Question

我试图在bibtex文件中搜索标题，仅将标题作为输出。

例如，当我逐行阅读bibtex文本时，它将是列表中的字符串：

['\tPages = {3221--52},\n',
 '\tTitle = {The slave trade and the origins of mistrust in Africa},\n',
 '\tVolume = {101},\n',
 '\tYear = {2011}}\n',
 '\n',
 '@article{perez2013regime,\n',
 "\tAuthor = {P{\\'e}rez-Li{\\~n}{\\'a}n, An{\\'\\i}bal and Mainwaring, Scott},\n",
 '\tDate-Added = {2019-03-06 15:28:11 -0800},\n',
 '\tDate-Modified = {2019-03-06 15:28:11 -0800},\n',
 '\tJournal = {Comparative Politics},\n',
 '\tNumber = {4},\n',
 '\tPages = {379--397},\n',
 '\tPublisher = {City University of New York},\n',
 '\tTitle = {Regime legacies and levels of democracy: evidence from Latin America},\n',
 '\tVolume = {45},\n']

从这里，我只想获取标题：

The slave trade and the origins of mistrust in Africa
Regime legacies and levels of democracy: evidence from Latin America

如何使用regex来做到这一点？

可能我想要类似的东西：

for line in lines:
    pattern = re.compile( regex here )
    result = pattern.search(line)
    if (result):
        print(result.group())

我按照以下答案进行操作，但不会显示结果：

string = '\tTitle = {Regime legacies and levels of democracy: evidence from Latin America},\n'
pattern = re.compile(r'^\\tTitle = \{(.*)\},\\n$')
result = pattern.match(string)
if (result):
    print(result.group(1))

我没有结果，意味着没有比赛？

Answer 1

尝试一下：

^\\tTitle = \{(.*)\},\\n$

使用匹配而不是搜索

使用正则表达式搜索结构相似的字符串
