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)
XMLReader::readInnerXML — Retrieve XML from current node
설명
public string XMLReader::readInnerXML
( void
)
Reads the contents of the current node, including child nodes and markup.
인수
이 함수는 인수가 없습니다.
반환값
Returns the contents of the current node as a string. Empty string on failure.
주의
Caution
이 함수는 PHP가 libxml 20620 이후와 함께 컴파일 되었을 때만 사용할 수 있습니다.
참고
- XMLReader::readString() - Reads the contents of the current node as a string
- XMLReader::readOuterXML() - Retrieve XML from current node, including itself
- XMLReader::expand() - Returns a copy of the current node as a DOM object
