我正在尝试使用 Beautiful Soup 从使用 Grobid 生成的 .tei.xml 文件中提取元素。

我可以使用以下方法获取标题：

titles = soup.findAll('title')

访问“较低级别”元素的正确语法是什么？（作者/单位等）

这是 tei.xml 文件的一部分，它是 Grobid 输出：

BeautifulSoup 将节点小写，这里有一些例子：

title = soup.html.body.teiheader.filedesc.analytic.title.string

for author in soup.html.body.teiheader.filedesc.sourcedesc.find_all('author'):
    tag_or_none = author.persname.forename
    first_affiliation = author.affiliation

另请参阅涵盖所有内容的 BeautifulSoup 文档。

我现在正在研究类似的问题并寻求合作。如果你想合作，请告诉我——sof@nconnor.com
