我是 xslt 的新手，正在尝试使用 xslt 从 xml 创建 html。

我不知道为什么，但我的 xslt 在只有一个元素时有效，但在多个时无效。

我尝试了各种方法，但正如我所说的那样，我是新手，不知道该怎么做。

这是我的xml

我的 xslt 是

<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Edited by XMLSpy® -->
<html xsl:version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://www.w3.org/1999/xhtml">

<xsl:for-each select="DestinationResults">
<xsl:for-each select="Destination">
<xsl:for-each select="HotelAvailabilityListResults">
<xsl:for-each select="Hotel">





      <div style="background-color:teal;color:white;padding:4px">
        <span style="font-weight:bold"><xsl:value-of select="name"/></span>
        - <xsl:value-of select="city"/>
      </div>
      <div style="margin-left:20px;margin-bottom:1em;font-size:10pt">
        <p><xsl:value-of select="shortDescription"/>.
        <span style="font-style:italic">
          <xsl:value-of select="address1"/> 
        </span>.</p>
      </div>
    </xsl:for-each>
 </xsl:for-each>
 </xsl:for-each>
</xsl:for-each>

  </body>
</html>

此 xslt 适用于上述 xml，但是当 xml 中有多个酒店订单（如下所示）时，xslt 不会产生任何结果。

编写嵌套的 for-each 指令是 XSLT 初学者最常犯的错误。这不是这样做的方法：从使用模板规则开始，并且仅在您对语言足够了解以了解它有用的情况时才使用 for-each。

当然，在这种情况下，您还可以通过使用路径来简化代码：

<xsl:for-each select="DestinationResults/Destination/HotelAvailabilityListResults/Hotel">

像这样的调试问题需要对 XML 树结构有清晰的理解，如果正确缩进 XML，获得这种理解会容易得多。我不确定您所说的“多个酒店订单”是什么意思 - 我在您的第二个示例中只看到一个订单。也许问题是您的第二个示例没有您的样式表假设的 DestinationResults/Destination/HotelAvailabilityListResults 包装器元素；无论如何，如果他们在那里，那么您还没有向他们展示。将代码放在带有 match="Hotel" 的模板规则中可以避免这种对包装器中存在的内容的依赖。
