控制 XML 处理中的数据流

问题描述 投票：0回答：1

我们使用 XSLT 将业务数据从 XML 映射到 XML，并且无需 Web 参与。我需要获取 XML 输入并输出相同的数据，并将某些类型的多次出现的记录合并为一个。过程语言中的简单内容却让 XSLT 难住了。

此代码就是我们现在所拥有的，除了 2 种记录类型之外，XML 的输出没有任何更改。这非常有效，我们向 E2EDT37 和 E2EDT43 记录添加了新元素。代码格式对我不起作用，所以我改为引用。

xsl:选择 xsl:否则 xsl:选择

这是数据。每个E2EDT37记录代表一个纸箱，每个E2EDT43是纸箱的内容。在最后一个 E2EDT37 中，我们有 2 个 E2EDT43 记录，当一个纸箱中有两种零件类型时，这是正常的。但在这里，我们从 E2EDT43_VBELN 和 E2EDT43_POSNR 中看到，这两种情况下都是相同的行项目。 hgave =0060088483 和 =000010 因此应该合并。

第一个 E2EDT43 显示数量 (E2EDT43_VEMNG) 为 1，第二个显示 177。因此，我们确实有一个 178 的行项目被 SAP 以某种方式分割，我需要将它们合并到一个总数量为 178 的 E2EDT43 中。

E2EDT38 不相关，可以从输出中排除或按原样复制。

我想我应该更改代码来检测包含 E2EDT37 和 E2EDT43 记录的 G07 组。我将复制 E2EDT37 并添加一些元素，就像我们现在所做的那样。然后继续复制 E2EDT38 不变，然后执行例程来检查 E2EDT43 是否需要合并并创建输出。

但是，一旦我将 G07 传递到 E2EDT37 模板，如何复制 E2EDT38，然后在 G07 中处理 E2EDT43？从模板 E2EDT37 返回后，如何恢复数据流？只是为了简单起见，E2EDT37 模板现在不执行任何操作，并且 E2EDT37_ADDITIONAL_SEG 被注释掉。

xsl:选择

下面是我现在得到的。它创建 E2EDT37 元素，但随后字段都位于连续的字符流中。在我检测到 G07 并调用模板后，我似乎失去了上下文，不知道如何解决这个问题。 E2EDT38 已创建，但 E2EDT43 完全丢失。代码示例固然很好，但了解如何使用数据流才是我真正需要学习的。任何对书籍或文章的参考都可以。也许是“面向过程编程傻瓜的 XSLT 处理概念”？

使用以下 Powershell 脚本。需要使用父节点来获取数据。我创建一个父节点Root来获取结果

这是 XML 文件

这是 Powershell 脚本

using assembly System.Xml.Linq

$outputFilename = 'c:\temp\test1.xml'

$doc = [System.Xml.Linq.XDocument]::Load($inputFilename)

$root = $doc.Descendants('Root')[0]
$elements = $root.Elements();

$groups = [System.Linq.Enumerable]::GroupBy($elements,  [Func[object,object]]{ param($x) $x[0].Name.LocalName})


$distinct = [Linq.Enumerable]::Select($groups, [Func[object,object]] { param($x) $x[0] })
$orderNodes = [Linq.Enumerable]::OrderBy($distinct, [Func[object,object]] { param($x) $x[0].Name.LocalName })

$root.RemoveNodes()
foreach($node in $orderNodes)
{
   $root.Add($node)
}
