XSLT 1.0 按保留日期分组

Question

我有以下 XML 数据：

<?xml version="1.0" encoding="UTF-8" ?>
<?xml-stylesheet type="text/xsl" href="serverReserve_1.xsl" ?>

  <reservation xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="localSchema.xsd">

      <room unit="2" type="Hillview Deluxe">
        <bedType>2 Single Bed</bedType>
      </room>
    </delete>

    <roomList>

    </roomList>

    <bedList>
      <beds code="B1">Single Bed</beds>
      <beds code="B2">2 Single Beds</beds>
      <beds code="B3">King Bed</beds>
      <beds code="B4">2 King Beds</beds>
      <beds code="B5">Queen Bed</beds>
      <beds code="B6">2 Queen Beds</beds>
      <beds code="B7">3 Queen Beds</beds>
    </bedList>
  </reservation>

在 XSLT 1.0 中，我想按 reserveDate 分组并计算 reserveDate 的计数。所以在上面的数据中，我需要一个 table 来显示 reserveDate 和该日期的预订总数。

如何在 XSLT 1.0 中执行此操作？当我尝试使用这种方法时，它给了我一个错误 "Parsing an XSLT stylesheet failed."

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

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

    <head>
      <title>reserve.xsl</title>
    </head>

    <body>
      <xsl:key name="groups" match="/reservation/new" use="reserveDate" />

      <xsl:template match="/reservation">
        <xsl:apply-templates select="new[generate-id() = generate-id(key('groups', reserveDate)[1])]" />
      </xsl:template>
      <xsl:template match="new">
        <h1>
                        <xsl:value-of select="reserveDate"/>
                    </h1>
        <table id="{reserveDate}">
          <tr class="heading">
            <th scope="col">Member Id</th>
            <th scope="col">First Name</th>
            <th scope="col">Last Name</th>
          </tr>
          <xsl:for-each select="key('groups', reserveDate)">
            <tr>
              <td>
                <xsl:value-of select="name" />
              </td>
              <td>
                <xsl:value-of select="reserveTime" />
              </td>
              <td>
                <xsl:value-of select="contact" />
              </td>
            </tr>
          </xsl:for-each>
        </table>
      </xsl:template>
    </body>

    </html>
  </xsl:template>

</xsl:stylesheet>

Answer 1

您可以按如下方式修改 XSLT - 将匹配 reservation 的模板移到匹配根级别的模板之外：

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">    
<xsl:output method="html" omit-xml-declaration="yes" encoding="UTF-8" indent="yes" />
  <xsl:key name="groups" match="/reservation/new" use="reserveDate" />
  <xsl:template match="/">
    <hmtl>
      <head>
        <title>reserve.xsl</title>
      </head>
      <body>
        <xsl:apply-templates/>
      </body>
    </hmtl>
    </xsl:template>
    <xsl:template match="/reservation">
    ....
    </xsl:template>
</xsl:stylesheet>

在模板匹配根中，apply templates会调用模板匹配reservation:

<body>
  <xsl:apply-templates/>
</body>
