Filter (search and replace) array of bytes in an InputStream

Question

I have an InputStream which takes the html file as input parameter. I have to get the bytes from the input stream .

I have a string: \"XYZ\". I\'d like

Answer 1

There isn't any built-in functionality for search-and-replace on byte streams (InputStream).

And, a method for completing this task efficiently and correctly is not immediately obvious. I have implemented the Boyer-Moore algorithm for streams, and it works well, but it took some time. Without an algorithm like this, you have to resort to a brute-force approach where you look for the pattern starting at every position in the stream, which can be slow.

Even if you decode the HTML as text, using a regular expression to match patterns might be a bad idea, since HTML is not a "regular" language.

So, even though you've run into some difficulties, I suggest you pursue your original approach of parsing the HTML as a document. While you are having trouble with the character encoding, it will probably be easier, in the long run, to fix the right solution than it will be to jury-rig the wrong solution.
