根据输入 xml 中的复杂元素将 XML 转换为 HTML

【问题标题】：Converting XML to HTML based on complex elements in the input xml根据输入 xml 中的复杂元素将 XML 转换为 HTML
【发布时间】：2016-01-03 16:17:38
【问题描述】：

我是 XSLT 的新手，我正在尝试将以下 xml 中的数据解析为 html，其中每个 root/Quote/Quotes 是一个 Vehicle，Vehicle 的值是根据相应报价中的 QuoteId 确定的，我需要根据 QuoteID 并排显示 Quote-1 和 Quote-2 和 QuoteID 在 1st <Sequence> 和 2nd <Sequence> 下的相应值，我需要显示所有根/Quotes/Quote 中的所有不同元素它的值，或者如果任何元素或元素的值不存在 - 我需要显示“未找到”

有可能第一个 <Sequence> 可以有 root/Quotes/Quote's 和 <SequenceID> 的 1、2、3 和第二个 <Sequence> 可以有 <SequenceID> 的 1 和 3，在这种情况下我需要将 Quote-2 的所有标签值显示为“未找到”

输入 XML

【问题讨论】：

  • 您的问题不清楚。您的输入中没有 。而且很难理解输入到输出的映射——尤其是。当某些值不唯一时。
  • 对不起，我的意思是 QuoteID，如果值存在，我需要所有元素的名称都存在于所有具有值的车辆中，如果不存在，值应该是“未找到”
  • 每个 代表一个事务（命名为 值），每个 Quotes/Quote 代表该事务下的一个 Quote，我的要求是显示 具有的值相同的 在不同的 在 HTML 中并排。提前致谢！

【解决方案1】：

您正在将输入中的行转换为输出中的列，并且您正在寻找可能未包含在每个 &lt;Quote&gt; 中的元素。

要管理它，您需要一个所有可能元素名称的列表和&lt;Quotes&gt; 的最大数量。

然后您可以通过position() 循环遍历Quotes 的列表，并从$elements 列表中查找所有元素。

【讨论】：

  • 感谢您的回复，我应该使用 xslt 2.0，我可以使用 distinct-values() 和 count() 获取完整节点列表和计数，我目前无法显示值，有人可以帮助我提供完整的解决方案。
  • 您仍然可以使用相同的两个模板（match="/" 和 name="outputVehicle"）。但是，xslt 2.0 也支持分组，这可能会使其更简单。
  • 而且这个解决方案仍然适用于 xslt-2.0 转换器。
  • 感谢 Rolf 的回复，我已经用 2 个 xslt 制定了解决方案。我将根据需要将其调整为 XSLT 2.0。再次感谢！！
