Scrub tasks don't clean html tags

[kirylrb]

Hello everybody,
There is some simple cases below with all HTML sanitizing tasks I found in docs.
Please make me clear about why I can't getting rid of html tags.
Env: Ruby 2.5.1, Loofah 2.0.3, Rails 5.2

irb(main):032:0> Loofah.fragment('<p>Test</p><p>Te3st &#13;</p>').scrub!(:strip).to_s
=> "<p>Test</p><p>Te3st \r</p>"
irb(main):033:0> Loofah.fragment('<p>Test</p><p>Te3st &#13;</p>').scrub!(:prune).to_s
=> "<p>Test</p><p>Te3st \r</p>"
irb(main):034:0> Loofah.fragment('<p>Test</p><p>Te3st &#13;</p>').scrub!(:escape).to_s
=> "<p>Test</p><p>Te3st \r</p>"
irb(main):035:0> Loofah.fragment('<p>Test</p><p>Te3st &#13;</p>').scrub!(:whitewash).to_s
=> "<p>Test</p><p>Te3st \r</p>"

@kirylpl I believe you want to use to_text and not to_s. Please let me know if there's something we can do to clarify this behavior in the README or other documentation?

flavorjones I tried with to_text method but still have no expected result, unfortunately - mean 
 characters leaved in the result.
Could you show how to strip example like this? It might be be perfect addition to readme.

irb(main):009:0> Loofah.fragment('<p>Test</p><p>Te3st &#13;</p>').scrub!(:strip).to_text
=> "\nTest\n\nTe3st &#13;\n"
irb(main):010:0> Loofah.fragment('<p>Test</p><p>Te3st &#13;</p>').scrub!(:prune).to_text
=> "\nTest\n\nTe3st &#13;\n"
irb(main):011:0> Loofah.fragment('<p>Test</p><p>Te3st &#13;</p>').scrub!(:escape).to_text
=> "\nTest\n\nTe3st &#13;\n"
irb(main):012:0> Loofah.fragment('<p>Test</p><p>Te3st &#13;</p>').scrub!(:whitewash).to_text
=> "\nTest\n\nTe3st &#13;\n"

@kirylpl I'm confused, the output you pasted above has the HTML tags removed. I think you're asking about removing the string 
, which is an entity (not a tag). Can you help me understand what output, exactly, you're hoping to see?

[kirylrb]

@flavorjones Yes, I want to get rid of this 
 tag as well as from html tags, kinda combination of to_text and not to_s results expected:
=> "\nTest\n\nTe3st \r\n"
OR even better if I will have new line only for closing tags like </p> which situated near openin tags like <p> .
=> "Test\nTe3st \r"

[flavorjones]

Sounds like you might want to try writing your own scrubber for this behavior! The README has some examples on how you might approach this task.

@flavorjones Adding .gsub(/(
|\s)+/, "\n"), dealt it for me.
