Selecting An Element According To What It Is Not

[yonatankra 1]

Hi,

One of my "target" websites marks certain elements using some attribute.

For instance:

<a href="blahblah" myMarkingAttr="1">Don't click me</a>

While other links would be:

<a href="blahblah">I'm the one you want to click</a>

I want to create a list of all the <a> elements that are missing the "myMarkingAttr" attribute.

Any way to do this?

First get the links that don't contain that text on to a list like this:

clear list(%no_myattr)
clear list(%links)
add list to list(%links, $scrape attribute(<tagname="a">, "outerhtml"), "Delete", "Global")
loop($list total(%links)) {
    set(#next_link, $next list item(%links), "Global")
    if($contains(#next_link, "myMarkingAttr")) {
        then {
        }
        else {
            add item to list(%no_myattr, #next_link, "Delete", "Global")
        }
    }
}

Then when you go to get the url it will have to be extracted like this:

set(#url, $find regular expression($next list item(%no_myattr), "(?<=href=\\\").*?(?=\\\")"), "Global")

Regular Expression is your friend , I know  it's tedious and kinda scares people off

But I highly suggest you sit down for an hour or two and take the time to understand it!

 

Regex is needed a lot in ubot and having that knowledge at your disposal is always great
