The function extract from the class is: private function widgeter($doc) { //Give it an DomDocument HTML containing <widget>

问题 I'm adding a #b hash to each link via the DOMDocument class. $dom = new DOMDocument(); $dom->loadHTML($output); $a_tags = $dom->getElementsByTagName('a'); foreach($a_tags as $a) { $value = $a->getAttribute('href'); $a->setAttribute('href', $value . '#b'); } return $dom->saveHTML(); That works fine, however the returned output includes a DOCTYPE declaration and a <head> and <body> tag. Any idea why that happens or how I can prevent that? 回答1: That's what DOMDocument::saveHTML() generally does,

How to “refresh” DOMDocument instances of LibXML2?

由 风格不统一 提交于 2019-12-23 05:29:20
问题 Using PHP to illustrate: there are a BUG in the normalizeDocument() method, or a lack of a "refresh" method, because DOM consistence is lost after changes (even only attribute changes)...
