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.
Any help would be much appreciated.

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.

It looks to me that Björn's pattern achieves this. (Which filling in

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

The pipe(|) in you regular expression means 'or' right? If so then you
can only have the characters dgHhMmstyf,\-\./:;\\ OR characters in
quotes but not both in the same string so you can have:
dddd, d. MMMM yyyy
OR
'ab$olutN0n$en$ e'
But not
dddd, d. MMMM yyyy 'ab$olutN0n$en$ e'
Does this make sense?

But that's then wrapped in a set of brackets and a *. So you can have
any number of occurences of:
dddd, d. MMMM yyyy
OR
'ab$olutN0n$en$ e'
which means you can have:
dddd, d. MMMM yyyy 'ab$olutN0n$en$ e'
Note the pattern mentioned earlier is wrong. To match Bjorn's
suggestion it should not have had the first ^, so it becomes:
([ dgHhMmstyf,\-\./:;\\]|'[^']*')*
I recommend loading the pattern into whatever is the most convenient
regular expression parser for you such as Perl, PHP, Java, C#,
Javascript, and developing a number of test cases. Then check that
each one passes or fails as is appropriate. Then where there's
errors, list them here.
If you don't have a convenient regular expression engine locally you
might be able to download a pure regular expression tester, or do
something on the web such as: http://www.nvcc.edu/home/drodgers/ce...est_regexp.asp
BTW - when testing a regular expression destined for a schema on a
normal regular expression engine, remember to put ^ and $ anchors
around it.

Pete.

Hi,
I am replaceing a big string using different regular expressions (see
some example at the end of the message). The problem is whenever I
apply a "replace" it makes a new copy of string and I want to avoid
that. My question here is if there is a way to pass either a memory
stream or array of "find", "replace" expressions or any other way to
avoid multiple copies of a string.
Any help will be highly appreciated

I have a regular expression (^(.+)(?=\s*).*\1 ) that results in
matches. I would like to get what the actual regular expression is.
In other words, when I apply ^(.+)(?=\s*).*\1 to " HEART (CONDUCTION
DEFECT) 37.33/2 HEART (CONDUCTION DEFECT) WITH
CATHETER 37.34/2 " the expression is "HEART (CONDUCTION DEFECT)". How
do I gain access to the expression (not the matches) at runtime?
