我想在过滤时检索父元素和子元素。
请找到以下 XML:
{
"store": {
"book": [
{
"category": "reference",
"author": "Nigel Rees",
"title": "Sayings of the Century",
"price": 8.95
},a
{
"category": "fiction",
"author": "Evelyn Waugh",
"title": "Sword of Honour",
"price": 12.99
},
{
"category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-553-21311-3",
"price": 8.99
},
{
"category": "fiction",
"author": "J. R. R. Tolkien",
"title": "The Lord of the Rings",
"isbn": "0-395-19395-8",
"price": 22.99
}
],
"bicycle": {
"color": "red",
"price": 19.95
}
},
"expensive": 10
}
当我给出下面的表达式时,它只给出子元素作为输出:
Expression:
$.store.book[?(@.category== 'fiction')]
Output:
[
{
"category" : "fiction",
"author" : "Evelyn Waugh",
"title" : "Sword of Honour",
"price" : 12.99
},
{
"category" : "fiction",
"author" : "Herman Melville",
"title" : "Moby Dick",
"isbn" : "0-553-21311-3",
"price" : 8.99
},
{
"category" : "fiction",
"author" : "J. R. R. Tolkien",
"title" : "The Lord of the Rings",
"isbn" : "0-395-19395-8",
"price" : 22.99
}
]
预期输出应该是:
{
"store": {
"book": [ then the below elements
[
{
"category" : "fiction",
"author" : "Evelyn Waugh",
"title" : "Sword of Honour",
"price" : 12.99
},
{
"category" : "fiction",
"author" : "Herman Melville",
"title" : "Moby Dick",
"isbn" : "0-553-21311-3",
"price" : 8.99
},
{
"category" : "fiction",
"author" : "J. R. R. Tolkien",
"title" : "The Lord of the Rings",
"isbn" : "0-395-19395-8",
"price" : 22.99
}
]
请帮助我使用 java 和代码片段的任何替代方案。
