preg_replace help

[dico]

Hello,

I have the following string:

$string=" <tag> <hello>
<bye> <dog>

<cat>

<pig>
";

I need to replace all the white characters outside of the < and > so that it ends up like this:

$string="<tag><hello><bye><dog><cat><pig>";

Any help?

Thanks,

Perhaps something along these lines?

$string=" <tag> <hello>
<bye> <dog>

<cat>

<pig>
";

function stripSpaces($a){
	return preg_replace('#\s+#', '', $a[0]);
}

$string = preg_replace_callback('#(^|>)[^<]+<#', 'stripSpaces', $string);
echo $string;

Thanks! Works like a charm!
