How can I replace strings NOT within a link tag?

Hi is there anyone can help me with regular expression

This is the words that i want to replace 

$text = '<a href="test-pregnancy.net">pregnancy<a> week by week, some time pregnancy can be very easy';
$search = 'pregnancy';
$replace = '<a href="google-pregnancy.net">pregnancy</a>';

print preg_replace('/('.$search.')/', $replace, $text);

is there any regular expression that except for words that contain inside a link? only replace words that not contain inside a link

I want it would be like this 

$text = '<a href="test-pregnancy.net">pregnancy</a> week by week, some time <a href="test-pregnancy.net">pregnancy</a> can be very easy';

How if the condition like this.

$text = '<a href="test-pregnancy.net" title="welcome pregnancy people">pregnancy<a> week by week, some time pregnancy can be very easy';

This will also replace pregnancy in the title of href. Is there any another idea. I want a regex that using exception inside a tag.

    That is some really weird sample text. – BoltClock Jan 06 '12 at 01:16

    No, there is no regular expression that can do that. At least not if your HTML is much more complex than one anchor followed by some text. – Paul Jan 06 '12 at 01:17
  • Yes, that's doable. Came up before, use the search function. – mario Jan 06 '12 at 01:18

    @BoltClock why? because "pregnancy" is spelled correctly, but "verry" isn't? :^P – Maarten Bodewes Jan 06 '12 at 01:20

    @BoltClock while you are busy, maybe we should replace the rather woman-unfriendly sample text and change "exeption" in the title to "exception" - personally, I think this post amounts to trolling though, and I don't think this question has not been answered before – Maarten Bodewes Jan 06 '12 at 01:34

replace:

$search =  'pregnancy';

with:

$search =  ' pregnancy ';

You should use a HTML parser and find the text that is not part of an A element. See: http://simplehtmldom.sourceforge.net/
