Xml XSLT：将一个元素（包括子元素）复制到另一个节点中

我搜索了整个网络，但没有找到XML转换问题的解决方案。我有这样一个XML：

<?xml version="1.0" encoding="UTF-8"?>
<dataroot xmlns:od="urn:schemas-microsoft-com:officedata" generated="2016-04-06T10:00:04">

作为第一步，如果

paymentplan

中的名称标记合适，我想用带有父级

dataroot

的

paymentplan

标记替换每个站点标记中的

paymentplan

标记。这就是我被困的地方。有人能帮我吗，我对XSLT很陌生？非常感谢。

当前
付款计划
元素或相应
/dataroot/paymentplan
元素的
副本

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

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

<xsl:template match="paymentplan[local-name(..) = 'site']">
  <xsl:variable name="curUntersuchung" select="text()" />
  <xsl:choose>
    <xsl:when test="/dataroot/paymentplan[name/text() = $curUntersuchung]">
      <xsl:copy-of select="/dataroot/paymentplan[name/text() = $curUntersuchung]" />
    </xsl:when>
    <xsl:otherwise>
      <xsl:copy-of select="." />
    </xsl:otherwise>
  </xsl:choose> 
</xsl:template>   

</xsl:stylesheet>

我很难告诉您想要什么，因为您没有发布预期的输出XML。但从你的问题来看，我认为你想要转变

<site>
    <number>005</number>
    <name>Dr. ABC</name>
    <paymentplan>Laboruntersuchung</paymentplan>
    <studycode>STUDYXYZ</studycode>
</site>

对吗

如果是这样，那么您的XSL模板将是：

<xsl:template match="//site/paymentplan">
    <xsl:apply-templates select="ancestor::dataroot/paymentplan[name=current()]"/>
</xsl:template>

在这种情况下，您能显示预期的输出吗？非常感谢。
<site>
    <number>005</number>
    <name>Dr. ABC</name>
    <paymentplan>
        <code>LAB</code>
        <name>Laboruntersuchung</name>
        <service>PAR</service>
    </paymentplan>
    <studycode>STUDYXYZ</studycode>
</site>

<xsl:template match="//site/paymentplan">
    <xsl:apply-templates select="ancestor::dataroot/paymentplan[name=current()]"/>
</xsl:template>
