Cutting HTML strings without breaking HTML tags

Question

How to write a function that can cut a string with HTML tags to an N-length string without breaking HTML tags while doing it.

The returned string doesn\'t need to b

Answer 1

This might be overkill, but try looking up AWK, it can do this kind of things pretty easily since it's centered around processing text.

You can also write a custom parsing script like

string s = "Visit Croatia this summer."

result = ""

slice_limit = 9

i= 0

j = 0

in_tag = false

while i < slice_limit and j < s.size do

  if s[j] == "<" then in_tag = true

  if in_tag and s[i]==">" then in_tag = false

  if !in_tag then i++

  result += s[j]

end

... or something like that (haven't tested, but it gives you the idea).

EDIT: You will also have to add something to detect if the tag is closed or not (just add a flag like in_tag and mix it with some regular expression and it should work) Hope that helps

EDIT2: if you gave the language you want to use, that could be helpful. javascript?
