使用bibtexparser解析bibTex

使用示例：

使用Python解析BibText引用格式-python黑洞网

# 生成示例bibtex文件

bibtex = """@ARTICLE{Cesar2013,
  author = {Jean César},
  title = {An amazing title},
  year = {2013},
  month = jan,
  volume = {12},
  pages = {12--23},
  journal = {Nice Journal},
  abstract = {This is an abstract. This line should be long enough to test
     multilines...},
  comments = {A comment},
  keywords = {keyword1, keyword2}
}
"""

with open('bibtex.bib', 'w') as bibfile:
    bibfile.write(bibtex)

# 处理bibtex文件

import bibtexparser

with open('bibtex.bib') as bibtex_file:
    bib_database = bibtexparser.load(bibtex_file)

print(bib_database.entries)

# 输出

import bibtexparser as bp
from bibtexparser.bparser import BibTexParser
from bibtexparser.customization import convert_to_unicode

with open('IEEE Proceeding.bib', encoding='UTF-8') as bibfile:
    parser = BibTexParser(common_strings=True)  # 声明解析器类
    parser.customization = convert_to_unicode  # 将BibTeX编码强制转换为UTF编码
    bibdata = bp.load(bibfile, parser)  # 通过bp.load()加载

# 输出所有的id
id_list = [item['ID'] for item in bibdata.entries]
