PHP: simplexml_load_string-Manual- http://www.php.net/manual/zh/.

you can save xml in mysql as a string. When you use it, you can use ExtractValue (), a method specifically dealing with xml provided by mysql, to extract the contents of xml, or you can use UpdateXML () to update xml,. You can consult official documents
