preg replace - replace links

Hi there,

I have a a large number of pages in which I want to replace parts of links within it. Ill give an example
This is the html I am getting from a function:

<p>In most <a href=\"/toreplace/Bird\" title=\"Bird\">birds</a> and <a href=\"/toreplace/Reptile\" title=\"Reptile\">reptiles</a>, an <b>egg</b> is the <a href=\"/toreplace/Zygote\" title=\"Zygote\">zygote</a>, resulting from <a href=\"/toreplace/Fertilization\" title=\"Fertilization\">fertilization</a> of the <a href=\"/toreplace/Ovum\" title=\"Ovum\">ovum</a>. It nourishes and protects the <a href=\"/toreplace/Embryo\" title=\"Embryo\">embryo</a>.

Code (markup):

I want to replace all the links in it for ex:

<a href=\"/toreplace/Bird\" title=\"Bird\">birds</a> 

Code (markup):

with

<a href=\"/Bird.html\" title=\"Bird\">birds</a> 

Code (markup):

That is I want to remove the text "toreplace" and add a .html at the end of the link.

I hope this is possible using php regex and I am at the right place amongst the right people.
Any help would be appreciated. Thanks a lot

 

Here is a simple regex pattern. Not perfect but for your situation, this should be fine:
href="/toreplace/([^"]+)" ==> /$1.html

To do it through PHP:

preg_replace('~href="/toreplace/([^"]+)"~', '/$1.html', $html);

PHP:

 

Ammazing! Thanks krt
A little editing was required though

preg_replace('~href="/toreplace/([^"]+)"~', 'href="/$1.html"', $html);

Code (markup):

 

Great, and glad you got that sorted out (and reminding me yet again to be more careful with the code I write )
