File compare incl wildcards for variables with Robot Framework
There is no way to cause that keyword to ignore parts of the HTML. You will  have to write your own keyword, or modify the html before doing the compare.
Im trying to compare the page source with Robot Framework. I added the robotframework-difflibrary for extra compare, however I can not send a wildcard for check. 
In my page source there is always the date and time which will never be the same. So my result will always be false because the date / time part is different.
Is it possible to let Robot Framework to ignore some parts of the HTML?
Example of time / date HTML tag:
td class="r">12:43:01
td class="r" width="10%">8-8-2017
