Question

In my XML files, there are unicode line breaks like shown in this screenshot.

The two dots after “minds.” is the line break. I’ve googled and tried almost everything I know to replace them with ruby (1.8) but without any luck.

Here’s my code (with different tries of unicodes), maybe someone could help me.

def formatedBody
  t = self.body.gsub("\u000a","<br/>")
  t = t.gsub("\u000d","<br/>")
  t = t.gsub("\u0009","<br/>")
  t = t.gsub("\u000c","<br/>")
  t = t.gsub("\u0085","<br/>")
  t = t.gsub("\u2028","<br/>")
  t = t.gsub("\u2029","<br/>")
  t = t.gsub(/0A\0A/u,"<br/>")
  return t
end

The two 0x0A values are the hex representation of line-feeds. Regular ol’ ASCII line feeds, AKA "\n\n" in a string.

So, t = t.gsub(/\n/, "<br/>") should work.

t = "foo\u000d\u0009\u000c\u0085\u2028\u2029\nbar"
p t

t = t.gsub(/\u000d|\u0009|\u000c|\u0085|\u2028|\u2029|\n/,"<br/>")
puts t

You can replace the list of OR’d characters with:

t = t.gsub(/[\u000d\u0009\u000c\u0085\u2028\u2029\n]/,"<br/>")

Either way, the output would look like:

"foo\r\t\f\u2028\u2029\nbar"
foo<br/><br/><br/><br/><br/><br/><br/>bar

The reason your

t = t.gsub(/0A\0A/u,"<br/>")

doesn’t work is the regex is not correct.

t = t.gsub(/\x0A/,"<br/>")

is an alternate way of defining:

t = t.gsub(/\n/,"<br/>")
