Example #1 Extract JSTE code from a mixed HTML document

<html><head>
<?php echo '<title>title</title>'; ?>
<#
alert('Hello World');
#>
</head>
<body>
<?php
// PHP code
echo 'hello world!';
?>
<%
response.write("Hello World!")
%>
<!-- Comments -->
Hello World
</body></html>
Outside HTML
HTML;
$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 -> isJste ()) {
echo "\n\n# jste 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 );
}
}
}
?>
以上例程会输出:
# jste node #1 <# alert('Hello World'); #>
