给定以下 xml 文件，我只需要选择具有 a 的记录 <marc:datafield tag="911"，并且在每个记录中911，仅提取具有代码 h 或 j:<marc:subfield code="h">或<marc:subfield code="j">. 两者都可以有文本值，即数字和文本。那么选择的记录和元素应该会改变，所以我们保持001的值为RECNO，并且我们添加一个唯一的RECORD ID增量值，从1开始。如果不存在h或j，则记录没有对应的元素. Name_1 是, and Name_2 is the new element name for`的新元素名称

我没有看到任何真正的分裂，您似乎只是想将元素映射record/datafield[subfield/@code = ('h', 'j')]到RECORD元素，然后将subfield元素映射到NAME_1/NAME_2元素：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xpath-default-namespace="http://www.loc.gov/MARC21/slim"
    expand-text="yes"
    exclude-result-prefixes="#all"
    version="3.0">

  <xsl:output indent="yes"/>

  <xsl:template match="/*">
      <xsl:copy>
          <xsl:copy-of select="@*"/>
          <xsl:apply-templates select="record/datafield[subfield/@code = ('h', 'j')]"/>
      </xsl:copy>
  </xsl:template>

  <xsl:template match="datafield">
      <RECORD ID="{position()}">
          <RECNO>{ancestor::record/controlfield}</RECNO>
          <xsl:apply-templates select="subfield[@code = ('h', 'j')]"/>
      </RECORD>
  </xsl:template>

  <xsl:template match="subfield[@code = 'h']">
      <NAME_1>{.}</NAME_1>
  </xsl:template>

  <xsl:template match="subfield[@code = 'j']">
      <NAME_2>{.}</NAME_2>
  </xsl:template>

</xsl:stylesheet>
