list.append(json2xml(sub_obj, "\t" + line_padding))
result_list.append("%s</%s>" % (line_padding, tag_name))
return "\n".join(result_list)
return "%s%s" % (line_padding, json_obj)
So when i run the function json2xml(results) it would write the xml to file. 因此,当我运行函数json2xml(results)时,它将xml写入文件。
with open("data.xml",'w') as f:
for line in json2xml(results):
f.write(line.encode('utf-8'))
probably better using some xml processing lib 使用一些xml处理库可能更好
This code uses BeautifulSoup . 此代码使用BeautifulSoup 。 The JSON structure needs a little extra information for it to be a decent XML, so I added some 'product' tags to encapsulate each product.
JSON结构需要一些额外的信息才能使其成为一个体面的XML,因此我添加了一些“产品”标签来封装每个产品。

else:

return olist

top_tag.insert(len(top_tag), cur_tag)

else:

top_tag.insert(len(top_tag), cur_str)
nested = dict_recurse(results, results)
soup = BeautifulStoneSoup()
tag_tree_build(nested, soup, soup)
file("finnish.xml", "w").write(soup.prettify())
file("finnish.json", "w").write(json.dumps(results, sort_keys = True, indent = 4))
