Iterate through string characters to remove blockquotes

Question

I have a string with url and I want to remove blockquotes and characters after from the string.

String looks like http://pics.v6.top.rbk.ru/v6_top_pics/resized/250xH/media/img/7/92/754435534528927.jpg\"><div>Какой-то div</div>

So i try to make a for-loop which iterates through every character appending the to new string and stops when it finds blockquotes

I try following code

var value = "http://pics.v6.top.rbk.ru/v6_top_pics/resized/250xH/media/img/7/92/754435534528927.jpg\"><div>Какой-то div</div>"
var result = String()
for char in value.characters {
  var i = false
  if char == "\"" {
    let temp: Character = "\""
    result.append(temp)
    i = true
  } else if i != true {
    result.append(char)
  }
}
print(result)

but it does not work

Also I try while, but it causes infinite loop

for char in value.characters {
  while char != "\"" {
    print("hello")
  }
}

How to do this correctly ?

Thanks in advance!

UPD - i dont need to remove only quotes. I need to remove them AND everything after them

If you want to remove all characters from the double quote until the end of the string, it is easier to get the index of the substring with rangeOfString()

let value = "http://pics.v6.top.rbk.ru/v6_top_pics/resized/250xH/media/img/7/92/754435534528927.jpg\"><div>Какой-то div</div>"
if let offsetOfFirstDoubleQuote = value.rangeOfString("\"") {
  let result = value.substringToIndex(offsetOfFirstDoubleQuote.startIndex)
  print(result)
}

or, more specific, if the separator is always ">

if let offsetOfDoubleQuoteGreaterThan = value.rangeOfString("\">") {
  let result = value.substringToIndex(offsetOfDoubleQuoteGreaterThan.startIndex)
  print(result)
}
