If command to disable webparser measure upon empty return?

[bohregard]

So I'm using the webparser plugin to parse this page:

However the problem I run into is that when I add a file to this website, the xml populates another <slot>....</slot> field with all the stuff in between. That's not really a problem, the problem is really when the xml removes said field when the process is finished.

My question: Is there a way to adjust the code in rainmeter to disable the webparser measures that produce errors because the measure has matching errors (due to the field no longer being there)?

Here's the code I'm using for refrence:

Code: Select all

It's not really a big deal since the only thing that bugs me is the log page has tons of error messages constantly showing up. It just makes sorting through them a pain.

Thanks!

What might be better is to use Lookahead assertions so a given WebParser just returns an empty string when it fails, instead of sending an error to the log.

RegExp=(?siU)(?(?=<slot>(.*)</slot>.*<slot>(.*)</slot>)<slot>(.*)</slot>.*<slot>(.*)</slot>)

Ahhhh, ok I'll give that a go. Thanks!
