正则表达式是这里的方法，只要你保证模式不会改变或你制作一个更具适应性的正则表达式。

让我们将blob按摩成更容易管理的东西：
stri_replace_all_regex(
text,
"([[:alpha:][:space:]\\-]+ \\(born [[:alpha:]]+ [[:digit:]]+, [[:digit:]]+\\):)",
"\n$1\n"
) %>%
stri_split_lines() %>%
flatten_chr() %>%
discard(`==`, "") %>%
stri_trim_both() -> lines
lines现在看起来像这样：
lines
## [1] "Jeon Bo-ram (born March 22, 1986):"
## [2] "She, better known mononymously as Boram, is a South Korean singer and actress. She is best known as a member of the South Korean girl group T-ara."

正则表达式查找名称和日期模式并将其拆分。这种“过度分裂”，但discard()负责空白行。
现在我们有了名称/ dob的行对和描述，并且可以使用“by 2”索引迭代它们：
starts <- seq(1, length(lines), 2)
ends <- starts + 1
map2_df(starts, ends, ~{
stri_split_fixed(lines[.x], "(")[[1]] %>%
stri_replace_all_fixed("):", "") %>%
stri_replace_all_fixed("born ", "") -> name_dob
data_frame(
name = name_dob[1],
born = name_dob[2],
detail = lines[.y]
)
}) -> xdf
内部区块的第一部分分离＆amp;清理名称/ dob。后者生成一个数据框行，purrr的{{1}}将整个事物转换为数据框：
map2_df()如果您正在处理可能导致数千行的大型文本博客，那么使用glimpse(xdf)
## Observations: 4
## Variables: 3
## $ name <chr> "Jeon Bo-ram ", "Taylor Alison Swift ", "Nickolas Gene Carter ",...
## $ born <chr> "March 22, 1986", "December 13, 1989", "January 28, 1980", "Octo...
## $ detail <chr> "She, better known mononymously as Boram, is a South Korean sing...
vs list()（内部块的最后一部分）将更快并且消耗更少的临时内存
现在，可能有可能创建一个单一的正则表达式来查找每个三元组并提取它们，但是如果他们倾向于创建那些可能难以理解的野兽，我会让其他人展示他们的l33t正则表达式技能。 / p>

使用正则表达式
A <- unlist(strsplit(text, "[(](?=b)|[)]:|(?<=\\.) (?=[^.]+?\\(b)", perl=TRUE))
B <- sapply(A, function(i) trimws(i, "both"))
as.data.frame(matrix(B, ncol=3, byrow=TRUE))
