Yep.

In my experience, until you've made the mistakes that not properly parsing html leads to - you mostly jump to naive regex/substring solutions too quickly where you should learn/use well tested html parsing libraries instead. Those mo4re advanced techniques aren't always required, but they're worth knowing and once you know them it's smarter to "over solve" the problem sometimes than "cowboy it" with a regex just because it looks like it'll do the job.
