The regex that works is
有效的正则表达式是
\{\{\#lsth\:JointEntero_May_2015\|2015_May_([0-9]+)\}\}
It is working because the { and } characters must be escaped in order to get matched as literal symbols. {} are usually used as quantifiers where we can set min and/or max characters corresponding to the preceding pattern to match. See the documentation:
这是有效的,因为{和}字符必须被转义才能匹配为文字符号。 {}通常用作量词,我们可以设置与前一个模式相对应的最小和/或最大字符以匹配。查看文档:
{n}
Matchesncopies of the element it applies to.
{n,}
Matchesnor more copies of the element it applies to.
{m,n}
Matches m to n copies of the element it applies to, as much it can.
{n,}?,{m,n}?
Like the above, but match as few copies as they can. Compare with *? and friends.{n}匹配它适用的元素的n个副本。 {n,}匹配它适用的元素的n个或多个副本。 {m,n}尽可能匹配m到它应用的元素的n个副本。 {N,}?,{M,N}?像上面一样,但尽可能少地匹配副本。与之比较 *?和朋友。
