XSL将XML文件转换为3个表

标签： xml xslt

我有一个关于3个不同城市的天气数据的XML文件，现在我想使用XSl根据我的xml中的位置（卡尔加里，夏洛特敦和渥太华）将其转换为3个表。我现在的xls只是将xml转换成一个表，任何人都可以给我一个关于如何通过xml属性将xml文件转换为不同表的提示吗？ 这是我的xml 

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

假设位置名称 - 卡尔加里，夏洛特敦和渥太华 - 提前知道并且始终存在，您可以这样做：

XSLT 1.0 

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

<xsl:variable name="thead">
    <tr>
        <th>Data</th>
        <th>Maximum Temperature(°C)</th>
        <th>Minimum Temperature(°C)</th>
        <th>Total Rain(mm)</th>
        <th>Total Snow(cm)</th>
    </tr>
</xsl:variable>

<xsl:template match="/weatherdata">
    <html>
        <head>
            <title>weather data</title>
        </head>
        <body>
            <h1>Calgary-Temperature Summary(2015)</h1>
            <table border="1">
                <xsl:copy-of select="$thead"/>
                <xsl:apply-templates select="stationdata[@location='Calgary']"/>
            </table>
            <h1>Charlottetown-Temperature Summary(2015)</h1>
            <table border="1">
                <xsl:copy-of select="$thead"/>
                <xsl:apply-templates select="stationdata[@location='Charlottetown']"/>
            </table>
            <h1>Ottawa-Temperature Summary(2015)</h1>
            <table border="1">
                <xsl:copy-of select="$thead"/>
                <xsl:apply-templates select="stationdata[@location='Ottawa']"/>
            </table>
        </body>
    </html>
</xsl:template>

<xsl:template match="stationdata">
    <tr>
        <td><xsl:value-of select="@weatherdate"/></td>
        <td><xsl:value-of select="maxtemp"/></td>
        <td><xsl:value-of select="mintemp"/></td>
        <td><xsl:value-of select="totalrain"/></td>
        <td><xsl:value-of select="totalsnow"/></td>
    </tr>
</xsl:template>

</xsl:stylesheet>

答案 1 :(得分：1)

这是一个分组问题。由于您使用的是XSLT 1.0，因此可以使用Muenchian Grouping。

您可以根据xsl:key属性创建location。

然后循环遍历每个键的第一个匹配并输出位置。

然后将模板应用于与该键匹配的所有匹配项。

评论中提到的XSLT 2.0示例。如您所见，这个基本示例没有太大区别。我们只使用xsl:for-each-group而不是密钥。

XSLT 2.0 

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="/weatherdata">

      <head>
        <title>weather data</title>
      </head>
      <body>
        <xsl:for-each-group select="stationdata" group-by="@location">
          <h1><xsl:value-of select="current-grouping-key()"/>-Temperature Summary (<xsl:value-of select="substring-before(@weatherdate,'-')"/>)</h1>
          <table border="1">
            <tr>
              <th>Data</th>
              <th>Maximum Temperature(°C)</th>
              <th>Minimum Temperature(°C)</th>
              <th>Total Rain(mm)</th>
              <th>Total Snow(cm)</th>
            </tr>
            <xsl:apply-templates select="current-group()"/>
          </table>
        </xsl:for-each-group>
      </body>
    </html>
