Regular Expression

Anon

Hi,

I would like to have a regular expression which replaces substrings like "Hi, all fine here" to "Hi, all fine here". So all strings contained in xx should be replaced with xx. This is no problem but the expression should not replace items contained for example in html-tags !
My current expression (ereg_replace("([]+)_","\1",$text)) doesn't take care of that and so also replace strings like "<a href="aa.ad/image/454_45.jpg>dfhf</a>".
Could anyone help me ?

Thanks a lot,
Corin

<?
$text = '<a href="blah">link</a>';
echo ereg_replace("+(.[]+)_+","<ul>\1</ul>",$text);
?>

hmmm... that looked like crap.
Damn forum.

Let's try this again...
<?
$text = '<a href="blah">link</a>';
echo ereg_replace("+(.[]+)_+",">ul<\1>/ul<",$text);
?>

Hi,

Thanks for the fast reply, but this also doens't work. Try the following:

<a href="http://data.abc.de/der-hut/galerie/fotoalbum_3377.jpg" target="_blank">http://data.abc.de/der-hut/galerie/fotoalbum_3377.jpg</a>
gets:

<a href="http://data.abc.de/der-hut/galerie/fotoalbum3377.jpg" target="blank">http://data.abc.de/der-hut/galerie/fotoalbum_3377.jpg</a>

which is wrong... :-((

Well Corin...
Look at this:
3377.jpg" target="

No wonder.

You'll need to think up some better rules to go by for your regex.

This is a quick fix for your one problem, but I'm sure there'll be many more.

<?
$text = '<a href="http://data.abc.de/der-hut/galerie/fotoalbum_3377.jpg" target="blank">http://data.abc.de/der-hut/galerie/fotoalbum_3377.jpg</a>';
echo ereg_replace("+(.[^{\"]+)+","<ul>\1</ul>",$text);}
?>

Yes I know, but how do it setup a rule like don't replace all _ when we are inside a < and " char ? This would prevent all links to be altered because all links start with < xxx "xxx and end with xxx" xxx >.
May be it would be sufficient to simply detec if we are inside two " chars ? Could you please help me.. :-)
