使用xslt将多个字段合并为一个

Question

我有一个关于将多个节点合并到一个节点的问题。但我想不出该怎么做。

我有以下XML文件：

   <soap:Envelope xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"
               xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/"
               xmlns:s1="http://microsoft.com/wsdl/types/"
               xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/"
               xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
               xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/">
    <soap:Body>
        <RetrieveTicketUpdatesResponse>
            <RetrieveTicketUpdatesResult>
                <TicketUpdates>
                    <TicketUpdate>
                        <FreeFields>
                            <FreeField>
                                <FreeFieldID>9876</FreeFieldID>
                                <Value>Yes</Value>
                            </FreeField>
                        </FreeFields>
                        <FreeFields>
                            <FreeField>
                                <FreeFieldID>8765</FreeFieldID>
                                <Value>Fiber</Value>
                            </FreeField>
                        </FreeFields>
                        <Id>1234</ticketId>
                        <Status>New</status>
                    </TicketUpdate>
                    <TicketUpdate>
                        <TicketUpdate>
                        <FreeFields>
                            <FreeField>
                                <FreeFieldID>6823</FreeFieldID>
                                <Value>No</Value>
                            </FreeField>
                        </FreeFields>
                        <FreeFields>
                            <FreeField>
                                <FreeFieldID>3453</FreeFieldID>
                                <Value>Fiber</Value>
                            </FreeField>
                        </FreeFields>
                        <Id>2343</ticketId>
                        <Status>Update</status>
                    </TicketUpdate>
                </TicketUpdates>
            </RetrieveTicketUpdatesResult>
        </RetrieveTicketUpdatesResponse>
    </soap:Body>
</soap:Envelope>

我想将FreeFields节点合并到一个节点中，如下所示，并创建以下输出：

<soap:Envelope xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"
               xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/"
               xmlns:s1="http://microsoft.com/wsdl/types/"
               xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/"
               xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
               xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/">
    <soap:Body>
        <RetrieveTicketUpdatesResponse>
            <RetrieveTicketUpdatesResult>
                <TicketUpdates>
                    <TicketUpdate>
                        <FreeFields>
                            <FreeField>
                                <FreeFieldID>9876</FreeFieldID>
                                <Value>Yes</Value>
                            </FreeField>
                            <FreeField>
                                <FreeFieldID>8765</FreeFieldID>
                                <Value>Fiber</Value>
                            </FreeField>
                            <FreeField>
                                <FreeFieldID>7654</FreeFieldID>
                                <Value>https://www.stackoverflow.com</Value>
                            </FreeField>
                        </FreeFields>
                        <Id>1234</ticketId>
                        <Status>New</status>
                    </TicketUpdate>
                    <TicketUpdate>
                        <TicketUpdate>
                        <FreeFields>
                            <FreeField>
                                <FreeFieldID>6823</FreeFieldID>
                                <Value>No</Value>
                            </FreeField>
                            <FreeField>
                                <FreeFieldID>3453</FreeFieldID>
                                <Value>Fiber</Value>
                            </FreeField>
                            <FreeField>
                                <FreeFieldID>8563</FreeFieldID>
                                <Value>https://www.stackexchange.com</Value>
                            </FreeField>
                        </FreeFields>
                        <Id>2343</ticketId>
                        <Status>Update</status>
                    </TicketUpdate>
                </TicketUpdates>
            </RetrieveTicketUpdatesResult>
        </RetrieveTicketUpdatesResponse>
    </soap:Body>
</soap:Envelope>

我尝试使用xsl:for-each。然后把它复制到一个新的列表中，但是我想不出如何做到这一点。有人能帮我举个例子吗？我试着在谷歌上搜索解决方案，但没有找到解决方案。

更新1这是我正在使用的

  <!-- Stylesheet to inject namespaces into a document in specific places -->
  <xsl:template match="/">

  <!-- template to copy the rest of the nodes -->

Answer 1

尝试以下脚本：

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:soap="http://schemas.xmlsoap.org/soap">
  <xsl:output method="xml" omit-xml-declaration="yes" encoding="UTF-8" indent="yes" />
  <xsl:strip-space elements="*"/>

  <xsl:template match="TicketUpdate">
    <xsl:copy>
      <FreeFields>
        <xsl:copy-of select="FreeFields/FreeField"/>
      </FreeFields>
      <xsl:apply-templates select="*[name() != 'FreeFields']"/>
    </xsl:copy>
  </xsl:template>

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

您还必须更正源XML中的一些错误。
