Example #1 Extract ASP code from a mixed HTML document
<?php$html = <<< HTML<html><head><?php echo '<title>title</title>'; ?><# /* JSTE code */ alert('Hello World'); #></head><body><?php // PHP code echo 'hello world!';?><% /* ASP code */ response.write("Hello World!")%><!-- Comments -->Hello World</body></html>Outside HTMLHTML;$tidy = tidy_parse_string($html);$num = 0;get_nodes($tidy->html());function get_nodes($node) { // check if the current node is of requested type if($node->isAsp()) { echo "\n\n# asp node #" . ++$GLOBALS['num'] . "\n"; echo $node->value; } // check if the current node has childrens if($node->hasChildren()) { foreach($node->child as $child) { get_nodes($child); } }}?>
