这是我的XSLT代码：

<?xml version="1.0"  encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml"  version="1.0" omit-xml-declaration="yes" indent="yes" media- type="text/html"/> 

<xsl:param name="id">1</xsl:param>

<xsl:template match="/">
<html>
<head>
    <title></title>     
</head>

<body>

<div id="main">
    <br/>
    <h2>Commonwealth Games 2014 Event Information</h2>
    <hr/>
    <xsl:apply-templates select="/games/sport[@id=$id]"/>
</div>

</body>
</html>

</xsl:template>

<xsl:template match="sport">

<div id="sport">
    <b>Event: </b><xsl:value-of select="event"/>
    <br/>
    <br/>
    <b>Discipline: </b><xsl:value-of select="discipline"/>
    <br/>
    <br/>
    <b>From: </b><xsl:value-of select="fromdate"/>
    <br/>

    <b>To: </b><xsl:value-of select="todate"/>
    <br/>
    <br/>
    <b>Venue: </b><xsl:value-of select="place"/>
    <br/>
</div>

</xsl:template>

</xsl:stylesheet>

我有一个事件列表，当点击一个事件时，它会显示一个页面，其中包含来自我的XML运动部分的详细信息。

在这个页面上我还想要一个场地图像，所以我想做这样的事情：

如果在体育部分，该地方说“汉普顿公园”，那么我希望它与场地部分中的名称相匹配，并从图像标签中显示图像。

我使用ColdFusion生成HTML页面。

任何帮助都会非常感激。

Answer 1

如果你可以硬编码图像，这就是你如何引入条件。你要找的是xsl:choose元素，我敢说。

这是一个简单的示例，说明如何根据现有样式表中变量$id的值将图像输出到HTML。

<xsl:choose>
  <xsl:when test="$id = '01'">
     <xsl:element name="img">
        <xsl:attribute name="src">
           <xsl:value-of select="venue[@id='01']/image"/>
        </xsl:attribute>
        <xsl:attribute name="alt">
           <xsl:value-of select="venue[@id='01']/alt"/>
        </xsl:attribute>
     </xsl:element>
  </xsl:when>
  <xsl:otherwise>
     <xsl:element name="img">
        <xsl:attribute name="src">
           <xsl:value-of select="venue[@id='04']/image"/>
        </xsl:attribute>
        <xsl:attribute name="alt">
           <xsl:value-of select="venue[@id='04']/alt"/>
        </xsl:attribute>
     </xsl:element>
  </xsl:otherwise>
</xsl:choose>
