Hi,

Say I want scan a source code of a website.

Often a website refer to another website.

Usually, they contain things like:

src="someotherpage.htm"

I want to delete all such src="whatever" from the site.

How do I do that?

Will this work?

I got a code that work to change all <form whatever> to </form>

$content = preg_replace("'<form[^>]*?>'si",'<form>',$content);   

The thing is, " is a special character.

Will this work?

    $content = preg_replace("'src=\"[^\"]*?\"'si",'',$content);

try: $content = preg_replace('/src="[^"].*"/', '', $content);

Note that HTML element attribute values can be quoted by either ' (single quote) or " (double quote) characters, so you really need to check for both. Also, though it is invalid HTML, some web authors omit the quotes around the value and most browsers will still process it correctly (as long as there are no spaces in the value).

$content = preg_replace('/src=([^\s>]*|[\'"][^\'"]*[\'"])/i', '', $content);
