问题
I've have the following (PHP) code that traverses an entire DOM document to get all of the text nodes. It's a bit of a ugly solution, and I'm sure there must be a better way... so, is there?
$skip = false;
$node = $document;
$nodes = array();
while ($node) {
if ($node->nodeType == 3) {
$nodes[] = $node;
}
if (!$skip && $node->firstChild) {
$node = $node->firstChild;
} elseif ($node->nextSibling) {
$node = $node->nextSibling;
$skip = false;
} else {
$node = $node->parentNode;
$skip = true;
}
}
Thanks.

The XPath expression you need is //text()
. Try using it with DOMXPath::query. For example:
$xpath = new DOMXPath($doc);
$textnodes = $xpath->query('//text()');
