I'm experiencing a slight problem with importNODE putting unwanted
carriage returns in the the output.
Here's my function:
// syntax highlighting
include_once('Text/Highlighter.php');
function syntaxHighlight($dom,$lang,$code) {
$hl =& Text_Highlighter::factory($lang);
$out = $hl->highlight($code);
//die($out);
$tmpDOM = new DOMDocument('1.0','UTF-8');
$tmpDOM->loadXML($out);
$foo = $tmpDOM->saveXML();
//die($foo);
$nodeList = $tmpDOM->getElementsByTagName('div');
$impDIV = $nodeList->item(0);
$returnDIV = $dom->importNode($impDIV,true);
return $returnDIV;
}

Here's my test:
$code ="<?php" . "\n\n";
$code .="require_once('/path/to/something');" . "\n";
$code .="function somefunc(\$myfoo,\$mybar) {" . "\n";
$code .=" \$myfoobar = \$myfoo . \$mybar;" . "\n";
$code .=" return \$myfoobar;" . "\n";
$code .=" }" . "\n";
$code .="?>" . "\n";
$fooTest = syntaxHighlight($dom,'PHP',$code);

If I uncomment the die($out) - I get what I expect spit to the screen,
view source shows code that will do what I want.
If instead I uncomment die($foo) - I also get what I expect spit to
screen. view source shows code that will do what I want.
However, if the function is allowed to continue, the imported div has
carriage returns between each and every </span><span> which of course
completely breaks the browser display because they are inside a
<pre></pre> node.
Anyone know why importNode does this and how to fix it?
The only (untried) solution I can think of is to replace each carriage
return with a <br /> and every space with   and then replace the
<pre> with a <div class='monospace'> or some such hackery before running
loadXML() on it. But I would rather not do that.
