Answer 1

进行一些调整以使您的输入和预期输出格式正确，我建议使用以下 XSLT 2.0 解决方案。调整是:

1. 将每个输入文档封装到单个节点中。
2. 将预期的输出文档封装到单个节点中。

因此，要转换以下文档....

<organization>
 <info>
  <organization_id>123</organization_id>
  <total_patients>5</total_patients>
 </info>
 <patients>
  <patient>
    <guid>1111</guid>
   </patient>
  <patient>
    <guid>2222</guid>
   </patient>
 </patients>
</organization>

包括以下共同输入文档...

<organization>
 <info>
  <organization_id>456</organization_id>
  <total_patients>10</total_patients>
 </info>
 <patients>
  <patient>
    <guid>3333</guid>
   </patient>
  <patient>
    <guid>4444</guid>
   </patient>
 </patients>
</organization> 

...将在您调用 XSLT 引擎时将其作为名称为“org2”的参数进行引用，应用以下 XSLT2 转换...

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:fn="http://www.w3.org/2005/xpath-functions"
  xmlns:xs="http://www.w3.org/2001/XMLSchema"
  version="2.0"
  exclude-result-prefixes="xsl xs fn">

<xsl:output indent="yes" encoding="UTF-8" />
<xsl:param name="org2" />
<xsl:variable name="org2-doc" select="document($org2)" />

<xsl:template  match="/">
 <output>
  <info>
   <total_patients>
    <xsl:number value="organization/info/total_patients +
             $org2-doc/organization/info/total_patients" />
   </total_patients>
  </info>
   <organizations>
    <xsl:apply-templates />
    <xsl:apply-templates select="$org2-doc/*" />
   </organizations>
 </output>
</xsl:template>

<xsl:template  match="organization">
  <organization>
   <organization_id>
    <xsl:number value="info/organization_id" />
   </organization_id>
   <xsl:copy-of select="patients" />   
  </organization>
</xsl:template>

</xsl:stylesheet>

... 产生期望的结果....

<?xml version="1.0" encoding="UTF-8"?>
<output>
   <info>
      <total_patients>15</total_patients>
   </info>
   <organizations>
    <organization>
       <organization_id>123</organization_id>
       <patients>
          <patient>
             <guid>1111</guid>
          </patient>
          <patient>
             <guid>2222</guid>
          </patient>
       </patients>
    </organization>
    <organization>
       <organization_id>456</organization_id>
       <patients>
          <patient>
             <guid>3333</guid>
          </patient>
          <patient>
             <guid>4444</guid>
          </patient>
       </patients>
    </organization>
   </organizations>
</output>
