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 ew1.xml","w")

doc.writexml(fp,indent="",addindent=" ",newl=" ",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 ew1.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
