XSLT 用同级文本内容匹配的另一个文件“替换”值

Question

我正在寻求有关使用 XSLT 1.0 替换两个 XML 文件中的值的帮助。我相信我已经接近了，但需要一些指导来微调我目前所拥有的。

首先是问题：这两个 XML 文件本质上是一样的。我正在用第二个文件及其所有子文件中的节点替换第一个文件中的两个节点，但我当前的实现是创建重复项。我确定这是因为我的 XPath 正在返回我给它的所有节点，但我不知道如何调整谓词，以便它仅在匹配兄弟节点时才替换 - 特别是 .

文件 1 - Networks.xml

<?xml version="1.0" encoding="utf-8"?>
<Network_Records xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Networks.xsd">
  <NetworkSwitch>
    <ChannelID>A</ChannelID>
    <SwitchName>OPS1</SwitchName>
    <RackNumber>T5553</RackNumber>
    <Elevation>A14</Elevation>
    <RoomLocation>Phoenix</RoomLocation> 
   <NetworkSwitchConfigModule>switch_1_phx.txt</NetworkSwitchConfigModule>
    <Override>false</Override>
  </NetworkSwitch>

  <NetworkSwitch>
    <ChannelID>A</ChannelID>
    <SwitchName>OPS2</SwitchName>
    <RackNumber>Fill</RackNumber>
    <Elevation>Fill</Elevation>
    <RoomLocation>Fill</RoomLocation>
   <NetworkSwitchConfigModule>switch_2_cle.txt</NetworkSwitchConfigModule>
    <Override>false</Override>
  </NetworkSwitch>

文件 2 - Networks_2.xml

<?xml version="1.0" encoding="utf-8"?>
<Network_Records xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Networks.xsd">
<NetworkSwitch>
    <ChannelID>A</ChannelID>
    <SwitchName>OPS1</SwitchName>
    <RackNumber>Fill</RackNumber>
    <Elevation>Fill</Elevation>
    <RoomLocation>Fill</RoomLocation>
    <NetworkModule>
      <ModuleNumber>2</ModuleNumber>
      <NetworkPort>
        <PortNumber>1</PortNumber>
        <DeviceType>Processor</DeviceType>
        <DeviceName>ASA1 (J5)</DeviceName>
      </NetworkPort>
      <NetworkPort>
        <PortNumber>10</PortNumber>
        <DeviceType>Processor</DeviceType>
        <DeviceName>CWA2 (J5)</DeviceName>
      </NetworkPort>
    </NetworkModule>
  </NetworkSwitch>
  <NetworkSwitch>
    <ChannelID>A</ChannelID>
    <SwitchName>OPS2</SwitchName>
    <RackNumber>REPLACE</RackNumber>
    <Elevation>REPLACE</Elevation>
    <RoomLocation>REPLACE</RoomLocation>
    <NetworkModule>
      <ModuleNumber>2</ModuleNumber>
      <NetworkPort>
        <PortNumber>1</PortNumber>
        <DeviceType>Processor</DeviceType>
        <DeviceName>ASA1 (J4)</DeviceName>
      </NetworkPort>
      <NetworkPort>
        <PortNumber>10</PortNumber>
        <DeviceType>Processor</DeviceType>
        <DeviceName>CWA2 (J7)</DeviceName>
      </NetworkPort>
    </NetworkModule>
  </NetworkSwitch>
</Network_Records>

到目前为止我的 XSLT -

<xsl:output method="xml" indent="yes" version="1.0" encoding="utf-8" />

<xsl:variable name="tempNetworks" select="document('Networks_2.xml')"/>

<xsl:template match="@* | node()">
    <xsl:copy>
        <xsl:apply-templates select="@* | node()" />
    </xsl:copy>
</xsl:template>

<xsl:template match="NetworkSwitchConfigModule">
   <xsl:copy-of select="$tempNetworks/Network_Records/NetworkSwitch/NetworkModule"/>
</xsl:template>

<xsl:template match="Override">
</xsl:template>

Answer 1

只需将您的模板更改为

<xsl:template match="NetworkSwitchConfigModule">
    <xsl:copy-of select="$tempNetworks/Network_Records/NetworkSwitch[SwitchName = current()/../SwitchName]/NetworkModule"/>
</xsl:template>

<xsl:template match="Override" />

您缺少 select 第二个 XML 正确节点的谓词。因此，您复制了所有 NetworkModule 元素，而不仅仅是您想要的元素。谓词

SwitchName = current()/../SwitchName

比较第二个文件的SwitchName与当前匹配的模板规则的父SwitchName的值。
