I tried to create a pattern to validate a text box. Seemed harmless
enough until i put an apostrophe in my equation! It didn't work, IP
said I had an inavlid expression.

Here's what I used: [\w\s ']*

And IP didn't like it!
I even tried to escape it: [\w\s \']*
but no! IP still did not like it.

If anyone has found a resolution to this problem, I would definiately
like to hear about it! I really need to filter a lot of chars -EXCEPT-
the apostrophe.

Thank you!
Matt

Hi Matt,

Aposttrophes and Quotations are valid regular expression characters. My
guess is that Infopath won't like them because they will break xml
attributes, which use either ' or " to mark off the start and end of an
attribute.

The blog below has code solution (which is not ideal). Code is required as
Infopath treats escaped unicode/ascii character sequences as invalid:
