JsonDocumentPath is a class library to extract values from JSON (System.Text.Json.JsonDocument) with single line expressions

The JsonPath parser is based on the Newtonsoft.Json

NuGet Package

 string json = @"{
 ""persons"": [
 {
 ""name"" : ""John"",
 ""age"": ""26""
 },
 {
 ""name"" : ""Jane"",
 ""age"": ""2""
 }
 ]
 }";
var models = JsonDocument.Parse(json);
var results = models.SelectElements("$.persons[?(@.age > 3)]").ToList();

• ArrayIndexFilter
• ArrayMultipleIndexFilter
• ArraySliceFilter
• FieldFilter
• FieldMultipleFilter
• QueryFilter
• QueryScanFilter
• RootFilter
• ScanFilter
• ScanMultipleFilter

• JPathParseTests
• QueryExpressionTests
