用美汤解析Grobid .tei.xml输出

Question

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。

我可以使用以下命令获取标题：

titles = soup.findAll('title')

访问“较低级别”元素的正确语法是什么？(作者/所属单位等)

这是作为Grobid输出的tei.xml文件的一部分：

BeautifulSoup将节点小写，下面是一些示例：

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

还有see the BeautifulSoup documentation，它涵盖了所有内容。

我现在正在解决一个类似的问题，并寻求合作。如果你想组队，请告诉我-- sof@nconnor.com
