有这样一组JSON字符串:
json_str = '''
{
"school": {
"students": [
{
"name": "小明",
"age": 12,
"sex": "male"
},
{
"name": "小红",
"age": 13,
"sex": "female"
},
{
"name": "小强",
"age": 14,
"sex": "male"
}
],
"school_name": "光明中学",
"manager": "大强",
"age": 100
}
}
'''
如果您需要获取所有学生的年龄,您是不是会用【import json】或者其他JSON库解析此JSON字符串呢,现在有种更简单的方式了呦~
首先,安装UniversalParser:
pip install UniversalParser
继续上面的代码:
import UniversalParser as UP
# json_data 是 JSON 字符串
manager = UP.parse_json(json_data, analysis_text=False)
# 获取所有学生的年龄
students_age = manager | 'students' | 'age'
print([_age & UP.SM.text for _age in students_age]) # [12, 13, 14]
# 获取学校的年龄
print(manager.document.school.age) # 100
# 遍历所有的学生
for stu in manager | 'students':
print(stu.name, stu.age, stu.sex)
''' output:
小明 12 male
小红 13 female
小强 14 male
'''
manager.save_as_xml() # 保存为 XML
