Eregi - I don't get it!

[Anon]

Hi there folks.

I'm trying write something that reads through a HTML document and picks out certain bits of it to display. I've almost got it, but I just don't get eregi and what I need to do to it to get it to work.

This is what I have (curtesy of someone else):

<?
$url = "http://localhost/test.htm";
$file = file($url);
while ( list( , $line ) = each( $file ) ) {
while ( eregi( '(href[[:space:]]=[[:space:]]"?[[:alnum:]:@/._-]+"?)(.*)', $line, $links ) ) {
echo "$links[1]<br>\n";
$line = $links[2];
}
}
?>

This goes through and pulls out all the links and works like a charm, but how do I make it so that it gets the info outside the tag?

Basically, this is what I want:

HTML FILE:
<a href="http://somelink.com">This is the link</a>
<a href="http://someotherlink.com">This is another link</a>

PHP OUT PUT:
This is the link
This is another link

Whereas currently I get:
href="http://somelink.com"
href="http://someotherlink.com"

Can someone please explain what I need to do (in Laymen's terms....I'm a bit stoppid!)

Thanks heaps

Brad

Hello,
Select everything from this area of your tags when you run the page through your eregi parsing (selected region indicated within brackets):

<a href="[http://www.domain.com">Some text]</a>

This will give you:
http://www.domain.com">Some text

Then, you can separate these two elements using explode:

$links[$i] = explode("\">", $links[$i]);

This should give you an array of links where the [0] key holds the url and the [1] key holds the text that belongs to it.

i.e.

foreach ($links AS $link) {
echo "url: " . $link[0] . " -- txt: " . $link[1] . "<br>";
} //end foreach

This also limits the amount of regexp processing you do, which is always important to consider. You should consider being more strict with your regexp matching and not check for whitespace before and after the = character (it shouldn't be there anyway). If you need to check for it, use [ ], which will only look for a space character and not tabs, line breaks, etc. as the [[:space:]] pattern does. Just conjecture...
