Getting relative urls from html code

[ohitsme]

Hi,

 

I grab the contents of a page of galleries (eg, http://www.example.com/galleries/gallery.htm).  Then i want to grab the images on it. Normally this is ok, as I assume the images are in the same directory as the html file, so i just do file_get_contents(str_replace("gallery.htm","",$url) . "1.jpg")

 

But sometimes the images are like

<img src="../otherdirectory/1.jpg">

or

<img src="http://static.example.com/gals/1.jpg">

 

How can i work out what is the correct url to retrieve?

 

(at the moment i have an array of the contents of all src="" (eg,

1 => 1.jpg

2 => 2.jpg

 

or

1 => http://static.example.com/1.jpg

2 => http://static.example.com/2.jpg

 

or

1 => ../otherdir/1.jpg

2 => ../otherdir/2.jpg

 

(this isn't for any illegal scraping or whatever. It just saves me a manual task i have to do every day)

 

thanks

I´m wondering the same thing.

Is there a way to grab both the thumbnail AND the original image?

Maybe some code that can scrape 2 level depth, or following links somehow?
