我有这样的事情:
Othername California (2000) (T) (S) (ok) {state (#2.1)}
是否需要获取正则表达式代码:
Othername California ok 2.1
即。我想将数字保持在圆括号内,而这些数字依次在{}内,并保持文本“ok”在()内。 我特别需要字符串“ok”打印出来,如果包含在我的行中,但我想摆脱括号内的其他文本,例如(V),(S)或(2002)。
我知道可能正则表达式不是解决此类问题的最有效方法。
任何帮助都将不胜感激。
编辑:
字符串可能会有所不同,因为如果某些信息不可用,则不包含在该行中。文本本身也是可变的(例如,每行都没有“状态”)。例如,人们可以拥有:
Name1 Name2 Name3 (2000) (ok) {edu (#1.1)}
Name1 Name2 (2002) {edu (#1.1)}
Name1 Name2 Name3 (2000) (V) {variation (#4.12)}

(.+)\s+\(\d+\).+?(?:\(([^)]{2,})\)\s+(?={))?\{.+\(#(\d+\.\d+)\)\}
Name1 Name2 Name3 (2000) {Education (#3.2)} Name1 Name2 Name3 (2000) (ok) {edu (#1.1)} Name1 Name2 (2002) {edu (#1.1)} Name1 Name2 Name3 (2000) (V) {variation (#4.12)} Othername California (2000) (T) (S) (ok) {state (#2.1)}
>>> regex = re.compile("(.+)\s+\(\d+\).+?(?:\(([^)]{2,})\)\s+(?={))?\{.+\(#(\d+\.\d+)\)\}") >>> r = regex.search(string) >>> r <_sre.SRE_Match object at 0x54e2105f36c16a48> >>> regex.match(string) <_sre.SRE_Match object at 0x54e2105f36c169e8> # Run findall >>> regex.findall(string) [ (u'Name1 Name2 Name3' , u'' , u'3.2'), (u'Name1 Name2 Name3' , u'ok', u'1.1'), (u'Name1 Name2' , u'' , u'1.1'), (u'Name1 Name2 Name3' , u'' , u'4.12'), (u'Othername California', u'ok', u'2.1') ]

试试这个:
import re
thestr = 'Othername California (2000) (T) (S) (ok) {state (#2.1)}'
regex = r'''
([^(]*) # match anything but a (
\ # a space
(?: # non capturing parentheses
\([^(]*\) # parentheses
\ # a space
){3} # three times
\(([^(]*)\) # capture fourth parentheses contents
\ # a space
{ # opening {
[^}]* # anything but }
\(\# # opening ( followed by #
([^)]*) # match anything but )
\) # closing )
} # closing }
'''
match = re.match(regex, thestr, re.X)
print match.groups()
输出:
('Othername California', 'ok', '2.1')
这是压缩版本:
import re
thestr = 'Othername California (2000) (T) (S) (ok) {state (#2.1)}'
regex = r'([^(]*) (?:\([^(]*\) ){3}\(([^(]*)\) {[^}]*\(\#([^)]*)\)}'
match = re.match(regex, thestr)
print match.groups()

尽管我在评论中已经说过了。我找到了解决方法:
(?(?=\([^()\w]*[\w.]+[^()\w]*\))\([^()\w]*([\w.]+)[^()\w]*\)|.)(?=[^{]*\})|(?<!\()(\b\w+\b)(?!\()|ok
<强>解释强>
(? # If
(?=\([^()\w]*[\w.]+[^()\w]*\)) # There is (anything except [()\w] zero or more times, followed by [\w.] one or more times, followed by anything except [()\w] zero or more times)
\([^()\w]*([\w.]+)[^()\w]*\) # Then match it, and put [\w.] in a group
| # else
. # advance with one character
) # End if
(?=[^{]*\}) # Look ahead if there is anything except { zero or more times followed by }
| # Or
(?<!\()(\b\w+\b)(?!\() # Match a word not enclosed between parenthesis
| # Or
ok # Match ok

其他情况是:
^(\w+\s?\w+)\s?\(\d{1,}\)\s?\(\w+\)\s?\(\w+\)\s?\((\w+)\)\s?.*#(\d.\d)
