Answer 1

您可以使用setAttribute

public DOMAttr DOMElement::setAttribute ( string $name , string $value )

Answer 2

您只需使用 PHP: XMLWriter 即可： http://php.net/manual/de/function.xmlwriter-write-element.php

也用于阅读 XML-文件： http://php.net/manual/en/simplexml.examples-basic.php

它是远程 XML 还是本地网络服务器？ - 问题是你不能即时编辑远程文件，我想。最好的方法是获取旧的，在解析 XML 时更改值并再次保存。
