I'm trying to create a preg_replace that would remove from a <a href> tag that would replace the target attribute regardless of what the value might be.
Any ideas?
$foo = '<a href="http://www.foo.com" target="_blank" >www.foo.com</a>';
$foo = preg_replace('/(<a.*?)[ ]?target="_blank "(.*?)/', '$1$2', $foo);
That should work.

That should work.
Actually, now that I think about it, what about a preg_replace that would
replace any attribute except for the href attribure?

preg_replace('/(<a href=).*?(.*?)> (.*?)/', '$1$2$3', $text); should do
it for you.

No, sorry.
This:
<?php
$text = "<a href=\"test.htm l\" target=\"_blank \">test</a>";
echo preg_replace('/(<a href=).*?(.*?)> (.*?)/', '$1$2$3', $text);
?>
produced this:
<a href="test.html " target="_blank" test></a>

Try something like this (untested):
$pattern='`<a\s +[^>]*(href=([\'\"]).*\\2)[^>]*>([^<]*)</a>`isU';
$string=preg_re place($pattern, "<a $1>$3</a>",$string);

This, along with every other solution thus far posted, relies on href
being the first attribute. Parsing HTML with regexes is extremely
painful and much better suited to an HTML Parser. Unfortunately, I've
never used an HTML Parser in PHP (AFAIK, one was not available until
about a year ago, which is actually kind of ironic).
See <URL:http://us3.php.net/tidy>. Good luck though, there doesn't
seem to be much documentation. There's a tutorial here:

Um... did you even look at the solution I posted?
`<a\s+[^>]*(href=([\'\"]).*\\2)[^>]*>([^<]*)</a>`isU'
^^^^^
It only requires that href is there, and it is not case-sensitive, AND
the link doesn't need to be completely on one line...

Not closely enough, apparently :-(.

There are still situations where your regex will break[1] (admittedly,
many of them are awfully contrived). I still maintain that regular
expressions are not very well suited for parsing HTML.
I have to admit though, as far as regexes for parsing HTML can go,
that's a pretty good one.

Hi,
I've used an excellent way to make target="_blank" links that still

I learned the trick from : http://www.sitepoint.com/article/1041
Basically, instead of typing :

How i made the same effect in xHTML like the - target="_blank" - Tag
in HTML 4.01?
I will use it with xHTML and CSS ... but the validator say's to me,

Thx for answers!

I want to redirect the user to a url outside of our website but I want it to
preserve our application's window by opening a new window. We have a
datagrid that has five hyperlink columns containing links to external sites.
The hyperlink columns have the target="_blank" attribute so they preserve
the existing window. This works OK except that the NavigateURL's are quite
long due to the size of the query string and this makes the page slow. ...

I have a js function that dynamically generates a block of html that
includes an anchor tag :
<a href="http://www.google.com" target="_blank" />
When the user clicks this link, the new IE6 browser window is full vertical

Starting iexplore.exe independently opens a full-size browser window.

Anyone can suggest how to use it but selectively not open all the links.
