I need to be able to detect URIs in some text and after this replace
dem with HTML-anchors, that is http://www.tempuri.org/page.html
should be replaced with
<a href="http://www.tempuri.org/page.html">http ://www.tempuri.org/page.html</a>
I have made the following code:
re = new RegExp('(((http |https|ftp):\/\/)?\w+[.\w]+([^\w]*[\s]+))');
str = document.forms[0].longtext.value ; //textarea with text to replace
newstr = str.replace(re, '<a href="$1">$1</a>');
document.write( newstr);
However, it doesn't quite work as I would like it to. It seems to only
make a single match, and it seems to ingore leading and trailing
whitespaces.
Can you help me solving this?
I test of the code I have so far can be found at http://www.stocholm.dk/test/html/regexp.html
Thanks,
:o)

Try this regexp:
re = /(http|https|ftp )([^ ]+)/ig;
(The i at the end means ignore case, the g means global for multiple
matches)
This doesn't allow spaces in URL's (which isn't allowed anyway).

Try this regexp:

Forgot to mention that the replacement should be done as follows:
newstr = str.replace(re, '<a href="$1$2">$1$ 2</a>');

Step back from the technical part and answer this question:
What is an URL?
or more precisely:
What will you accept as an URL?
(The formal definition is in RFC2396
<URL:http://rfc.sunsite.dk/rfc/rfc2396.html>)
If you can answer it, in detail, then I bet it is easier to make a
regular expression to match it (or get help doing it, because then
the job is precisely specified).

Hello
Here's the thing
I have a database edited by some company workers editing descriptions of
books in the sotre , unfortunately these workers do not have the habit of
inserting a space character after word-ending dot, this is why i use the
function:
function getCorrect($txt) {
$txt=str_replace(",",", ",$txt);
$txt=str_replace(".",". ",$txt);

I need to browse a list of hyperlinks, each followed by an

to work.

Just a heads up for anybody that comes across this in the future.
Noticed a strange behavior in RegExp.test() today. Check out the
following code. It will alternately display "chokes" and null, as
every second call to .test() fails.
<script>
var str = "RegExp (chokes) on this every 2nd time";
var re = /chokes/g;

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));

This regexp
'<widget class=".*" id=".*">'
works well with 'grep' for matching lines of the kind
<widget class="GtkWindow" id="window1">
on a XML .glade file
However that's not true for the re module in python, since this one
takes the regexp as if were specified this way: '^<widget class=".*"

With regexps you can search for strings matching it. For example,
given the regexp: "foobar\d\d\d". "foobar123" would match. I want to
do the reverse, from a regexp generate all strings that could match
it.
The regexp: "{3}\d{3}" should generate the strings "AAA000",
"AAA001", "AAA002" ... "AAB000", "AAB001" ... "ZZZ999".
Is this possible to do? Obviously, for some regexps the set of matches

Hello all,
I have just discovered (the long way) that using a RegExp object with
the 'global' flag set produces inconsistent results when its test()
method is executed. I realize that 'global' is not an appropriate
modifier for the test() function - test() searches the entire string
by default.
However, I would expect it to degrade gracefully. Instead, I seem to
be getting something as follows - using W3Schools handy page at :

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

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,...
