When it would be: == function xpath(DomDocument $arg) {

    return new DomXPath($this->loadXML($arg));

} ==

function xpathFromDom($arg) { return new DomXPath($arg); } function xpathFromTree($arg) { return new DomXPath($this->loadXML($arg->getSource()))); } function xpathFromString($arg) { return new DomXPath($this->loadXML($arg)); } Works perfectly well. And you don't even need to document them because the names speak for themselves. A much simpler (and clearer) solution IMHO. If you want an OO way I'd prefer something like $xpath = $obj->getXPath(); to $xpath = $this->xpath($obj); anyway. This doesn't work with basic types like strings but having a special case there is not a problem IMHO as using those two interchangeably will lead to other problems anyway. - Chris
