【中文标题】如何在 XSLT 表中显示正确的内容【英文标题】：How can I display the correct content in an XSLT table 【发布时间】：2021-12-14 13:00:28 【问题描述】：我正在尝试根据日期将 XML 中的天气详细信息显示到表格中。例如。 6 月 12 日星期六是 23-28 度等。但是，我无法将详细信息插入正确的列。我曾尝试使用 xsl:if 和 xsl:when 但无济于事。我不确定使用哪个函数将其指向正确的日期。
Sample output on how it should look like

您的 XSL 嵌套了tr 标签
这个问题（或者更确切地说是作业）之前提出过：***.com/q/67651265/3016153 当时不是很清楚，现在仍然不是。但是您可能会在这些 cmets 中找到一些指针。
【参考方案1】：
要将天气信息放置在正确的单元格中，您需要在一行中添加前面和后面的单元格。
为此，您可以在 XSLT 的第一个版本中创建一个包含星期几的变量，并计算前后兄弟姐妹的数量。我在下面添加了更改 XSLT 代码。请让我知道它是否适合您。
<xsl:stylesheet version = "1.0"

【讨论】：
我认为这不会产生他们想要的结果，但我不确定他们是否知道自己想要什么。在任何情况下，您的样式表都会显示version = "1.0"，但它会在 XSLT 1.0 处理器上出错。
没有成功，但感谢您的宝贵时间！【参考方案2】：
使用给定的 XML 示例并像这样修改 XSL 文件：

I am sure that this can be done in a considerably more refined manner
but it is so long since I last used XSL I have forgotten much of what
I once knew.
You can sort of emulate an array and iterate through it so an array of
day names might work with a for-each loop...?

我知道它很粗糙 - 我根本不记得在 XSL 中做事的很多方式和方法，因为我已经很久没有使用它了。

非常感谢！坚持了这么久！非常感谢！ 不客气，但我有 99% 的把握肯定有比这更清洁的方法......如果我弄清楚了，我会更新上面的以上是关于如何在 XSLT 表中显示正确的内容的主要内容，如果未能解决你的问题，请参考以下文章
