json串转化成xml文件、xml文件转换成json串

1.json串转化成xml文件

p=[{"name":"tom","age":30,"sex":"男"},    {"name":"lily","age":23,"sex":"女"},    {"name":"joy","age":40,"sex":"女"}]

import xml.dom.minidom

doc=xml.dom.minidom.Document()

root=doc.createElement("class")

root.setAttribute("no","1")

doc.appendChild(root)

for i in p:

student=doc.createElement("student")

name=doc.createElement("name")

name.appendChild(doc.createTextNode(i["name"]))

age=doc.createElement("age")

age.appendChild(doc.createTextNode(str(i["age"])))

sex=doc.createElement("sex")

sex.appendChild(doc.createTextNode(i["sex"]))

student.appendChild(name)

student.appendChild(age)

student.appendChild(sex)

root.appendChild(student)

fp=open(r"e:\abc\new1.xml","w")

doc.writexml(fp,indent="",addindent="\t",newl="\n",encoding="utf-8")

2.xml文件转换成json串：

方法一：

from xml.dom.minidom import parse

DOMTree=parse(r"e:\abc\new1.xml")

root=DOMTree.documentElement

print root

list_students=[]

for student in root.getElementsByTagName("student"):

d={}

for i in range(1,len(student.childNodes)-1,2):

d[student.childNodes[i].tagName]=student.childNodes[i].childNodes[0].data

list_students.append(d)

print list_students

方法二：

try:

import xml.etree.cElementTree as ET

except ImportError:

import xml.etree.ElementTree as ET

tree=ET.ElementTree(file="e:\\abc\\new1.xml")

root=tree.getroot

print root

list_students=[]

for elem in tree.iter(tag="student"):

d={}

for e in tree.iterfind("student/"):

d[e.tag]=e.text

list_students.append(d)

print list_students
