Re: include text file

Here's a Java extension function I used while
formatting examples for my book (that I kept
in separate files so I could work on them, 
compile them, and test them from within
my Java IDE). This function reads in an
external text file and returns a single 
String representing its content.

I use it from within a stylesheet to read in
a filename like this:

   <xsl:value-of select="ext:contents(@fileref)"/>

where the "fileref" attribute is an attribute
in my source that holds the filename of the
external text file.

import java.io.*;

public class TextUtils {

  public static  String contents(String actualFileName) {

   FileReader in = null;
   try {
     in = new FileReader(actualFileName);
   }
   catch (FileNotFoundException e) {
     return "File '"+actualFileName+"' not found.\n";
   }
   StringWriter out = new StringWriter();

   char[] buffer = new char[4096];
   int numchars;
   try {
     while((numchars = in.read(buffer)) != -1)
            out.write(buffer, 0, numchars);
          out.close();
   }
   catch (IOException e) {
     return "IO Error reading file '"+actualFileName+"'.\n";
   }
   String returnContents = out.toString();
   return returnContents.trim();

  }

}

| Yes, post it, if it's that short.
