I have a regular expression that allows only certain characters to be
valid in an xml doc as follows:

<xs:pattern value="^[ dgHhMmstyf,\-\./:;\\]*" />

What I want to do is also allow any unicode character that is enclosed
in single quotes to also be valid, no matter where they appear. I
tried the following:

<xs:pattern value="^[ dgHhMmstyf,\-\./:;\\]*('*)*" />

But this only works if the characters in quotes appear after the other
text.

You are looking for "(a character from a certain set, or the character '
followed by zero or more characters except the character ' followed by
the character ') zero or more times", i.e. something like

([a-z]|'[^']*')*

if the first set of characters was a-z.

Not quite - I want to allow the character(s) in quotes to be able to
appear with the character(s) from the specified set but not in any
particular place i.e. not necessarily at the beginning or end. For
example, I want the following to be valid:

dddd, d. MMMM yyyy
dddd, d. MMMM MyYear
MyDay, d. MMMM yyyy
dddd, d. MyMonth yyyy

so MyDay, MyYear and MyMonth appear in single quotes in the xml file
and are valid.- Hide quoted text -

- Show quoted text -

It looks to me that Björn's pattern achieves this. (Which filling in
the dots would be:

(^[ dgHhMmstyf,\-\./:;\\]|'[^']*')*

Can you do a test program and show some examples where it does not
work?

Cheers,

Pete.
