哪些元素具有最小子元素XSL

Question

这是xml文件:

<sinonime>
	<cuvant titlu="timp">
		<definitie>durata care corespunde desfasurarii unui evenimen</definitie>
		<sens>vreme</sens>
		<sens>sezon</sens>
		<sens>durata</sens>
	</cuvant>
	<cuvant titlu="harnic">
		<definitie>care munceste mult, repede si cu folos</definitie>
		<sens>muncitor</sens>
		<sens>sarguincios</sens>
	</cuvant>
	<cuvant titlu="Enervat">
		<definitie>scos din fire, in stare de iritare</definitie>
		<sens>nervos</sens>
	</cuvant>
	<cuvant titlu="parfum">
		<definitie>ceva cu miros placut, frumos</definitie>
		<sens>mireasma</sens>
		<sens>esenta</sens>
		<sens>miros</sens>
		<sens>colonie</sens>
	</cuvant>
	<cuvant titlu="Eprubeta">
		<definitie>tub de sticla inchis la capat</definitie>
		<sens>tub</sens>
	</cuvant>
	<cuvant titlu="medicament">
		<definitie>substanta utilizata pentru a vindeca, ameliora sau preveni o boala</definitie>
		<sens>elixir</sens>
		<sens>leac</sens>
		<sens>remediu</sens>
	</cuvant>
</sinonime>

我期望输出:

Enervat

Eprubeta

因为这些元素只有一个感知(子元素的最小计数'感知')

如何返回哪些元素具有最小子元素?

我试着:

<xsl:for-each select="sinonime/cuvant">
	<xsl:sort select="count(document('sinonime.xml')//cuvat/sens)"/>
	<xsl:if test="position()=last()">
	  <xsl:value-of select="@titlu"/>
	</xsl:if>
</xsl:for-each>

Answer 1

使用您的问题中的for-each循环，您将只获得具有最小sens节点计数的元素中的1个。例如，您可以使用第一个for-each来获得最小计数，然后打印所有cuvant节点的titlu属性值，如下所示:

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text"  omit-xml-declaration="yes" encoding="UTF-8" indent="yes" />
<xsl:template match="sinonime">
  <xsl:variable name="min">
    <xsl:for-each select="cuvant">
      <xsl:sort select="count(sens)" data-type="number" order="ascending"/>
      <xsl:if test="position()=1">
        <xsl:value-of select="count(sens)"/>
      </xsl:if>
    </xsl:for-each>
  </xsl:variable>
  <xsl:for-each select="cuvant[count(sens)=$min]">
   <xsl:value-of select="@titlu"/>
     <xsl:if test="position() != last()">
       <xsl:text>&#xa;</xsl:text>
      </xsl:if>
    </xsl:for-each>
  </xsl:template>
</xsl:transform>

当应用到您的输入时，将产生输出

Enervat
Eprubeta

Answer 2

可以很容易地解决这个问题，首先创建一个简单的文档，其中包含每个"cuvant"的计数和名称，如:

<counts>
   <count name="timp" n="3"/>
   <count name="harnic" n="2"/>
   ...
</counts>

从那里很容易得到最小值，选择所有@n最小的地方，并正确显示它们(这是一个完整的例子，有趣的部分是最后2个模板):

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:xs="http://www.w3.org/2001/XMLSchema"
                exclude-result-prefixes="xs"
                version="2.0">
   <xsl:variable name="doc" as="element()">
      <sinonime>
        <cuvant titlu="timp">
            <definitie>durata care corespunde desfasurarii unui evenimen</definitie>
            <sens>vreme</sens>
            <sens>sezon</sens>
            <sens>durata</sens>
        </cuvant>
        <cuvant titlu="harnic">
            <definitie>care munceste mult, repede si cu folos</definitie>
            <sens>muncitor</sens>
            <sens>sarguincios</sens>
        </cuvant>
        <cuvant titlu="Enervat">
            <definitie>scos din fire, in stare de iritare</definitie>

            </result>
         </xsl:for-each>

   <xsl:template match="cuvant">
