为XMLusing XSLT的同一层次结构中的多个子节点添加父节点

Question

我有一个场景，我的输入如下所示，需要解析的Xml无效，下面添加的预期输出可以帮助我获得所需的输出

<MessageHeader>
     <ServiceInitiatorKey>000</ServiceInitiatorKey>
     <ServiceProviderKey>SADAD-001</ServiceProviderKey>
     <ServiceConsumerId>000</ServiceConsumerId>
     <RqUID>4lkuo5bi-8e98-8bnn-32ge-ep3a6eiss241</RqUID>
     <Date>2020-00-00T00:00:00</Date>
     <Lang>en-gb</Lang>
  </MessageHeader><LoadRq>
     <Timestamp>2020-00-00T00:00:00</Timestamp>
     <Payment>
        <BillerId>000</BillerId>
        <CurAmt>0</CurAmt>
     
        <PrcDt>2020-00-00T00:00:00</PrcDt>
        <DueDt>2020-00-00T00:00:00</DueDt>
        <BillerPmtId>000000</BillerPmtId>
        <PaymentRef>
           <BillNumberWithAccount>
              <BillingAcct>0000000000</BillingAcct>
              <BillNumber>0000000000</BillNumber>
           </BillNumberWithAccount>
           
        </PaymentRef>
     </Payment>
  </LoadRq>

预期输出如下所示

<?xml version="1.0" encoding="UTF-8"?>
<root>
<MessageHeader>
     <ServiceInitiatorKey>000</ServiceInitiatorKey>
     <ServiceProviderKey>SADAD-001</ServiceProviderKey>
     <ServiceConsumerId>000</ServiceConsumerId>
     <RqUID>4lkuo5bi-8e98-8bnn-32ge-ep3a6eiss241</RqUID>
     <Date>2020-00-00T00:00:00</Date>
     <Lang>en-gb</Lang>
  </MessageHeader><LoadRq>
     <Timestamp>2020-00-00T00:00:00</Timestamp>
     <Payment>
        <BillerId>000</BillerId>
        <CurAmt>0</CurAmt>
     
        <PrcDt>2020-00-00T00:00:00</PrcDt>
        <DueDt>2020-00-00T00:00:00</DueDt>
        <BillerPmtId>000000</BillerPmtId>
        <PaymentRef>
           <BillNumberWithAccount>
              <BillingAcct>0000000000</BillingAcct>
              <BillNumber>0000000000</BillNumber>
           </BillNumberWithAccount>
           
        </PaymentRef>
     </Payment>
  </LoadRq>

Answer 1

在XSLT/XPath3中有一个函数parse-xml-fragment，所以使用例如

<xsl:template name="xsl:initial-template">
  <root>
    <xsl:sequence select="parse-xml-fragment(unparsed-text('your-file.xml'))"/>
  </root>
</xsl:template>

应该允许你添加一个包装器元素。您将使用指定的模板开始转换(例如，Saxon9/10的-it命令行选项)。
