,但我还没弄明白

<xsl:stylesheet 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" omit-xml-declaration="yes"/>

    <xsl:key name="groupbydate" match="entry" use="updated"/>

    <xsl:template match="feed">
        <blah>
          <xsl:apply-templates
                select="entry[
                    generate-id() 
                    = generate-id(key('groupbydate', updated)[1])]" />
        </blah>
    </xsl:template>

    <xsl:template match="entry">
        <!-- GET the date -->
        <xsl:variable name="date" select="substring(updated,1,10)"/>
        <today>
            <date><xsl:value-of select="$date"/></date>
        </today>
        <xsl:for-each select="entry">
            <xsl:if test="preceding-sibling::entry[substring(updated,1,10) = $date]">
            <post>
                <xsl:copy-of select="entry"/>
            </post>
        </xsl:if>
        </xsl:for-each>
    </xsl:template>

</xsl:stylesheet>

将密钥定义为

<xsl:key name="groupbydate" match="entry" use="substring-before(updated, 'T')"/>

那么你需要使用它

<xsl:template match="feed">
    <blah>
      <xsl:apply-templates
            select="entry[
                generate-id() 
                = generate-id(key('groupbydate', substring-before(updated, 'T'))[1])]" />
    </blah>
</xsl:template>

然后,您使用

<xsl:template match="entry">
  <today>
    <date><xsl:value-of select="substring-before(updated, 'T')"/></date>
    <xsl:apply-templates select="key('groupbydate', substring-before(updated, 'T'))" mode="entry"/>
  </today>
</xsl:template>
<xsl:template match="entry" mode="entry">
  <post>
    <xsl:copy-of select="node()"/>
  </post>
</xsl:template>

每组的项目都有

<xsl:template match="entry">
  <today>
    <date><xsl:value-of select="substring-before(updated, 'T')"/></date>
    <xsl:apply-templates select="key('groupbydate', substring-before(updated, 'T'))" mode="entry"/>
  </today>
</xsl:template>
<xsl:template match="entry" mode="entry">
  <post>
    <xsl:copy-of select="node()"/>
  </post>
</xsl:template>

将密钥定义为

<xsl:key name="groupbydate" match="entry" use="substring-before(updated, 'T')"/>

那么你需要使用它

<xsl:template match="feed">
    <blah>
      <xsl:apply-templates
            select="entry[
                generate-id() 
                = generate-id(key('groupbydate', substring-before(updated, 'T'))[1])]" />
    </blah>
</xsl:template>

然后,您使用

<xsl:template match="entry">
  <today>
    <date><xsl:value-of select="substring-before(updated, 'T')"/></date>
    <xsl:apply-templates select="key('groupbydate', substring-before(updated, 'T'))" mode="entry"/>
  </today>
</xsl:template>
<xsl:template match="entry" mode="entry">
  <post>
    <xsl:copy-of select="node()"/>
  </post>
</xsl:template>

</xsl:template>
<xsl:template match="entry" mode="entry">

</xsl:template>


两者都有。非常感谢,因为它帮助我理解并解决了我的问题。非常感谢。非常感谢,因为它帮助我理解并解决了我的问题。非常感谢。
