fix raw tag parsing to include multi-line html

[SampsonCrowley]

fixes raw tag parsing mentioned in #95

since this is an HTML based library, and raw tags are supported in the repo, only allowing single line parsing is a huge surprise. this fixes that surprise

Cool. Last thing: wouldn't it be best (and simpler) to put those tests as new cases? I imagine that the output from the gem and the original js package were different for these and they simply should match.

@marcandre I'm not sure I follow, can you explain what you mean? As far as I remember (sorry not at my machine rn) I just added additional tests in the existing section that is testing this feature, to cover the expanded capability

The cases_spec checks all examples in cases/ and compares the output of the gem with the original tool. For the the <raw> specs, we can either do like you did in this PR and check the actual output or, instead, do what I'm suggesting and compare with the output of the original tool. The later avoids a situation where the original tool doesn't allow multiline <raw> tags, for example but the gem does. The ultimate goal of the gem is to reproduce the behavior of the original tool.

FWIW, I think the specs you edited predate the cases/

[SampsonCrowley]

Sounds like I need to rebase and edit a lil bit

[SampsonCrowley]

@marcandre so the main repo (I'm assuming at least) is also only parsing raw tags line-by line. does that mean I need to fix it there before proper multi-line HTML parsing will be allowed here for raw tags?

also after rebasing, it looks like the original <raw> tag testing never made it to the cases spec either FWIW

[SampsonCrowley]

I will be fixing the multi-line issue in the main repo, so this fix can be properly moved to the cases spec without failing tests
