Modifying a text file question.
Oct 17th, 2006, 3:23pm  
Hi. I want to be able to take a certain text file, which is basically a list of names and then have a program that will take off a certain piece of information from each line. Basically each line is a name followed by information in parenthesis, and I want to get rid of the information in the parenthesis. Im kind of just starting in Processing and haven't tried anything with text or other documents like this before. If anyone knows of the best way to go about doing this it'd be a great help. Thanks.

I think that the code below should do what you need.

Code:
String[] data;
data=loadStrings("MyFile.txt");

for(int i=0;i<data.length;i++)
{
  int bracketPos=data[i].indexOf("("); 
    //finds the (

  data[i]=data[i].substring(0,bracketPos-1); 
    // replace a line with just the first part of the line
}
saveStrings("MyEditedFile.txt",data);
