我编写了一个 xsl，用于将我的 xml 文件的元素显示为编号列表。但我的 IE 浏览器并非每次都显示该列表。我想知道我的代码有什么问题。
这是我的 xsl 文件：
<?xml version = "1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/xsl/Transform">
<xsl:template match="/">
<html>
<body>
<ul>
<xsl:for-each select="Recipe/Ingredients/Ingredient">
<li><xsl:value-of select="name"/></li>
</xsl:for-each>
</ul>
<ol>
<xsl:for-each select="Recipe/Steps/Step">
<li><xsl:value-of select="Action"/></li>
</xsl:for-each>
</ol>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
这是我的xml文件：
<?xml version = "1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="recipe.xsl"?>
