REG_NOTEOL:'$' 不被匹配,除非regcomp()的cflags参数指定REG_NEWLINE; 输出:匹配正常则返回0;否则返回错误信息(非0)。 regerror():输出错误信息; regfree():释放正则表达式。 示例分析 #include<stdint.h>#include<stdio.h>#include<stdlib.h>#include<regex.h>#
REG_NOSUB 不用存储匹配后的结果。 REG_NEWLINE 识别换行符,这样'$'就可以从行尾开始匹配,'^'就可以从行的开头开始匹配。 #include <stdio.h>#include<regex.h>#include<string.h>intmain() {constchar*pattern ="reg[a-z]";charbuf[128], lbuf[128] ="regbkdhkrega";intindex, cflags =0; rege...
search("dog", 1) # No match; search doesn't include the "d" Pattern.match(string[, pos[, endpos]]) 如果string 的开始位置 能够找到这个正则样式的任意个匹配,就返回一个相应的 匹配对象。如果不匹配,就返回 None ;注意它与零长度匹配是不同的。 可选参数 pos 和endpos 与search() 含义相同。

Additionally, it ignores characters in-between and including an un-escaped hash/pound (#) character and the next new line, so that you may include comments in complicated patterns. This only applies to data characters; white space characters may never appear within special character sequences in...
