Get content of div with id

Problem using DOM

[kiwibrit]

I need to get the content of a div with id on a web page.

The code below grabs all the content (showing include call ups, not the include content). Outside the required div the code shows no line returns - inside it does show the line returns, so in that sense it does highlight the required div. The id div does have class divs nested within it - these show up correctly. How can I stop the unwanted coding outside the required div being written to the text file?

$dom = new DOMDocument();
libxml_use_internal_errors(true); 
@$dom->loadHTMLFile("$url"); 
libxml_use_internal_errors(false); 
$xpath = new DOMXpath($dom); 
$divTag = $xpath->evaluate("//div[@id=intwrap]"); 
$divcontent = $divTag->item(0);
$content = $dom->saveXML($divcontent);
$content = str_replace("
", "\r", $content);
$file = 'test.txt';
file_put_contents ($file, $content);
header('Location: test.txt');

This does give me just the text content of the div - but no tags or line breaks, which I need. Could this be developed to what I want? Right now I can't figure it.

$dom = new DOMDocument;
libxml_use_internal_errors(true);
$dom->loadHTMLFile("$url");
libxml_use_internal_errors(false);
$node = $dom->getElementById('intwrap');
echo $node->nodeValue;

Thanks to some helpful posts on phpBuilder, this one has been cracked. For the sake of anybody who looks here for assistance, this does what I want.

$dom = new DOMDocument;
libxml_use_internal_errors(true); 
$dom->loadHTMLFile("$url");
libxml_use_internal_errors(false);
$node = $dom->getElementById('intwrap');
$content = $dom->saveXML($node);
$content = str_replace("
", "", $content);
$file = 'test.txt';
file_put_contents ($file, $content);
header('Location: test.txt');

Note: I am using php 5.3.5
