Using PHP in XPath

/ Published in: PHP

I'm using this out of laziness.
PHP is slowing things down here, since it's not as close to C as XPath.
A better solution would be to have an attribute specifically for search purposes (either in upper or lowercase).

Expand | Embed | Plain Text

Copy this code and paste it in your HTML

$xpath = new DOMXPath($dom);
if (method_exists($xpath, "registerPHPFunctions")) {
    $xpath->registerNamespace("php", "http://php.net/xpath");
    $xpath->registerPHPFunctions('strtolower');
    $query = "/root/item[contains(@name_es,'$term') or contains(php:functionString('strtolower',@name_es),'$term')]";
} else {
    // fallback without PHP
}
