Incorrect parsing for children of children #24

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
The following functions will return all children in the DOM object. However, it 
looks like if there is text between the nested tags it sometimes misses a 
child. For example, <div>Hello<span>world</span></div> will miss the span data. 
Also, the ability to dump the DOM into a JSON obejct as provided below would be 
a nice feature.

function get_all_children($el) {
    $output = array();
    $row = array(
        'name' => $el->getTag(),
        'raw' => $el->getInnerText()
    );
    for ($i = 0; $i < $el->childCount(); $i++) {
        $row['children'] = get_all_children($el->getChild($i));
    }
    foreach($el->attributes as $attr => $value) {
        $row['attribs'] = array(
            $attr => $value
        );
    }
    array_push($output, $row);
    return $output;
}

function get_dom_array($html, $selector) {
    $output = array();
    foreach($html($selector) as $el) {
        $row = array(
            'name' => $el->getTag(),
            'raw' => $el->getInnerText()
        );
        for ($i = 0; $i < $el->childCount(); $i++) {
            $row['children'] = get_all_children($el->getChild($i));
        }
        foreach($el->attributes as $attr => $value) {
            $row['attribs'] = array(
                $attr => $value
            );
        }
        array_push($output, $row);
    }
    return $output;
}

$html = str_get_dom('<html><body><div>Hello World</div></body></html>');
$dom_array = get_dom_array($html, 'div');
echo json_encode($dom_array);

After re-reading Issue #23, this might possibly be related. Not 100% sure.

In your example code, what would be the expected output? I believe span should 
be missing as it's not in your input string?

My apologies... After more testing, all children are being handled correctly. 
The error came from some really messy HTML input. Thanks for the script!
