counting words with domDocument class

How can i counting the words in a html page, with domDocument?

for example, if the input is something like:

    <div> Hello something open. <a href="open.php"&g开发者_JS百科t;click</a> 
    lorem ipsum <a href="open.php">here></a>

the output:

Number Word

1 Hello

2 something

3 open

4 click

5 lorem

6 ipsum

7 here.

And what if i need only the linktext?

click 4

here 7

If you need this for the entire document, it is likely easier to just strip_tags and then run str_word_count on the result.

If you have to do this with DOM, you can do

$str = <<< HTML
<div> Hello something open. <a href="open.php">click</a>
lorem ipsum <a href="open.php">here></a></div>
HTML;

$dom = new DOMDocument;
$dom->loadHTML($str);

$xpath = new DOMXPath($dom);
$nodes = $xpath->query('//text()');

$textNodeContent = '';
foreach($nodes as $node) {
    $textNodeContent .= " $node->nodeValue";
}
print_r(str_word_count( $textNodeContent, 1 ));

Using text() as the XPath expression will only give you the textnodes in the document. You can limit this to just return the link texts with //a/text() for the expression.
