Disregard my other comment.
readInnerXml does not advance the cursor, so you can call it more than once. I made a mistake testing this.
XMLReader::readInnerXml
(PHP 5 >= 5.2.0, PHP 7, PHP 8)
XMLReader::readInnerXml — Retrieve XML from current node

Reads the contents of the current node, including child nodes and markup.
参数
此函数没有参数。
