Best Way To "clean" An Innerhtml Scraped Attribute ?

[DjProg 3]

Hello guys,

 

What is the best way to "clean" an innerHTML scraped attribute ?

 

Basically I'm scraping an innerHTML containing an empty div "inline styled", for which I need to find the inline styled background-image URL... 

 

<div class="blablah" style="height:120px;background-image:url(http://somewhere.com/image.jpeg)"></div>

 

I scraped the innerHTML of the parent div of blahblah because else I didn't get what I needed, but now I need to clean up a bit.

 

Any tip is welcome !

 

Thanks a lot,

 

Cheers,

Regex is the answer for this, here is an example:

set(#html,"<div class=\"blablah\" style=\"height:120px;background-image:url(http://somewhere.com/image.jpeg)\"></div>","Global")
set(#image_url,$find regular expression(#html,"(?<=image\\:url\\().*?(?=\\))"),"Global")

Thanks !

 

I forgot to say but I'm adding the scraped attributes to a List.

 

So after adding to list I would need to loop thought my list to "replace" the dirty innerHTML into the "cleaned", regexed text ? Or it there a more elegant solution ?

Here are two examples of how you can add it to a list either one at a time like this:

clear list(%image_urls)
set(#html,"<div class=\"blablah\" style=\"height:120px;background-image:url(http://somewhere.com/image.jpeg)\"></div>","Global")
add item to list(%image_urls,$find regular expression(#html,"(?<=image\\:url\\().*?(?=\\))"),"Don\'t Delete","Global")

Or if you need to add more than one at a time:

clear list(%image_urls)
set(#html,"<div class=\"blablah\" style=\"height:120px;background-image:url(http://somewhere.com/image1.jpeg)\"></div>
<div class=\"blablah\" style=\"height:120px;background-image:url(http://somewhere.com/image.2jpeg)\"></div>
<div class=\"blablah\" style=\"height:120px;background-image:url(http://somewhere.com/image.3jpeg)\"></div>
<div class=\"blablah\" style=\"height:120px;background-image:url(http://somewhere.com/image.4jpeg)\"></div>","Global")
add list to list(%image_urls,$list from text($find regular expression(#html,"(?<=image\\:url\\().*?(?=\\))"),$new line),"Delete","Global")
