Please match {my: abc} to <myname = "abc"/>

Please match {my: abc} to & lt; mynameabc & gt; and {my: abc}

$ Content = '{my: abc} {my: CBA} {my: 123} {sys: abc} {field: CBA} {tag: aaa }';


This write is invalid. please modify it.
$ Content = preg_replace ('/{(\ w. +) :( \ w. +)}/I ',' <$1 name = "$2"/> ', $ content );


Only the match starting with "my: sys: fled:" does not match any other matches.
The expected matching result is

{Tag: aaa}

Please reply after testing is feasible. thank you.

You can see the effect only when you look at the source code.
