Using for() to find characters in text.
Feb 6th, 2010, 6:51am  
Hello, i have a source of links that i want to use in Processing, but at the moment, for some reason the links from the source have been escaped with '\''s  
e.g. instead of "ht tp://processing.org/", I get "ht tp:\/\/processing.org\/". (please excuse the spaces, I'm not allowed to post real links yet).

Can I use the looping from the for() with the charAt() or indexOf() functions to go through the links and remove the '\' symbols?
I've had a play around with this, and I know that each time it loops through the letters of the link i need to set a new start/end point to copy the text either side of the '\' mark, but i cant get it working. Is this the approach I should be using? Thanks!

What is your source?
If that's a text file, just open it in a good text editor and replace \ with nothing.
If the source is dynamic, you can do link = link.replaceAll("\\\\", "");

It would replace the "\\" pattern. You need two backslashes to select a backslash, because the backslash is the escape character...

You didn't spot it because it's not in the Processing Reference - but it is in the Java Reference.
