在循环中使用TEI XML解析器

Question

我发现关于解析TEI的this文章在处理单个XML文件时非常有帮助。但是，我有一个完整的目录。我在dir中的循环没有执行，我不知道为什么。

from bs4 import BeautifulSoup
import os.path
import glob

tei_docs = "../input/tei-xml-files"
    def read_tei(tei_docs):
    os.chdir(tei_docs)
for i in glob.glob(os.path.join(tei_docs, "*.xml")):
    read_file(i)

def read_file(i):

with open(i, "r") as tei:
    soup = BeautifulSoup(tei, 'lxml')

soup.title.getText()

我得到了输出

NameError

回溯(最近一次调用)在

->1 soup.title.getText()

NameError:未定义名称“”soup“”

您的代码中有几个问题，包括缩进错误。我还用Beautiful Soup编写了一个脚本来读取XML文件中的标题，如下所示：

#!/usr/bin/env python
# coding: utf-8

from bs4 import BeautifulSoup
import os
from os.path import dirname, join
directory=("C:\\Users\\mbarg\\Documents\\corpus") # location of XML files on local drive

results=[] # create result list
for infile in os.listdir(directory):
    filename=join(directory, infile)
    indata=open(filename,"r", encoding="utf-8", errors="ignore") # UTF-8 encoding errors are ignored
    contents = indata.read()
    soup = BeautifulSoup(contents,'xml')
    titles = soup.find_all('title') # get item titles
    for title in titles:
        print(title.get_text())
        results.append(title.get_text())
print(results) # result list is shown on screen
