Replace lxml with html.parser

I didn't notice that lxml required an external dependency. Rather than add it, I've just replaced it with the native html.parser, apparently it's slightly slower but shouldn't matter for this.

ah, it is was old code, should have used "html5lib" instead like below code.

Ok switched to html5lib instead.

I've also added some extra steps to try and preserve some of the text data.

It's not a great example because in this case the HREF tag and contents were the same, but it helps preserve data in cases where its not such as Click Here to go to my site. Original: Click Here to go to my site
