xml - RegEx to match a full string of various characters? -


i know question has been asked @ least 100 different times in @ least 100 different ways i'm struggling puzzle have found on create need.

i need regex can used inside xml pattern restriction tag matches these characters -

%&()"''*+,-./:;<=>?_#~@!$^[]{}0123456789abcdefghijklmnopqrstuvwxyz

as 1 full string, not sigle words or characters. can include spaces, not tab spaces or return key characters.

this have far - [a-za-z0-9$-/:-?@#{-~!^_\'\[\] *]

thanks in advance,

ash.

[..] character set, , match single character given in set. if want match while string, need repetition * match zero or more , + match one or more. since want match entire string need anchor expression, can ^ start of string , $ end of string.

so following regex match star of string one or more characters given set end of string:

^[a-za-z0-9$-/:-?@#{-~!^_\'\[\] *]+$

if interested in learning regex might want read on basics there lots of sites tons of information, such this one.

"banner style" seems poor use of space given outline view , quick outline functionality.
