xml - XSLT - 在展平 xml 后组合多个属性(连接)

Question

我有一个要展平的简单 xml(元素到属性)

输入xml

<?xml version="1.0" ?>
<queryResponse type="Clients" rootUrl="https://10.130.0.192/webacs/api/v1/data" requestUrl="https://10.30.0.192/webacs/api/v1/data/Clients?.full=true&amp;.firstResult=0&amp;.maxResults=1000" responseType="listEntityInstances" count="349" first="0" last="348">
  <entity url="https://10.130.0.192/webacs/api/v1/data/Clients/621621" type="Clients" dtoType="clientsDTO">
    <clientsDTO id="621621" displayName="621621">
      <associationTime>1474746255456</associationTime>
      <clientInterface>GigabitEthernet1/0/16</clientInterface>
      <connectionType>WIRED</connectionType>
      <deviceIpAddress>10.1.1.254</deviceIpAddress>
      <deviceName>stack</deviceName>
      <deviceType>Unknown</deviceType>
      <ipAddress>10.30.0.106</ipAddress>
      <location>Unknown</location>
      <macAddress>macaddress</macAddress>
      <protocol>DOT3</protocol>
      <securityPolicyStatus>PASSED</securityPolicyStatus>
      <status>ASSOCIATED</status>
      <updateTime>1474746256758</updateTime>
      <vendor>Netapp</vendor>
      <vlan>vlan_300_server</vlan>
      <vlanId>300</vlanId>
    </clientsDTO>
  </entity>
 </queryResponse>

xslt:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="queryResponse">
    <Data>
      <xsl:apply-templates/>
    </Data>
  </xsl:template>

  <xsl:template match="clientsDTO">
    <Client>
      <xsl:for-each select="descendant::*[not(*)]">
        <xsl:attribute name="{name()}">
          <xsl:value-of select="text()"/>
        </xsl:attribute>

      </xsl:for-each>
    </Client>
  </xsl:template>
</xsl:stylesheet>

它工作正常并为我提供了扁平化的输出 xml。

现在有了这个 XSLT，我想再添加一件事。 元素 clientInterface 和 deviceName 需要(另外)连接为一个新属性。

关于如何实现这一点有什么想法吗？

更新:

我当前的输出 xml 如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<Data>
   <Client associationTime="1474746255456" clientInterface="GigabitEthernet1/0/16" connectionType="WIRED" deviceIpAddress="10.1.1.254" deviceName="stack" deviceType="Unknown" ipAddress="10.130.0.106" location="Unknown" macAddress="macaddress" protocol="DOT3" securityPolicyStatus="PASSED" status="ASSOCIATED" updateTime="1474746256758" vendor="Netapp" vlan="vlan_300_server" vlanId="300" />
</Data>

现在在那个“我想有一个新的属性，它连接 deviceName 和 clientInterface 导致:

<?xml version="1.0" encoding="UTF-8"?>
<Data>
   <Client **deviceId="stack_GigabitEthernet1/0/16"**associationTime="1474746255456" clientInterface="GigabitEthernet1/0/16" connectionType="WIRED" deviceIpAddress="10.1.1.254" deviceName="stack" deviceType="Unknown" ipAddress="10.130.0.106" location="Unknown" macAddress="macaddress" protocol="DOT3" securityPolicyStatus="PASSED" status="ASSOCIATED" updateTime="1474746256758" vendor="Netapp" vlan="vlan_300_server" vlanId="300" />
</Data>

Answer 1

你可以这样做:

<xsl:template match="clientsDTO">
    <Client>
        <xsl:attribute name="deviceId">
            <xsl:value-of select="deviceName"/>
            <xsl:text>_</xsl:text>
            <xsl:value-of select="clientInterface"/>
        </xsl:attribute>
        <xsl:for-each select="*[not(*)]">
            <xsl:attribute name="{name()}">
                <xsl:value-of select="."/>
            </xsl:attribute>
        </xsl:for-each>
    </Client>
</xsl:template>

注意:使用 descendant 轴效率低下 - 在您的情况下也没有必要。
