Bản mẫu này sử dụng Lua :
This string handling template returns the number of times that a pattern or search-string occurs in a source string. Counts non-overlapping matches only.
{{Str count|source string|pattern|plain_flag}}
If there is no occurrence of the source string in the pattern, this template returns 0.
There are three parameters; the first two are required:
|source= – the source string. Required; alias: |1=.|pattern= – the search-string or pattern to look for in the source string. Required; alias: |2=.|plain= – a boolean flag indicating that pattern should be understood as plain text and not as a Scribunto ustring pattern (a unicode-friendly Lua -style regular expression ). Optional; default: true.{{str count |aabbacccaddaeeeeaffff|a}} {{str count |0123456789ABCDEF|X}} {{str count |Wikipedia:Manual of Style/Words to watch|:}} {{str count |Wikipedia:Manual of Style/Words to watch|a}} {{str count |abababa|aba}}
