Syntax highlighting

I have a webpage that contains an iframe. I'm opening text files into that frame and I want to highlight java code in the text. I've googled syntax highlighters and came across geshi. Thing is I dont know much about php so I'm a bit confused as to how to use it even with the instructions for basic use.

Here's the how to bit about the highlighter.

//
// Include the GeSHi library
//
include_once 'geshi.php';
 
//
// Define some source to highlight, a language to use
// and the path to the language files
//
 
$source = '$foo = 45;
for ( $i = 1; $i < $foo; $i++ )
{
  echo "$foo\n";
  --$foo;
}';
$language = 'php';
 
//
// Create a GeSHi object
//
 
$geshi = new GeSHi($source, $language);
 
//
// And echo the result!
//
echo $geshi->parse_code();

Can anyone explain how I use that in relation to the following bit of HTML ?

<a href="page1.txt" target="iframe" onClick="showFrame()">Link to page 1</a>

Haven't used the library before, but at a guess you could hack your two sections together like this:
[PHP]
//
// Include the GeSHi library
//
include_once 'geshi.php';

//
// Define some source to highlight, a language to use
// and the path to the language files
//

// Assign your source instead of the sample given. Potentially you want to put a segment to read file contents into the $source variable as a string though, and then pass that to geshi
$source = '<a href="page1.txt" target="iframe" onClick="showFrame()">Link to page 1</a>';

$language = 'html'; //Assuming this is a valid option :-)

//
// Create a GeSHi object
//

$geshi = new GeSHi($source, $language);

//
// And echo the result!
//
echo $geshi->parse_code();[/PHP]

I think you misunderstood me. I dont want to apply it to that line of html I want to apply it to the txt file that I'm sending into the frame with that line of html.

So could I give it the file as a source and then direct the echo to the frame ? Or open a php file in the frame with that code using the file as a source ?

Ah, I get you now, apologies for the mix up! I think half of your post just went straight out of my head as I read it

Anyway, since you're going the route of an iframe, I would suggest potentially having a php script that can read a file whose name is passed, and simply echo that it out that as an appropriately highlighted string. You can then use this as the source/content of the iframe, and trigger changes in that as required, if you get me? Of course make sure that the file handling doesn't expose anything that it shouldn't too
