Question

is there a way to validate that inside html tags there is an ul with several li objects (I am using groovy). I need that in order to check that the html generated its valid in an unit test.

I would like to :

• Extract the number of li elements with its data
• Validate that the is inside an specified with an specified class, inside that div could be different html tags but i don´t care about them

Example text:
<div class="example">...<ul><li>Element1</li><li>Element2</li><ul>...</div>

I have tried the most simplest way: <li>.+?</li> , with this I am able to extract the li elements, but I need to check the valid ul div structure.

why this is not working ? <div class='example'>.+?<ul>(<li>.+?</li>)*<ul>.+?</div>
How should it be ?

Any tips?

Thanks a lot

Using an HTML scraping library such as jsoup is easier and fun than using plain regex. Since jsoup is a java library, you should be able to use it with groovy.
