side effects "Enforce proper nesting of HTML"

I just noticed that my display of this node How to analyse structured data to get a hash was totally messed up (no line breaks), but becomes kind of "readable" after I logged off (the OP avoided code tags)

Like this but there are strikes thru the break tags

I have a file with rows of data which are typically like</br> Attr num
+="101" 
name="Created" desc="Time file was created." type="t" ord="3" value="2
+017-06-
03T11:27:23+01:00"</br> I want to analyse this so that I can get a has
+h with
 data like </br> Attr num ->101</br> Name ->Created</br> Desc ->Time f
+ile was
...

Turned out that my Display Settings had "Enforce proper nesting of HTML" enabled, which didn't go well with the OP's use of </br> tags.

Though after reading the help page, I don't understand why

Enforce proper nesting of HTML - If set, PerlMonks adds explicit closing tags in cases where an element was implicitly closed due to the ending of an outer element.

Merely an information, not sure if this demands action.

FWIW: disabled the option now.

Because many browsers have decided to treat `</br>` as if it were something useful like `<br />`. The current version of our HTML parsing code does not go quite so far in assigning meaning to nonsense. - tye	[reply] [d/l] [select]

I would support it. I would support removing deprecated HTML as well. *No matter how hysterical I get, my problems are not time sensitive. So, relax, have a cookie, and a very nice day!* Lady Aleena	[reply]
