XSL 基于属性值复制节点(如搜索)

Question

我已经附加了XML文件，我只想复制属性值是什么的节点，在我的情况下AHC_。在每个节点中，任何属性的值都以"AHC_"开头，复制该节点并忽略其他节点。

我正在尝试遵循 XSL，条件正常工作但不复制节点。你能看看并提出建议吗？

 <?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output encoding="UTF-8" indent="yes" method="xml"/>
    <xsl:strip-space elements="*"/>
    <xsl:template match="Schedules">
        <xsl:if test="Schedule[@ServiceName='MESAVisToolkit_RetentionProcessor']">
            <xsl:apply-templates select="@*|node()"/>
        </xsl:if>
    </xsl:template>
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

示例 XML：

Answer 1

条件有效，但未复制节点。

那不是真的。无条件复制所有Schedule节点。那是因为你的条件没有意义。这毫无意义，因为它与你说你想要的东西无关：

在每个节点中，任何属性都有以"AHC_"开头的值，复制该 节点

更重要的是，它毫无意义，因为它是从父Schedules元素的上下文中评估的，而不是从单个Schedule节点进行评估的。因此，如果任何Schedule子项满足条件，您将应用模板（即复制）所有这些模板。

要有选择地仅复制满足某些条件Schedule元素，应将样式表的结构构建为：

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/Schedules">
    <xsl:copy>
        <xsl:copy-of select="Schedule[--your condition goes here---]"/>
    </xsl:copy>
</xsl:template>
</xsl:stylesheet>
