help with regex

[Petra Meier]

Hello,

I use the following script to parse URI and email:

function parseLinks($sDa ta){
$regexEmail = "/\w+((-\w+)|(\.\w+))*\ @[A-Za-z0-9]+((\.|-)[A-
Za-
z0-9]+)*\.[A-Za-z0-9]+/";
$sData = preg_replace($r egexEmail, "<a id='external'
href='mailto:'$ 0'>$0</a>", $sData);
$regexURI = '#(^|[^\"=]{1})(http://|ftp://|https://|news:)([^
\s<>]+)
([\s\n<>]|$)#sm';
$sData = preg_replace($r egexURI, "\\1<a id=\"external\" name=
\"\\2\
\3\">\\2\\3</a>\\4", $sData);
return $sData;

}

it works just fine, unfortunately I parse the links from texts where I
have fullstops, commas, colons and semicolos at the end of URI which
are parsed as part of the URI:

A sentence with a link http://uri.in.senctence.com/foo.html, and a
comma after the link

would be parsed to:

A sentence with a link <a href="http://uri.in.senctenc e.com/
foo.html,">http ://uri.in.senctenc e.com/foo.html,<a/and a comma after
the link

I want to have it like this though:

A sentence with a link <a href="http://uri.in.senctenc e.com/
foo.html">http://uri.in.senctenc e.com/foo.html<a/>, and a comma after
the link

I already invested a lot of time with these regex and didn't succeed.
Any of you regex-gurus could help me please! :)

Petra,
Not a regex-expert, and not absolutely clear from your description exactly
what you want, but for what its worth and as you have had no other reply,
perhaps:-

$regexURI =
'#(^|(?<=>))(ht tp://|ftp://|https://|news:)([^\s]+(htm)l?)?([\.,;:]?|$)#sm';

$repString = "$1<a id=\"external\" name=\"$2$3\">$ 2$3</a>$5";

Petra,

exactly

perhaps:-

Well, the reason there's no reply is dead simple: comma's are valid in
urls. Dots are valid in urls, etc. There is no real simple way to do it.

Re: help with regex


I think your problem is you dont really know what regex is or is for
this is not a regex problem but a programming one.

Well, the OP's problem...

Hardly. If it's unalterable data, and somehow url's have to be matched,
it's pretty much a regex job.

Now, if this was about new content added, it would be a
UI-related/scripting problem.
