preg replace - replace links

[pairbrother]

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>.

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

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

with

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

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

<?php

$replacement = preg_quote('toreplace','|'); // Replace 'toreplace' with your string.
$source = '<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>.';

$newtext = preg_replace('|(<a href=\")' . $replacement . '(/.*?)(?=\")|i','$1$2.html',$source);

?>

 

Birds do it.  Bees do it.  That should do it.

nope

didnt worked, gave me the same string as the source.

anyways...i got it using this:

 

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

 

Thanks for the reply though.

Oh, you had your double quotes escaped in your example, so I included them in my solution, which is why it didn't work.  But yours works, so no worries.
