pythonを使用して引用キーに基づいてbibtexファイルから特定のエントリを削除するにはどうすればよいですか?私は基本的に2つの引数(bibtexファイルと引用キーへのパス)をとり、そのキーに対応するエントリをファイルから削除する関数が必要です。私は正規表現で遊んだが成功しなかった。私もbibtexパーサのために少し見えましたが、それは過剰なもののようです。下のスケルトン関数では、決定的な部分はcontent_modified =
です。ここでPythonを使用して引用キーに基づいてbibtexファイルから特定のエントリを削除する
def deleteEntry(path, key):
# get content of bibtex file
f = open(path, 'r')
content = f.read()
f.close()
# delete entry from content string
content_modified =
# rewrite file
f = open(path, 'w')
f.write(content_modified)
f.close()
(抽象的にスペースで)ファイルのBibTeX例です。

abstract = {The big-fish-little-pond effect {(BFLPE)} refers to the theoretical prediction that equally able students will have lower academic
self-concepts in higher-achieving or selective schools or programs than in lower-achieving or less selective schools or programs,
largely due to social comparison based on local norms. While negative consequences of being in a more competitive educational
setting are highlighted by the {BFLPE}, the exact nature of the {BFLPE} has not been closely scrutinized. This article provides
a critique of the {BFLPE} in terms of its conceptualization, methodology, and practical implications. Our main argument is that

編集:ここに私が思い付いたソリューションです。 bibtexエントリ全体を照合するのではなく、最初のすべての文字列@article{dai2008thebigfishlittlepond,
を探してから、コンテキスト文字列をスライスして対応するエントリを削除します。
content_keys = [(m.group(1), m.start(0)) for m in re.finditer("@\w{1,20}\{([\w\d-]+),", content)]
idx = [k[0] for k in content_keys].index(key)
content_modified = content[0:content_keys[idx][1]] + content[content_keys[idx + 1][1]:]
行頭で '}'を閉じることに依存しているので、中括弧を数えて項目の終わりを知る必要がありますか? –
