这是上一篇文章的后续问题。我正在使用一组图书馆目录记录（MARC XML格式），我想使用一个名为OpenRefine的工具对其进行清理和增强。OpenRefine 不能很好地处理 XML 数据，因此我需要将 MARC XML 转换为 TSV。

我之前帖子的解决方案帮助我做到了这一点。但是，一旦我从 OpenRefine 导出，我需要将数据往返返回到 MARC XML。OpenRefine 的输出比典型的 TSV 更复杂：单个记录可以跨多行分布，因为某些字段是可重复的：

这基本上给了我我需要的东西，但它并不灵活，并且使用这种方法来解释源数据中所有可能的变化将是一项挑战。

相反，我想修改xsl:analyze-string正则表达式，以便预先处理这个更复杂的制表​​符分隔结构。基本上，每次有“领导者”的价值时，都应该有一个新的记录。出现在后续行中的各个值应被解析为单独的 XML 元素，如下所示：

我对您的 XSLT 做了一些小的调整，输出与您发布的非常接近。有2个不同。

  1. 文本“ This volume is a collection of paper ... ”是“ This volume is a ... ”，因为“ collection of paper ”不在输入中

  2. 倒数第三个marc:datafield将子字段组合在一起。这是因为@name是相同的，并且 grouping-key() 不是以 6 开头的。不确定这是否正确。

可能是错误的数据字段：

<marc:datafield tag="700" ind1="1" ind2=" ">
   <marc:subfield code="a">Noether, Emmy</marc:subfield>
   <marc:subfield code="4">aut</marc:subfield>
   <marc:subfield code="a">Hasse, Helmut</marc:subfield>
   <marc:subfield code="4">aut</marc:subfield>
</marc:datafield>

这是生成所需输出的 ​​XSLT 的更新版本。field我的观点是在转换XML时应该处理数据字段中的任何变化。我认为对 XML 的调整比尝试修改正则表达式更容易。
