我必须编写以下xml标记的XSL样式表。
<?xml version = "1.0"?>
<?xml-stylesheet type = ""text/xsl" href = "cookies.xsl"?>
<product name="Grandma White's Cookies">
<servingsize>1 package</servingsize>
<calories>
<total>260 Calories</total>
<fat>100 Calories</fat>
</calories>
<fat>
<total>11 grams</total>
<saturated>2 grams</saturated>
</fat>
<cholesterol>
5 milligrams</cholesterol>
<sodium>
210 milligrams</sodium>
<carbohydrates>
<total>36 grams</tota`enter code here`l>
<fiber>2 grams</fiber>
<sugars>15 grams</sugars>
</carbohydrates>
<protein>5 grams</protein>
</product>
我的xsl标记如下。我需要以表格形式显示信息。我尝试输出下面的信息，但是没有显示。你能帮我解决一下吗？
<?xml version = "1.0"?>
<xsl:stylesheet version ="1.0"
xmlns:xsl = "http://www.w3.org/1999/XSL/Transform">
<xsl:output method = "html" doctype-system = "about:legacy-compat" />
<xsl:template match = "/">
<html xmlns = "http://www.w3.org/1999/xhtml">
<head>
<meta charset = "utf-8" />
<link rel = "stylesheet" type = "text/css" href ="style.css" />
<title>Grandma White's cookies</title>
</head>
<body>
<h1>

<h3>Serving size <xsl:value-of select="servingsize"/></h3>
<table>
<thead>
<tr>
<th>Description></th>
<th>Information</th>
</tr>

<xsl:for-each select="/calories">
<tr>
<td>Calories</td>
<td><xsl:for-each select="total"/><br></br>
<xsl:for-each select="fat"/></td>
</tr>
</xsl:for-each>

</body>
</html>
</xsl:template>
</xsl:stylesheet>

这是一个可以用作起点的样式表。请注意，产品的名称不是硬编码的，因此可以与任何产品一起使用。 OTOH，假设每种产品的营养数据采用相同的格式。
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" encoding="utf-8" indent="yes"/>
<xsl:template match="/">
<html>
<head>
<title>
<xsl:value-of select="product/@name"/>
</title>
</head>
<body>
<h1>
<xsl:value-of select="product/@name"/>
<xsl:text> Nutrition Facts</xsl:text>
</h1>
<h3>
<xsl:text>Serving size: </xsl:text>
<xsl:value-of select="product/servingsize"/>
</h3>
<table>

<xsl:value-of select="product/calories/total"/>
<br/>
<xsl:text>Fat: </xsl:text>

<!-- more rows -->

此样式表
<?xml version = "1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" doctype-system="about:legacy-compat"></xsl:output>
<xsl:variable name="smallcase" select="'abcdefghijklmnopqrstuvwxyz'" />
<xsl:variable name="uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'" />
<xsl:template match="/">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8"></meta>
<link rel="stylesheet" type="text/css" href="style.css"></link>
<title>Grandma White's cookies</title>
</head>
<body>
<h1>Grandma White's cookie nutrition facts</h1>
<h3>Serving size: <xsl:value-of select="product/servingsize"></xsl:value-of></h3>
<table>
<thead>
<tr>
<th>Description</th>
<th>Information</th>
</tr>
</thead>
<tbody>
<xsl:for-each select="/product/*[not(self::servingsize)]">
<tr>
<td>
<xsl:value-of select="translate(substring(local-name(), 1, 1), $smallcase, $uppercase)"/>
<xsl:value-of select="substring(local-name(), 2)"/>
</td>
<td>
<xsl:choose>
<xsl:when test="*">
<xsl:for-each select="*">
<xsl:choose>
<xsl:when test="position() != last()">
<xsl:value-of select="concat(local-name(), ': ', .)"/><br/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="concat(local-name(), ': ', .)"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="."/>
</xsl:otherwise>
</xsl:choose>
</td>
</tr>
</xsl:for-each>
</tbody>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
应用于输入XML时，生成：
<!DOCTYPE html
SYSTEM "about:legacy-compat">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8"></meta>
<link rel="stylesheet" type="text/css" href="style.css"></link>
<title>Grandma White's cookies</title>
</head>
<body>
<h1>Grandma White's cookie nutrition facts</h1>
<h3>Serving size: 1 package</h3>
