Question

我有一些难以处理的标记，它没有标准化的ID。让我举例说明标记的外观：

<listing>
    <foo fooid="81">Foo</foo>
    <bar barid="88">Bar</bar>
</listing>
<listing>
    <foo fooid="82">Foo</foo>
    <bar barid="81">Bar</bar>
</listing>
<listing>
    <foo fooid="83">Foo</foo>
    <bar barid="81">Bar</bar>
</listing>

在这种情况下，我需要能够填入<xsl:variable />的ID为81，因为无论其标记如何，id都表示最多次。使用XSLT有一个简单的方法吗？理想情况下，当它说完了，我会有类似的东西：

<xsl:variable name="an_id">其中an_id等于81

已知要点如下：

标签总是被称为foo或bar。
属性总是被称为fooid或barid
我想要在变量中捕获的数字将在两个标记中的任意一个中列出至少一次
我想要捕捉的号码肯定会在每个列表中至少出现一次。
不相关的数字可能会或不会出现多次。

我正在使用XSLT 1.0。变量名称不是动态的。它是静态的，只要它导出的值是上面的81就可以称为whatever。

**更新**

我上面粘贴的XML是样本，虽然我认为Mads的答案是正确的，但它没有解析，所以我用我正在处理的真实XML进行更新。您可以在我的设计示例中看到<foo>和<bar>正在尝试处理<hometeam>和<awayteam>标记的等效内容，这些标记是关注的重点。< / p>

基本上我正在努力获得主队的身份证。由于它没有在列表之前进行规范化，因此我必须选择在每个列表中列出的团队（因此显示最多）。在这种情况下，费城的ID为“081”，但是一旦在XSLT处理器上运行number()，它就应该是81。

这是我到目前为止基于Mads回答的样式表：

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

  <xsl:key name="id" match="@awayteamid | @hometeamid" use="."/>

  <xsl:template match="/message">
    <xsl:variable name="heading"><xsl:value-of select="heading"/></xsl:variable>
    <xsl:variable name="title"><xsl:value-of select="title"/></xsl:variable>
    <xsl:variable name="team_id">
      <xsl:for-each select="*/listing/*/@*">
         <xsl:sort select="count(key('id', .))" order="descending" data-type="number" />
         <xsl:if test="position()=1">
             <xsl:value-of select="."/>
         </xsl:if>
     </xsl:for-each>
   </xsl:variable>

    {
     "team_id": <xsl:value-of select="number($team_id)" /> 
    }
  </xsl:template>
</xsl:stylesheet>

最后我正在使用它的错误（假设它是因为$team_id没有正确设置）

#<JSON::ParserError: 203: unexpected token at 'NaN 
    }
  '>

Answer 1

您可以定义与其中任何一个属性匹配的键：

<xsl:key name="id" match="@fooid | @barid" use="."/>

然后创建an_id变量，其值是属性值排序列表中的第一项，使用与属性值匹配的项中的项目数。

<xsl:variable name="an_id">
   <xsl:for-each select="*/listing/*/@*">
       <xsl:sort select="count(key('id', .))" order="descending" data-type="number"/>
       <xsl:if test="position()=1">
           <xsl:value-of select="."/>
       </xsl:if>
   </xsl:for-each>
</xsl:variable>

使用您的XML和XSLT更新了答案（您几乎已经拥有，只需要调整for-each中的XPath以考虑上下文节点是什么以及在表达式得到评估时“站立”的位置）：< / p>

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

    <xsl:key name="id" match="@awayteamid | @hometeamid" use="."/>

    <xsl:template match="/message">
        <xsl:variable name="heading"><xsl:value-of select="heading"/></xsl:variable>
        <xsl:variable name="title"><xsl:value-of select="title"/></xsl:variable>
        <xsl:variable name="team_id">
            <xsl:for-each select="listing/*/@*">
                <xsl:sort select="count(key('id', .))" order="descending" data-type="number" />
                <xsl:if test="position()=1">
                    <xsl:value-of select="."/>
                </xsl:if>
            </xsl:for-each>
        </xsl:variable>

        {
        "team_id": <xsl:value-of select="number($team_id)" /> 
        }
    </xsl:template>
</xsl:stylesheet>

Answer 2

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

<xsl:key name="kFoobars" match="foo/@fooid | bar/@fooid |
                                foo/@barid | bar/@barid" use="." />

<xsl:template match="/*">
  <xsl:variable name="foobar-els" select="*/foo | */bar" />
  <xsl:variable name="foobar-atr" select="$foobar-els/@fooid | $foobar-els/@barid" />
  <xsl:for-each select="$foobar-atr[ generate-id() =
                                     generate-id( key('kFoobars',.)[1])]">
    <xsl:sort select="count(key('kFoobars',.))" data-type="number" order="descending" />
    <xsl:if test="position()=1">
      <t most-populous-id-value="{.}" />
    </xsl:if>  
  </xsl:for-each>  
</xsl:template>

</xsl:stylesheet>

XSLT确定哪个属性重复最多
