我们正在使用一个使用jayway库来评估
JSONpath表达式的工具.
Javascript似乎不适用它.在这种情况下,如何在JSONPath中使用正则表达式.例如,在下面的示例中,我想过滤其标题中包含“Sword”一词的所有书名：
{
"store": {
"book": [
{
"category": "reference","author": "Nigel Rees","title": "Sayings of the Century","price": 8.95
},{
"category": "fiction","author": "Evelyn Waugh","title": "Sword of Honour","price": 12.99
},"author": "Herman Melville","title": "Moby Dick","isbn": "0-553-21311-3","price": 8.99
},"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
}
解决方法
Jayway implementation使用Ruby正则表达式运算符：
$.store.book[?(@.title =~ /^.*Sword.*$/)]
忽略大小写：
$.store.book[?(@.title =~ /^.*sword.*$/i)]
