xml - 在 xslt 中显示简单的 xml

Question

我花了大约 6-7 个小时试图让一个基本的 xml 页面显示至少使用 xsl 可读，并且无法理解它。有那么难吗？或者我只是在苦苦挣扎。

我的 xml 代码是基本的

    <method>
      <step>1. Place the prawns in a pot and add enough water to cover them. Boil for 5 minutes, then drain, reserving the liquid and set aside.</step>
      <step>2. Heat about 2 tablespoons of oil in a saucepan. Add the onion and cook and stir until the onions are soft. Mix in the parsley, wine, tomatoes, garlic and remaining olive oil.</step>
      <step>3. Simmer, stirring occasionally, for about 30 minutes, or until the sauce is thickened.</step>
      <step>4. While the sauce is simmering, the prawns should have become cool enough to handle. First remove the legs by pinching them, and then pull off the shells, leaving the head and tail on.</step>
      <step>5. When the sauce has thickened, stir in the prawns. Bring to a simmer, and cook for about 5 minutes.</step>
      <step>6. Add the feta cheese and remove from the heat. Let stand until the cheese starts to melt. Serve warm.</step>

是否可以按顺序显示它，以便可以在 xsl 文档中的几行基本行中轻松阅读食谱？

Answer 1

您可以从使用一些通用规则快速而简单地转换为 HTML 开始，然后通过添加更多规则对其进行自定义以使其更漂亮。这是一个启动器，它根据元素和属性在文档中的深度显示它们；它并不漂亮，但它是一个起点：

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >

<xsl:template match="/">
  <html><body><xsl:apply-templates/></body></html>
</xsl:template>

<xsl:template match="*/*">
  <h1>
   <xsl:value-of select="name()"/>
   <xsl:apply-templates select="@*"/>
  </h1>  
   <table>
     <xsl:apply-templates select="*"/>
   </table>
</xsl:template>

<xsl:template match="*/*/*">
  <tr>
    <td><xsl:value-of select="name()"/></td>
    <td><xsl:apply-templates/></td>
  </tr>
</xsl:template>

<xsl:template match="*/*/*/*">
  <dt>
    <xsl:value-of select="name()"/>
    <xsl:apply-templates select="@*"/>
  </dt>
  <dd><xsl:value-of select="."/></dd>
</xsl:template>

<xsl:template match="@*">
  <xsl:value-of select="concat(' ', name(), ': ', .)"/>
</xsl:template>
</xsl:stylesheet>
