Question

我有点卡住了。我想让我的XSLT文件在以下情况下设置表格中行的背景颜色：

origin = USA到＃4286f4

origin = UK to＃ed3d3d

origin = CS到＃3dd2ed

origin = NOR到＃000c7a

我几乎尝试了一切，但我无法让它发挥作用......有人可以帮我一点吗？

这是我的XML：

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="XSLTproject.xsl"?>

和XSLT：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">
  <html>
  <body>
    <h2>oldies!</h2>
    <table border="1">
    <tr bgcolor="#9acd32">
      <th style="text-align:center">Name</th>
      <th style="text-align:center">Country</th>
      <th style="text-align:center">Year</th>
      <th style="text-align:center">Usage</th>
      <th style="text-align:center">Picture</th>
    </tr>
    <xsl:for-each select="computers/computer">
    <tr>
      <td><xsl:value-of select="name"/></td>
      <td><xsl:value-of select="country"/></td>
      <td><xsl:value-of select="year"/></td>
      <td><xsl:value-of select="usage"/></td>
      <td><img width="400" height="400" src="{picture}"/></td>
    </tr>
    </xsl:for-each>
  </table>
  </body>
  </html>
</xsl:template>
</xsl:stylesheet>

Answer 1

您可以使用xsl:choose元素。它可以在多个备选项中选择一个值，具体取决于test属性。在您的示例中，测试只是可以将country元素的内容与字符串进行比较，以确定所需的颜色：

<xsl:for-each select="computers/computer">
  <tr>
    <xsl:attribute name="bgcolor">
      <xsl:choose>
        <xsl:when test="country = 'USA'">#4286f4</xsl:when>
        <xsl:when test="country = 'UK'">#ed3d3d</xsl:when>
        <xsl:when test="country = 'Czechoslovakia'">#3dd2ed</xsl:when>
        <xsl:when test="country = 'Norway'">#000c7a</xsl:when>
        <xsl:otherwise>#ffffff</xsl:otherwise>
      </xsl:choose>
    </xsl:attribute>
    <td><xsl:value-of select="name"/></td>
    <td><xsl:value-of select="country"/></td>
    <td><xsl:value-of select="year"/></td>
    <td><xsl:value-of select="usage"/></td>
    <td><img width="400" height="400" src="{picture}"/></td>
  </tr>
</xsl:for-each>

Answer 2

一种可能的解决方案是创建第三个XML文件，其中包含所需的转换（trans.xml），其中包含从国家/地区代码到HTML颜色代码的必要转换：

<?xml version="1.0" encoding="UTF-8"?>
<bgcolor>
  <color origin="USA">#4286f4</color>
  <color origin="UK">#ed3d3d</color>
  <color origin="CS">#3dd2ed</color>
  <color origin="NOR">#000c7a</color>
</bgcolor>

使用名称为trans.xml的第三个XML文件，使用如下的XSLT文件

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:variable name="colors" select="document('trans.xml')/bgcolor" />

    <xsl:template match="/">
        <html>
            <body>
                <h2>oldies!</h2>
                <table border="1">
                    <tr bgcolor="">
                        <th style="text-align:center">Name</th>
                        <th style="text-align:center">Country</th>
                        <th style="text-align:center">Year</th>
                        <th style="text-align:center">Usage</th>
                        <th style="text-align:center">Picture</th>
                    </tr>
                    <xsl:for-each select="computers/computer">
                        <xsl:variable name="curColor" select="@origin" />
                        <tr bgcolor="{$colors/color[@origin=$curColor]/text()}">
                            <td>
                              <xsl:value-of select="name"/></td>
                            <td>
                              <xsl:value-of select="country"/></td>
                            <td>
                              <xsl:value-of select="year"/></td>
                            <td>
                              <xsl:value-of select="usage"/></td>
                            <td>
                              <img width="400" height="400" src="{picture}"/>
