xml - 为什么不处理 xsl:template 匹配？

Question

我有这个 XML 片段：

<?xml version="1.0"?>
<FDT xmlns="x-schema:FDTMISPScanIdentSchema.xml" xmlns:mispident="x-schema:FDTMISPIdentSchema.xml"
    xmlns:fdt="x-schema:FDTDataTypesSchema.xml">
    <ScanIdentifications fdt:busCategory="D5FABA0D-8EE1-4AD0-8D2F-9B2D052C10C4"
        resultState="final">
        <ScanIdentification>
            <IdBusProtocol mispident:busProtocol="MISP" />
            <IdBusProtocolVersion
                mispident:mispRevisionLevel="1" />
            <IdManufacturer
                mispident:manufacturerIdentificationCode="32" />
            <IdAddress mispident:address="9600N81" />
            <IdTypeID mispident:deviceTypeCode="60" />
            <IdSerialNumber mispident:serial="0" />
            <IdSoftwareRevision mispident:softwareRevision="1.0.4" />
            <IdHardwareRevision />
        </ScanIdentification>
    </ScanIdentifications>
</FDT>

我正在使用这个 XSLT 来转换 xml：

<?xml version="1.0" encoding="UTF-8"?>

我得到这个输出：

            <IdValues />
        </ScanIdentification>
    </ScanIdentifications>
</FDT>

我不明白为什么 xsl:apply-templates 匹配 mispscan:IdTag 未被处理。我希望在 IdHardwareRevision 之后有一个元素，如下所示：

<IdDeviceTag xmlns:ident="x-schema:DTMIdentSchema.xml" ident:value="" ident:protocolSpecificName="Tag"/>

是不是因为模板：

<xsl:template match="mispscan:IdTag">
    <xsl:element name="IdDeviceTag">
        <xsl:attribute name="ident:value"/>
        <xsl:attribute name="ident:protocolSpecificName">Tag</xsl:attribute>
    </xsl:element>
</xsl:template>

对源文档或类似的东西没有任何匹配测试吗？我注意到，如果我只是像这样在 mispscan:ScanIdentification 模板中生成元素

<xsl:template match="mispscan:ScanIdentification">
        <xsl:element name="ScanIdentification">
            <xsl:apply-templates select="@configuredState" />
            <xsl:apply-templates select="fdt:CommunicationError"/>
            <xsl:apply-templates select="mispscan:IdBusProtocol"/>
            <xsl:apply-templates select="mispscan:IdBusProtocolVersion"/>
            <xsl:apply-templates select="mispscan:IdAddress"/>          
            <xsl:apply-templates select="mispscan:IdManufacturer"/>
            <xsl:apply-templates select="mispscan:IdTypeID"/>
            <xsl:apply-templates select="mispscan:IdSoftwareRevision"/>
            <xsl:apply-templates select="mispscan:IdHardwareRevision"/>
            <!-- don't get why this particular template doesn't work 
            <xsl:apply-templates select="mispscan:IdTag"/>
            -->
            <xsl:element name="IdDeviceTag">
                <xsl:attribute name="ident:value"/>
                <xsl:attribute name="ident:protocolSpecificName">Tag</xsl:attribute>
            </xsl:element>
            <xsl:apply-templates select="mispscan:IdSerialNumber"/>
            <xsl:element name="IdValues">
                <xsl:apply-templates select="mispscan:DeviceCommandRevisionLevel"/>
                <xsl:apply-templates select="mispscan:DeviceFlag"/>
                <xsl:apply-templates select="mispscan:ManufacturerSpecificExtension"/>
            </xsl:element>
        </xsl:element>
</xsl:template>

它按我预期的方式工作。

我想这很好，但我想确切地知道为什么 mispscan:IdTag 模板没有得到处理。

Answer 1

一般来说，匹配特定元素的模板可能不会被评估有几个原因：

• 样式表中没有 xsl:apply-templates 会导致模板匹配发生在相关元素上。在许多以传统 XSLT 样式编写的样式表中，这归结为：匹配父元素的模板不包含任何 xsl:apply-templates 指令。

• 还有另一个具有更高优先级的模板与相关元素匹配。

• 输入中没有与模板匹配的元素。

由于您显示的输入中没有 mispscan:IdTag 元素，因此在这种情况下，原因似乎是第三个：您的 mispscan:IdTag 模板没有被评估，因为它与输入中的任何内容都不匹配。
