首先定义一些辅助函数
def isint(string):
try:
int(string)
except:
return False
return True
def get_char_only(string):
s = ""
for c in string:
if 'a' <= c <= 'z' or 'A' <= c <= 'Z':
s += c
return s
def is_char_only(string):
for c in string:
if not ('a' <= c <= 'z' or 'A' <= c <= 'Z'):
return False
return True
def is_charblank_only(string):
for c in string:
if not ('a' <= c <= 'z' or 'A' <= c <= 'Z' or c == ' '):
return False
return True
def has_dash(string):
for c in string:
if not c == '-':
return True
return False
定义一些类，从bib文件的组成部分依次构建

接下来就可以随意转换了：
t = Bib('''@article{DBLP:journals/corr/ChenG16,
author = {Tianqi Chen and
Carlos Guestrin},
title = {XGBoost: {A} Scalable Tree Boosting System},
journal = {CoRR},
volume = {abs/1603.02754},
year = {2016},
url = {http://arxiv.org/abs/1603.02754},
archivePrefix = {arXiv},
eprint = {1603.02754},
timestamp = {Mon, 13 Aug 2018 16:47:00 +0200},
biburl = {https://dblp.org/rec/journals/corr/ChenG16.bib},
bibsource = {dblp computer science bibliography, https://dblp.org}
}''')
print(t.to_buaa())
Chen T, Guestrin C. XGBoost: {A} Scalable Tree Boosting System[J]. CoRR, 2016, abs/1603.02754:Unknown.
注意bib格式中没出现页数信息，故最后一个显示Unknown，一般直接去掉就好。
