In classic regular expressions, there is the global search flag /g that forces a regex to find all possible matches in a string. In VBA, this flag is not supported. Instead, the VBA RegExp object provides the Global property that defines whether to search for all occurrences or only the ...
Empty matchesfor the patternsplitthe string only whennot adjacent to a previousempty match. 该句话的含义为:对于正则表达式模式中的空匹配,只有当其不与前一个空匹配相邻时,才会将其用于分割字符串。 具体来说,当正则表达式模式中存在连续的空匹配时,只有第一个空匹配会被用于分割字符串,后续的空匹配不会被...
