Need help with regular expression for relative addresses

[dimitad]

Hi all,

I have searched for this a lot but with no success. There is a module called LinkExtor which automatically extracts links contained in a web page within tags like "a href" and "src". However, this is not complete since links can be present in other places on a webpage (e.g. javascript) so now i am looking for a module or regular expression that would match any links on a page regardless of their location.

Thanks!

I'm sorry, I'm not sure I know what you mean by this ?

Ok,

Lets say you have a link on your page called "something.php". The currently available modules will try to locate this link with regular expressions that match tags like: <a href, <img src=, <form action=, and so on. So, if the link "something.php" is contained within one of those tags it will be processed. However, you might have javascript that says:
window.open = ("something.php" ...
or
location.href = ("something.php"

Those along with other cases do not get matched so I was looking for a regular expression that would match all extensions (.php, .asp, .html, .php3, .php4, .pl etc) within a web page assuming you have access to the actual file and not just the static page source.

Your script could call Javascript code, assign the output to a variable, and then parse the variable for the links you seek

Hmmm,
sorry but does Javascript have better support for parsing links from a given file?

You could write your own ;-)
