xml - 我想根据条件使用 XSLT 删除 xml 标记

Question

我想根据一个条件从以下 xml 文件中删除 biilingbatch 中的“centrum”标签。条件是如果是 1921 那么我想从 XML 中删除 centrum 标签。在xml中，不同的Parent标签下有很多centrum标签。我想删除那个父标签是 billingbatch 的 centrum 标签。我的 xml 是:

<calculate>
        <calculateAmount>
          <currency>978</currency>
          <individualAmount>-10000</individualAmount>
          <billingType>1</billingType>
          <billingPeriodEndDate>20260214</billingPeriodEndDate>
          <extMvmtFinInstMode>8</extMvmtFinInstMode>
        <billingbatch>
                        <Account>1921</Account>
                        <Centrum>LBNG</Centrum>
                        <Company>LNS</Company>
                        <TextCode>570</TextCode>
                        <TextData>952491</TextData>
        </billingbatch>

        <calculatebillingbatch>
                <Account>1921</Account>
                        <Centrum>LBNG</Centrum>
                        <Company>LNS</Company>
                        <TextCode>570</TextCode>
                        <TextData>952491</TextData>
        </calculatebillingbatch>
        </calculateAmount>

预期结果是:

<calculate>
        <calculateAmount>
          <currency>978</currency>
          <individualAmount>-10000</individualAmount>
          <billingType>1</billingType>
          <billingPeriodEndDate>20260214</billingPeriodEndDate>
          <extMvmtFinInstMode>8</extMvmtFinInstMode>
        <billingbatch>
                        <Account>1921</Account>                             
                        <Company>LNS</Company>
                        <TextCode>570</TextCode>
                        <TextData>952491</TextData>
        </billingbatch>

        <calculatebillingbatch>
                <Account>1921</Account>
                        <Centrum>LBNG</Centrum>
                        <Company>LNS</Company>
                        <TextCode>570</TextCode>
                        <TextData>952491</TextData>
        </calculatebillingbatch>
        </calculateAmount>

好好使用恒等变换模板

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

和模板

<xsl:template match="billingbatch[Account = 1921]/Centrum"/>
