tidyNode::isText — Checks if a node represents text (no markup)
Tells if the node represents a text (without any markup).
Returns TRUE if the node represent a text, FALSE otherwise.
Beispiel #1 Extract text 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 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->isText()) {
echo "\n\n# text 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);
}
}
}
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
# text node #1 Hello World # text node #2 Outside HTML
