根据属性分解/合并数组

我有一个通过组合其他两个数组构成的数组。新数组具有基于属性（id）连接的原始数组中的所有数据。我想制作一个新数组，将所有属性（id）值组合到一个字符串中，而无需复制数据。数据具有许多不同的（属性和属性值）对，但其余数据相同。这是两个数据示例：

    0:
    id: "00ABCD-0003"
    AccessionID: "UWAR_007_Test"
    Attribute: "Object Type"
    AttributeValue: "Glass"
    BoxNumber: "2000"
    CatalogDate: null
    Cataloger: "rkirkwo2@uwyo.edu"
    FSNumber: null
    FreeformValue: null
    ProjectNumber: "#154 WAPA"
    SiteID: "00ABCD"
    Units: null

    1:
    id: "00ABCD-0003"
    AccessionID: "UWAR_007_Test"
    Attribute: "Glass Material Type"
    AttributeValue: "Aluminosilicate glass"
    BoxNumber: "2000"
    CatalogDate: null
    Cataloger: "rkirkwo2@uwyo.edu"
    FSNumber: null
    FreeformValue: null
    ProjectNumber: "#154 WAPA"
    SiteID: "00ABCD"
    Units: null

以下是完整数据数组。谢谢你的帮助！

数据将被用于打印出博物馆的标签，以便将其放入存放文物的袋子中。因此，我需要能够获得的所有数据而无需重复任何操作。

例如，我想看看：

    id: "00ABCD-0003"
    AccessionID: "UWAR_007_Test"
    Attribute: "Object Type"
    AttributeValue: "Glass"
    Attribute: "Glass Material Type"
    AttributeValue: "Aluminosilicate glass"
    BoxNumber: "2000"
    CatalogDate: null
    Cataloger: "rkirkwo2@uwyo.edu"
    FSNumber: null
    FreeformValue: null
    ProjectNumber: "#154 WAPA"
    SiteID: "00ABCD"
    Units: null

答案 0 :(得分：0)

在这种情况下，您需要使用不同的ID过滤数组。
