I need a regular expression to validate the filename entered prior to this.I have looked on google where i found a couple but they didnt work.There are probably dozens of way to format a phone number.Your user interface should take care of the formatting problem by having a clear documentation on the format and/or split the phone into parts (area, exchange, number) and/or have an entry mask.I would just include the "\" character in the regular expression.You will need to escape it by putting another "\" before it. you will need to escape all the "\" characters in the above examples so that Java correctly incorporates them into the String.Unfortuntely regular expression syntax is a very foriegn langauge to me. any string that doesn't contain a slash is a valid filename.(Because of course, the slash must be a directory separator.) Any other character is valid in a file name -- asterisks, question marks, colons, tabs, line feeds, whatever.

So, when created via the Mac machine, file path and file name can have special characters like * @ $ ?The following expression is pretty lenient on the format and should accept 999-999-9999, 9999999999, (999) 999-9999.Make sure to be in global mode (g flag), case insensitive and to have the dot all option on.metacharacter match anything INCLUDING line breaks. Java Script by default does not support this since the . This is the best solution and should work 99% of the time is. If you want to match an IP within a string, get rid of the leading ^ and trailing $ to use \b (word boundaries) instead. The regular expression is only useful to validate the format of the date as entered by a user.Consult this page for more details on this problem. For the actual date validity, you should rely on another language.

If you need more examples or solutions, please contact me. Note that in character sets, special characters (., *, ) do not have any special meaning. This means match anything that is a single white space character OR anything that is not a white space character!
