I'm working on a project (Atox) where I need to match quite a few
regular expressions (several hundred) in reasonably large text files.
I've found that this can easily get rather slow. (There are many
things that slow Atox down -- it hasn't been designed for speed, and
any optimizations will entail quite a bit of refactoring.)
I've tried to speed this up by using the same trick as SPARK, putting
all the regexps into a single or-group in...

I recently upgraded to 4.1 alpha (MySQL 4.1.0-alpha-standard-log) on
my Linux server, and came across a problem with a query that had been
working in 3.23 that no longer worked in 4.1a. I've simplified the
query to demonstrate the problem:
select trim(upper('foo')) regexp ('^foo$') as trimUpper,
upper('foo') regexp ('^foo$') as justUpper,
trim('foo') regexp ('^foo$') as justTrim,
trim(upper('foo')) as trimUpperFoo,

I was reading my O'Reilly JavaScript The Definitive Guide when I came
across RegExp and thought I could tighten up my JavaScript code that
checks for a valid email address. Why does the following not appear to work:
var email_address = "Joe@Schmoe";
var email_regex = new RegExp ("^(\\w+)(\@)(\\w+)(\.)(\\w+)$");
var result = email_regex.exec (email_address);
alert (" result = \"" + result + "\"\n" +
" result = \"" + result + "\"\n" +

I am trying to figure out how to set up my reg exp search so that the search
will only match on the exact word.
Here is the current problem code:
Word1 = "RealPlayer.exe"
Word2 = "Player.exe"
RegExp re = Word2;
if (re.Find(Word1))

hello,
I have the problem writing the regular expression to verify the valid
system path in the way that RegExp.$1 has to contain path up to the
parent folder of a file, and RegExp.$2 should contain a file name (or be
empty if there was no file in the path). The allowed characters are all
except \ / : * ? " < > | The problem I have is to find a smart way to
separate the file part from the rest of the path.. could you give me
some hints...

I'm trying to set up client side validation for a textarea form element to
ensure that the data entered does not exceed 200 characters. I'm using the
following code but it doesn't seem to be working correctly:
if( this.value != '' ) {
if( !( RegExp( '^{0,200}$' ).test( this.value ))) {
alert( 'Information provided must not be more than 200 characters.' );
this.focus();
}

I need to come up with a function
function regExpPos (text, re, parenNum) { ... }
that will return the position within text of RegExp.$parenNum if there
is a match, and -1 otherwise.
For example:
var re = /some(thing|or other)?.*(n(est)(?:ed)?.*(parens) )/
var text = "There were some nesting parens in the test";
alert (regExpPos (text, re, 3));

Hello
I am looking for python code that takes as input a list of strings
(most similar,
but not necessarily, and rather short: say not longer than 50 chars)
and that computes and outputs the python regular expression that
matches
these string values (not necessarily strictly, perhaps the code is able
to determine
patterns, i.e. families of strings...).

Hi All,
I have encountered problems with JS RegExp.exec() and can't find what
is the problem. Could you help me?
formRequest is a function that extracts some information from
XMLHTTPRequest response. A very strange effect (and I can't find where
I've done something wrong) is that regexp matches in this function fail
on every second call.

Hello,
It seems delimiters can cause trouble sometimes.
Look at this :
<script type="text/javascript">
function isDigit(s) {
var DECIMAL = '\\.';
var exp = '/(^?0(' + DECIMAL

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
