所有节点的XSLT MUENCHIAN方法

我正在尝试获取元素祖先,自我和后代的属性值。然后我想显示唯一值。

这就是我想要的。

<xsl:key name="remove" match="value" use="sortedvalues" />

<xsl:for-each select="ancestor-or-self::node()/@value[generate-id() = generate-id(key('remove',sortedvalues)[1])] | descendant-or-self::node()/@value[generate-id() = generate-id(key('remove',sortedvalues)[1])]">

            <xsl:for-each select="key('remove',sortedvalues)">
            <xsl:sort select="sortedvalues"></xsl:sort>

            </xsl:for-each>

            </xsl:for-each>

这是实际的XML

<Root>

     <something value = “asd” </something>
    <something value = “dsa” </something>
  <Product>
    <something value = "asd"></something>
    <something value = "dsa"></something>
    <something value = "asd"></something>

    <anothernode>
    <something value = "qwe"></something>
    </anothernode>

    <anothernode2>
    <something value = "ewq"></something>
    </anothernode2>

    <something value = "ewq"></something>

<Product>

  <Product>
    <something value = "asd"></something>
    <something value = "dsa"></something>
    <something value = "asd"></something>

    <anothernode>
    <something value = "qwe"></something>
    </anothernode>

    <anothernode2>
    <something value = "ewq"></something>
    </anothernode2>

    <something value = "ewq"></something>

<Product>
</Root>

我基本上想要表演

<Product>
    <values>asd <values>
    <values>dsa<values>
    <values>qwe<values>
    <values>ewq<values>
<Product>


<Product>
    <values>asd <values>
    <values>dsa<values>
    <values>qwe<values>
    <values>ewq<values>
<Product>

所以我不能使用//来展示每个产品,所以我一直在产品上使用祖先和后代

如果您想按产品获取唯一的value属性,则必须引用密钥的产品部分

 <xsl:key name="values" match="@value" use="concat(generate-id(ancestor::Product), '|', .)" />

然后,对于给定的产品,您将得到如此不同的值(其中$id是一个包含产品的generate-id()值的变量)

<xsl:for-each select=".//@value[generate-id() = generate-id(key('values', concat($id, '|', .))[1])]">

试试这个XSLT

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

  <xsl:key name="values" match="@value" use="concat(generate-id(ancestor::Product), '|', .)" />

  <xsl:template match="Product">
    <xsl:variable name="id" select="generate-id()" />
    <xsl:copy>
        <xsl:for-each select=".//@value[generate-id() = generate-id(key('values', concat($id, '|', .))[1])]">
            <values><xsl:value-of select="." /></values>
        </xsl:for-each>
    </xsl:copy>
  </xsl:template>
</xsl:stylesheet>

注意,如果您可以升级到XSLT 2.0,那么您可以使用xsl:for-each-group,如此

<xsl:for-each-group select=".//@value" group-by=".">

或者您可以使用distinct-values(),就像这样

<xsl:for-each select="distinct-values(.//@value)">
