아직 말할 수 없다면 Zillow API의 표준 출력입니다. 내가 배운 특정 태그 사이에 저장된 정보의 데이터를 저장하고 싶습니다.

예를 들어/searchResults : SearchResults/Request/Address의 데이터에 대해 어떻게 쿼리합니까? 변수를 반향/인쇄 할 때 이런 일을하는 것은 작동하지 않습니다.

$xml = simplexml_load_file("-truncated XML URL-");
$result = $xml->xpath('/SearchResults:searchresults/request/address')

내가 이해 한 바에 따르면, $ 결과 변수에는 해당 %값에 중첩 된 값이 % %, 맞습니까? 그러나 "배열"을 인쇄하고 print_r을 때리면 비워집니다.

Answer 1

다음은 해당 정보를 얻는 간단한 방법입니다.

<?php
    $xml = simplexml_load_file("test.xml");
    echo $xml->request->address;
?>

Answer 2

짧은 이름이 아닌 풀 네임 스페이스를 사용해야합니다.

Answer 3

사용 http://simplepie.org

$xml = "yourxml code here";

$feed = new SimplePie();
$feed->set_raw_data($xml);
$feed->init();
$feed->handle_content_type();
echo $feed->get_adress();
