解析网页没有破碎的字符串

I'm trying to parse some strings from a web page but I keep getting strings that happen to be broken up with no way to check if the string is complete or not. At the moment, I have a buffer of 1024 bytes that I'm receiving parts of the page with. What should I do to make sure I get the full string, preferably without an overly large buffer.I'm trying to parse some strings from a web pag
