使用XSLT1.0对多个属性进行分组

Question

输入XML:

<?xml version="1.0" encoding="ISO-8859-1"?>
<document>
  <section name="foo" p="Hello from section foo" q="f" w="fo1"/>
  <section name="foo" p="Hello from section foo1" q="f1" w="fo1"/>
  <section name="bar" p="Hello from section bar" q="b" w="ba1"/>
  <section name="bar" p="Hello from section bar1" q="b1" w="ba1"/>
</document>

预期输出XML:

<document>
  <section name="foo" w= "fo1">
      <contain p="Hello from section foo" q="f" />
      <contain p="Hello from section foo1" q="f1" />
  </section>
  <section name="bar" w= "ba1">
      <contain p="Hello from section bar" q="b" />
      <contain p="Hello from section bar1" q="b1" />
  </section>
</document>

我的应用程序只能使用XSLT1.0，所以我不能使用xsl:for-each-group。

Answer 1

使用：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:key name="k" match="section" use="@name"/>
  <xsl:output method="xml" indent="yes"/>
  <xsl:template match="/document">
    <xsl:copy>
      <xsl:apply-templates select="section[generate-id() = generate-id(key('k', @name))]"/>
    </xsl:copy>
  </xsl:template>
  <xsl:template match="section">
    <xsl:copy>
      <xsl:copy-of select="@name | @w"/>
      <xsl:for-each select="key('k', @name)">
        <contain p="{@p}" q="{@q}"/>
      </xsl:for-each>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>
