The RegEx below would match any query longer than X characters (70 in this case, but you can go down until you are happy with the results). In my case, I got some weird results, not worth optimizing for. Still, going down to 50, I got some very useful results. ^[\w\W\s\S]{...
preg_match() in PHP – this function is used to perform pattern matching in PHP on a string. It returns true if a match is found and false if a match is not found. preg_split() in PHP – this function is used to perform a pattern match on a string and then split the results in...

RegExFind will look for the first occurrence of a word or phrase that matches the regular expression. If a match is found, it continues processing by moving one word to the right of the result of RegExFind and acts on that word. If it is a date format, UpdateField will place the valu...

这里有一个解决方案，用正则表达式匹配字符串的某些部分，并用String.prototype.replace()删除它们。
Summary Metacharacters[and]are used to define sets of characters, any one of which must match (ORin contrast toAND). Character sets may be enumerated explicitly or specified as ranges using the-metacharacter. Character sets may be negated using^; this forces a match of anything but the specif...
将临时std::string传递给boost::regex_match 、、 我想把一个整数对字符串解析成数字。我使用以下代码: #include <iostream> #include <boost/regex.hpp> int main() { boost::regex reg( "(\\d+):(\\d+)" ); std::string test = "1:2 3:4 5:6"; boost::sregex_token_iterator end; f...
