I am writting a class that will help me to cope with the ammount of XML feeds in my niche. I need a function that might get called in theory as many as 1000 times but might be called an average of 40 times (per page request).
As such I am looking for efficiency.
The function will take the following inputs: text (HTML formatted), length (in characters).
It should output text without HTML that is length characters long but it should not break in the middle of a word. Also the text should have added to the end three full stops like this..
This output should also be XML safe without using cdata so things like £ & and friends need to remain (HTML encoded/escaped).
Hopefully this makes sense.
Help, tips or an outright solution appriciated. I'll assume anyone is free to use any code given in anyway desired unless you say otherwise.
