从xsl中排除结果

Question

这段代码来自我发送的一个附加的xsl，当我告诉我的客户端，配置文件错误地排除了标题中带有“北爱尔兰”的内容。现在，他把一切都带回来了，但是我需要排除一些结果--下面的一个例子。

我想从结果中筛选出的对象的标识信息是nisr in affectingURI，例如键-33793274a92a1f194b3ebcfccfc08927。

我怎样才能摆脱这些“nisr”的结果？

<xsl:template match="atom:feed" mode="results">
    <xsl:apply-templates select="atom:entry/ukm:Effect"/>
</xsl:template>
<xsl:template match="ukm:Effect">
    <xsl:choose>
        <xsl:when test="@Type= 'Commencement Order' and @AffectedProvisions='specified amended provision(s)'"/>
        <xsl:when test="contains(ukm:AffectingTitle[1], 'Northern Ireland')"/>
        <xsl:when test="contains(ukm:AffectingTitle[1], 'Northern-Ireland')"/>
        <xsl:when test="contains(ukm:AffectedTitle[1], 'Northern Ireland')"/>
        <xsl:when test="contains(ukm:AffectedTitle[1], 'Northern-Ireland')"/>
        <xsl:when test="@Type= 'coming into force'"/>
        <xsl:otherwise>
            <tr xsl:exclude-result-prefixes="atom xs xhtml tso db sls ukm">
                <xsl:apply-templates select="." mode="resultsAffectedYearNumber"/>
                <xsl:apply-templates select="." mode="resultsAffectedTitle"/>
                <xsl:apply-templates select="." mode="resultsChangedProvision"/>
                <xsl:apply-templates select="." mode="resultsAffectingTitle"/>
                <xsl:apply-templates select="." mode="resultsInForceDates"/>
                <xsl:apply-templates select="." mode="resultsEffectId"/>
            </tr>
        </xsl:otherwise>
    </xsl:choose>

这是消息来源。

-我希望我的结果中没有"key-33793274a92a1f194b3ebcfccfc08927“，因为它包含NISR。

-If您可以帮助我排除NISR，我将采用相同的逻辑，并将其应用于“key-e789d8a9e46169ba1f49655051c66d1”，因为affectingURI中的NIA也是我需要省略的六个句柄之一。

-The UK pga (英国公共和一般行为，对于那些想知道自己在看什么的人来说！)结果("key-fce2f92caeab329b0d33dfb1adca9bdf")将包括在内。在替换配置之前，我的出发点是缺少这个，因为它的标题中有北爱尔兰，而且在一些我无法识别的地方，它被错误地排除在外。提交人只应排除NIA、NISR、NISI。

Answer 1

我不确定我是否完全理解这个问题，但是当你说“我想过滤掉affectingURI中的结果是nisr”时，解决这个问题的一种方法就是使用模板匹配来排除问题。

当前有一个匹配ukm:Effect的模板，它与所有这样的命名元素匹配。

<xsl:template match="ukm:Effect">

如果您有一个规则，ukm:Effect元素将被排除在nisr位于affectingURI中的位置，那么您应该添加另一个模板，如下所示

<xsl:template match="ukm:Effect[contains(@AffectingURI, '/nisr/')]" />

因为该模板在元素名称之后有一个条件，因此它将比其他模板具有更高的优先级，从而导致该ukm:Effect元素被排除在外。

所以，与其使用xsl:choose / xsl:when来排除元素.

<xsl:when test="contains(ukm:AffectingTitle[1], 'Northern Ireland')"/>

您可以将其重写为模板匹配以排除它。

<xsl:template match="ukm:Effect[contains(ukm:AffectingTitle[1], 'Northern Ireland')]"/>

但是要小心，匹配ukm:Effect[contains(ukm:AffectingTitle[1], 'Northern Ireland')]的模板与匹配ukm:Effect[contains(@AffectingURI, '/nisr')]的模板具有相同的优先级(因为两者都有条件)。如果两个模板可以以相同的优先级匹配相同的元素，则认为这是一个错误。在本例中，您可能需要在第二个模板上添加一个priority属性。

<xsl:template match="ukm:Effect[contains(@AffectingURI, '/nisr')]" priority="2" />

或者，您可以使用一个大的条件检查模板。

<xsl:template match="ukm:Effect[contains(@AffectingURI, '/nisr/') or contains(ukm:AffectingTitle[1], 'Northern Ireland')]"/>
