更换的话，包括串号

Question

t = "Text with numbers such as 58, 22nd, 53m2, number9 and foo44bar"

我想提出<span>的周围的数字是这样的：

t.gsub(/(\d+)([[:alnum:]]+)/,"<span>\\1\\2</span>") => 
"Text with numbers such as <span>58</span>, <span>22nd</span>, <span>53m2</span>, number9 and foo<span>44bar</span>" 

我仍然有唯一的问题是这个词的时候不启动像number9 and "foo<span>44bar</span>一些，我也试过

t.gsub(/([[:alnum:]]+)(\d+)([[:alnum:]]+)/,"<span>\\1\\2\\3</span>")，

但这也非q正确的。

我相信，我只是没有看到一些细节，一些帮助，将不胜感激:)

试试这个：

t.gsub(/([[:alnum:]]*(\d+)[[:alnum:]]*)/, "<span>\\1</span>")
