【问题描述】：

这是来自this SO question 的后续问题。

现在已经从 here 找到的演示链接库创建了模型结构，我现在想提取事实表信息。

模型结构为：

us-gaap_IncomeStatementAbstract

Statement [Table]                                           us-gaap_StatementTable

我试图从 xml 文档重新创建的事实表包含以下信息：

然后可以渲染这个事实表来生成这个表：

问题是我不确定如何获取每个订单项的具体事实。例如，模型结构包含元素Net sales，其概念为us-gaap_SalesRevenueNet。 instance document 包含对us-gaap_SalesRevenueNet 的以下引用：

在显示的 12 个事实中，事实表只需要两个事实 - 它们是 contextRef 为 eol_PE2035----1510-Q0015_STD_91_20141227_0 和 eol_PE2035----1510-Q0015_STD_91_20151226_0 的事实。

这些 contextRef id 对应于实例文档中的以下事实：

<context id="eol_PE2035----1510-Q0015_STD_91_20141227_0">
<entity>
<identifier scheme="http://www.sec.gov/CIK">0000320193</identifier>
</entity>
<period>
<startDate>2014-09-28</startDate>
<endDate>2014-12-27</endDate>
</period>
</context>

<context id="eol_PE2035----1510-Q0015_STD_91_20151226_0">
<entity>
<identifier scheme="http://www.sec.gov/CIK">0000320193</identifier>
</entity>
<period>
<startDate>2015-09-27</startDate>
<endDate>2015-12-26</endDate>
</period>
</context>

这些 contextRef 本质上是 Period Axis 元素。我无法判断周期轴是如何从 xml documents 确定的，因此无法重现事实表。任何人都可以阐明如何做到这一点？

标签： xml xbrl edgar

【解决方案1】：

您粘贴的是简化的呈现，而不是收入报表的完整呈现。

完整的渲染是：

您可以从definition linkbase 中获取该信息：

例如，您列出的 SalesRevenueNet 之一链接到上下文“eol_PE2035----1510-Q0015_STD_91_20141227_0_1106947x1173722”。此上下文包含对轴“us-gaap:StatementBusinessSegmentsAxis”的限制。因此，该上下文在 StatementOfIncome 之外，因为该轴未在相应定义链接库的超立方体中定义。

我假设您这样做是为了学习？否则，我建议您使用 secxbrl.info 之类的服务：

Factable as a list (JSON)（也可以获取csv、html、xml）
Factable as a rendered table (JSON)（也可以获取html）
