xslt - 我想使用 XSL 文件将其转换为另一个 XML。但我无法删除我想要它的所有孩子

Question

输入 XML -

<?xml version="1.0"?>

<EsrOrder>
    <Header>
        <OrderId>
                865975
        </OrderId>
        <Metadata>
                None
        </Metadata>
    </Header>

    <ESRBody>
        <TN>
            6543219785
        </TN>
        <Tntype>
            Wireline
        </Tntype>
        <Priority>
            High
        </Priority>
        <TnOwnerName>
            Ching Chang
        </TnOwnerName>
        <TnAddress>
            <BasicAddress>
                101,Clssic View 44 Baikunth Dham Colony
            </BasicAddress>
            <Landmark>
                Near Anand Bazar
            </Landmark>
            <City>
                Indore
            </City>
            <State>
                Madhya Pradesh
            </State>
            <Country>
                India
            </Country>
        </TnAddress>
    </ESRBody>
</EsrOrder>

使用 XSLT -

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">



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

<xsl:template match="/">
<xsl:copy>
  <Sea_Element>
   <xsl:apply-templates/>
    </Sea_Element>
 </xsl:copy>

</xsl:template>

<xsl:template match="EsrOrder/Header">
      <xsl:copy-of select="@*|node()" />    
</xsl:template>

<xsl:template match="EsrOrder/ESRBody">
  <xsl:copy-of select="@*|node()" />    
</xsl:template>

<!--<xsl:template match="EsrOrder/ESRBody/TnAddress">
  <xsl:copy-of select="@*|node()" />    
</xsl:template>-->

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

 </xsl:stylesheet>

我得到的输出 -

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

        <OrderId>
                865975
        </OrderId>
        <Metadata>
                None
        </Metadata>



        <TN>
            6543219785
        </TN>
        <Tntype>
            Wireline
        </Tntype>
        <Priority>
            High
        </Priority>
        <TnOwnerName>
            Ching Chang
        </TnOwnerName>
        <TnAddress>
            <BasicAddress>
                101,Clssic View 44 Baikunth Dham Colony
            </BasicAddress>
            <Landmark>
                Near Anand Bazar
            </Landmark>
            <City>
                Indore
            </City>
            <State>
                Madhya Pradesh
            </State>
            <Country>
                India
            </Country>
        </TnAddress>

</Sea_Element>

哪里需要输出 -

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

        <OrderId>
                865975
        </OrderId>
        <Metadata>
                None
        </Metadata>



        <TN>
            6543219785
        </TN>
        <Tntype>
            Wireline
        </Tntype>
        <Priority>
            High
        </Priority>
        <TnOwnerName>
            Ching Chang
        </TnOwnerName>

            <BasicAddress>
                101,Clssic View 44 Baikunth Dham Colony
            </BasicAddress>
            <Landmark>
                Near Anand Bazar
            </Landmark>
            <City>
                Indore
            </City>
            <State>
                Madhya Pradesh
            </State>
            <Country>
                India
            </Country>


</Sea_Element>

它只是一个没有被淘汰的父字段。即使相同的代码适用于其他要删除的标签，我也能得到原因并纠正 XSL....

问题是使用copy-of阻止应用任何匹配内部元素的模板，例如TnAddress.

试试这个更简单的 XSLT：

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

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

  <!-- Elements that should be dropped - copying only their content -->
  <xsl:template match="EsrOrder|Header|ESRBody|TnAddress">
    <xsl:apply-templates select="@*|node()" />
  </xsl:template>

  <!-- Set the root element -->
  <xsl:template match="/">
    <xsl:copy>
      <Sea_Element>
        <xsl:apply-templates/>
      </Sea_Element>
    </xsl:copy>

  </xsl:template>

</xsl:stylesheet>
