Regular Expression for Alphabetic Letter with accent

This might be a start

^([\w\d]+[ ]?)+$

\d matches the digits

\w matches "word characters". The.NET RegEx considers unicode characters as word characters. See: http://regexlib.com/CheatSheet.aspx

I'm not sure what you mean by "one white space". This expressions allows one space, but not double-spaces, between words.


If validation occurs at server side, you can use the pattern:

^\w*(\s\w*)?$

\w in .Net is Unicode aware - it should include all letters.

Note that \w also include the underscore and other word-connectors. You can use [\p{L}\p{Nd}] instead of \w to disallow them.

    [-'0-9a-zÀ-ÿ] allows dash, apostrophe, digits, letters, and chars in a wide accented range, from which we need to subtract The + matches that one or more times The $ anchor asserts that we are at the end of the string

    Regular Expressions for the Rest of Us. Sooner or later you'll run across a regular expression. With their cryptic syntax, confusing documentation and massive learning curve, most developers settle for copying and pasting them from StackOverflow and hoping they work.

    The @ character can be used directly in the pattern without escapement. It is not special at all since it has no meaning apart from being a printable character.

    Populate Test Alphabetic Data. The following script will add some test data that we will use to build and text the regular expressions. CREATE TABLE alphareg( Alphabetic VARCHAR(8000) ) INSERT INTO alphareg VALUES ('Two plus two equals four.') , ('But in Rome we must toe the line of fashion, spending beyond our means, and often on borrowed
