AST 如下：

JSON

{
    "concept": "AnonymousFunction",
    "params": [
        {
            "concept": "Param",
            "name": "item",
            "description": ""
        }
    ],
    "body": {
        "concept": "BinaryExpression",
        "left": {
            "concept": "MemberExpression",
            "object": {
                "concept": "MemberExpression",
                "object": {
                    "concept": "Identifier",
                    "namespace": "",
                    "name": "item"
                },
                "property": {
                    "concept": "Identifier",
                    "namespace": "",
                    "name": "productReport"
                }
            },
            "property": {
                "concept": "Identifier",
                "namespace": "",
                "name": "executed"
            }
        },
        "right": {
            "concept": "NullLiteral"
        },
        "operator": "!="
    }
}

YAML

concept: AnonymousFunction
params:
  - concept: Param
    name: item
    description: ""
body:
  concept: BinaryExpression
  left:
    concept: MemberExpression
    object:
      concept: MemberExpression
      object:
        concept: Identifier
        namespace: ""
        name: item
      property:
        concept: Identifier
        namespace: ""
        name: productReport
    property:
      concept: Identifier
      namespace: ""
      name: executed
  right:
    concept: NullLiteral
  operator: "!="

对应的代码如下：

文本化 NASL

{ item: String => item.productReport.executed != null }
