我有很多結構不同的 javascript 代碼，但在每個 js 代碼中，都有多個結構相似的 json。
我只想決議那些有鍵的物件"@context": "https://schema.org",
我已經寫了這個模式，但它用一些 javascript 代碼匹配了 joson。我只想抓取 json 物件，僅此而已。有人可以幫我嗎？
(\{\s\S\@context\"\:\s\"https\:\//schema\.org\"\,[\s\S] )
在這里，您可以使用示例代碼：

<div data-location="page-fo
它應該像這樣匹配所有物件：
{
"@context": "https://schema.org",
"@type": "Car",
"description": document.head.querySelector("[name=description]") ? document.head.querySelector("[name=description]").content : "",
"vehicleModelDate": "2015",

"sku": "08c765ea0a0e0a922cefdf66496c54cd",

"itemCondition": "used",
"url": location.origin location.pathname,
"vehicleIdentificationNumber": "3C6RR7LT1FG710130",
"fuelEfficiency": ["16","23"],
"driveWheelConfiguration":"4x4",
"vehicleEngine": "V-8 cyl",
"color": "Bright White",
"vehicleInteriorColor": "Diesel Gray/Black",
"fuelType": "Regular Unleaded",
"mileageFromOdometer": "60455",
"vehicleTransmission": "8 speed automatic",
"name": "Ram 1500 Truck Crew Cab",
"image": "https://images.dealer.com/autodata/us/large_stockphoto-color/2015/USC50RMT11CB0/PW7.jpg",
"offers": {
"@type": "Offer",
"priceCurrency": "USD",
"price": "31000.0",
"availability": "http://schema.org/InStock"
}
};
會有多個具有相同字串的物件，我想匹配所有物件，有人可以幫忙嗎？
uj5u.com熱心網友回復：
與大多數正則運算式問題一樣，您必須做出一些（盡管受過教育）猜測。假設：
- json 物件以分號結尾
- 中間沒有任何懸空的分號（幾乎永遠不會出現這種情況）
那么這應該作業：
r".*(\{.*?[\'\"]@context[\'\"]\s*:\s*[\'\"]https://schema\.org[\'\"].*?\}(?=[\n\r\s]*;\s*[\n\r])).*"
使用如下：
# src = the entire input
regex = r".*(\{.*?[\'\"]@context[\'\"]\s*:\s*[\'\"]https://schema\.org[\'\"].*?\}(?=[\n\r\s]*;\s*[\n\r])).*"
print(re.findall(regex, src, flags=re.DOTALL)[0])
這給了我：
{
"@context": "https://schema.org",
"@type": "Car",
"description": document.head.querySelector("[name=description]") ? document.head.querySelector("[name=description]").content : "",
"vehicleModelDate": "2015",
"manufacturer": "Ram",
"model": "1500",
"sku": "08c765ea0a0e0a922cefdf66496c54cd",
"bodyType": "Truck Crew Cab",
"itemCondition": "used",
"url": location.origin location.pathname,
"vehicleIdentificationNumber": "3C6RR7LT1FG710130",
"fuelEfficiency": ["16","23"],
"driveWheelConfiguration":"4x4",
"vehicleEngine": "V-8 cyl",
"color": "Bright White",
"vehicleInteriorColor": "Diesel Gray/Black",
"fuelType": "Regular Unleaded",
"mileageFromOdometer": "60455",
"vehicleTransmission": "8 speed automatic",
"name": "Ram 1500 Truck Crew Cab",
"image": "https://images.dealer.com/autodata/us/large_stockphoto-color/2015/USC50RMT11CB0/PW7.jpg",
"offers": {
"@type": "Offer",
"priceCurrency": "USD",
"price": "31000.0",
"availability": "http://schema.org/InStock"
}
}
解釋
由于逐個解釋這個標記太復雜并且實際上沒有幫助，我將在這里解釋重要的部分：
[\'\"]處理使用的任何型別的引號
(?=[\n\r\s]*;\s*[\n\r])確保物件后跟一定數量的換行符或空格，然后是分號，然后是換行符（基本上，它應該是 JS 運算式的結尾）
re.DOTALL確保點運算子匹配所有內容，包括換行符
