Just asking: why is this different than $crawler->filter('body > p.lorem'); Thanks!

Also, we'll need to add the following after this new content:

.. versionadded:: 4.2
    The ``children()`` method was introduced in Symfony 4.2.

@javiereguiluz It's not different than $crawler->filter('body > p.lorem');, it's just that it was not possible before to get the same result directly from the body node.

You can see more details about the problem that was solved, here.


.. note::

All the traversal methods return a new :class:`Symfony\\Component\\DomCrawler\\Crawler`
