使用xslt根据子值获取xml节点
我有一个如下所示的XML使用xslt根据子值获取xml节点,xml,xslt,Xml,Xslt,我有一个如下所示的XML <BackgroundReports> <BackgroundReportPackage> <Screenings> <Screening type="PEMP"> <ScreeningStatus> <OrderStatus>Completed</OrderStatus&g
<BackgroundReports>
<BackgroundReportPackage>
<Screenings>
<Screening type="PEMP">
<ScreeningStatus>
<OrderStatus>Completed</OrderStatus>
<ResultStatus>Review</ResultStatus>
</ScreeningStatus>
</Screening>
<Screening type="PEMP">
<ScreeningStatus>
<OrderStatus>Completed</OrderStatus>
<ResultStatus>Review</ResultStatus>
</ScreeningStatus>
</Screening>
<Screening type="FEMP">
<ScreeningStatus>
<OrderStatus>Completed</OrderStatus>
<ResultStatus>Fail</ResultStatus>
</ScreeningStatus>
</Screening>
<Screening type="PEMP">
<ScreeningStatus>
<OrderStatus>Completed</OrderStatus>
<ResultStatus>Pass</ResultStatus>
</ScreeningStatus>
</Screening>
<Screening type="TEST">
<ScreeningStatus>
<OrderStatus>Completed</OrderStatus>
<ResultStatus>Review</ResultStatus>
</ScreeningStatus>
</Screening>
</Screenings>
</BackgroundReportPackage>
</BackgroundReports>
它从原始XML中删除了3个FEMP/PEMP筛选元素
第二个优先事项是审查,如果没有失败-审查,但如果有多个/所有审查要素,则只获得一个要素
第三,如果没有审查和失败,则通过,但如果多个/所有筛选元素通过,则仅获得一个元素
此外,还应列出除PEMP和FEMP之外的其他筛选元素
这是我迄今为止工作的xslt

</xsl:for-each>

因为您使用的是XSLT2.0,所以可以声明排序顺序并拆分值
<xsl:param name="sortOrder" select="'Fail,Review,Pass'" />
<xsl:variable name="valSequence" select="tokenize($sortOrder, ',')"/>
对于其余节点,按原样应用它们
<xsl:apply-templates select="Screening[not(@type = 'FEMP' or @type = 'PEMP')]" />
完整的XSLT如下所示
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" />
<xsl:strip-space elements="*" />
<xsl:param name="sortOrder" select="'Fail,Review,Pass'" />
<xsl:variable name="valSequence" select="tokenize($sortOrder, ',')"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="Screenings">
<xsl:copy>
<xsl:for-each select="Screening[@type = 'FEMP' or @type = 'PEMP']">
<xsl:sort select="index-of($valSequence, ScreeningStatus/ResultStatus)" />
<!-- Get 1st element after sorting -->
<xsl:if test="position() = 1">
<xsl:copy>
<xsl:apply-templates select="@* | node()" />
</xsl:copy>
</xsl:if>
</xsl:for-each>
<xsl:apply-templates select="Screening[not(@type = 'FEMP' or @type = 'PEMP')]" />
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

您能分享到目前为止编写的XSLT代码吗?如果您还可以根据上述优先级添加所需的输出,这将非常有用。您想让所有的测试都先失败,然后复查,并在输出XML的末尾通过测试吗。@AniketVUpdated@AniketV是的,首先失败,然后检查下一步并在输出xml结束时通过。我只需要一个筛选元素用于PEMP和FEMPDo。你的意思是你想从每个结果状态中筛选一个?不,排序后我只需要一个元素,它可以是FEMP或PEMP,具体取决于种类。我从您的xslt中得到了结果。只需拉动排序结果的第一个筛选元素,在这种情况下,它将拉动FEMP或PEMP的第一个筛选。Sort无法获取appliedI需要排序然后获取第一个元素
