eregi_replace and link conversion

ucbones

Hi,

In my previous thread, I asked for a way to convert all instances of things like:

<a href="http://www.boo.com/dir/boo.php">link text</a>

to:

http://www.boo.com/dir/boo.php

the solution I came up with was:

function htmltotext($html){
$text=stri_replace("<br>","\n",$html);
$text=str_replace(" »","",$text);
$text=eregi_replace ("<a[^>]+href *=\" *([^ ]+)[^>]*\">([^ ]+)</a>", "\\1", $text);
return strip_tags($text);
}

Unfortunately, it only converts the first instance of a link correctly, all else are returned wrongly. I thought maybe preg_replace would work better, but preg_replace doesn't work at all with that regexp.

Many thanks in advance,

ucbones

NB. stri_replace is a function I've defined in my functions file, and does not exist as a built in function, see the manual for various ideas of how to define it!

Try this ...

preg.html looks like:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Hello world</title>
</head>

<body>
<h1>Hello world</h1>
<a href="www.google.com">Google</a>
<h2>Goodbye world</h2>
<a href="www.bbc.co.uk">BBC</a>
</body>
</html>

The php looks like:

$file_string = join("", file("preg.html"));
echo(htmlspecialchars($file_string));

$search = '/<a +href="([^{"]+)">(.)+<\/a>/';}
$replace = '\1';
$file_string = preg_replace ('/<a +href="([^{"]+)">(.)+<\/a>/',} '\1', $file_string);

echo(htmlspecialchars($file_string));

Note:
1) I haven't put used the bb-php tags in this message because it causes problems with escape-characters.
2) I've used single-quotes to de-limit the search and replace strings so as not to get confused with the double-quotes used for HTML attribute values.
3) This only works for links with href only.
4) I've only used htmlspecialchars() so you can view the result in the browser.
