XML ATOM到SimpleXML對象丟失數據

Question

嗨，我有一個簡單的問題。當我嘗試將一個原子XML字符串SimpleXML的對象或使用simplexml_load_data功能，它似乎下降不少屬性的數據..

像我原來的字符串我有

<?xml version="1.0" encoding="UTF-8"?> 
<feed gd:kind="customsearch#search" xmlns="http://www.w3.org/2005/Atom" xmlns:cse="http://schemas.google.com/cseapi/2010" xmlns:gd="http://schemas.google.com/g/2005" xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/"> 
<title>Google Custom Search - flower</title> 
<id>tag:www.googleapis.com,2010-09-29:/customsearch/v1?q=flower&amp;&amp;num=10&amp;start=1&amp;safe=off</id>

    <name>- Google Custom Search</name> 
</author> 
<updated>1970-01-16T10:55:22.093Z</updated> 
<opensearch:Url type="application/atom+xml" template="https://www.googleapis.com/customsearch/v1?q={searchTerms}&amp;num={count?}&amp;start={startIndex?}&amp;lr={language?}&amp;safe={cse:safe?}&amp;cx={cse:cx?}&amp;cref={cse:cref?}&amp;sort={cse:sort?}&amp;filter={cse:filter?}&amp;gl={cse:gl?}&amp;cr={cse:cr?}}&amp;googlehost={cse:googleHost?}&amp;c2coff={?cse:disableCnTwTranslation}&amp;hq={cse:hq?}&amp;hl={cse:hl?}&amp;siteSearch={cse:siteSearch?}&amp;siteSearchFilter={cse:siteSearchFilter?}&amp;exactTerms={cse:exactTerms?}&amp;excludeTerms={cse:excludeTerms?}&amp;linkSite={cse:linkSite?}&amp;orTerms={cse:orTerms?}&amp;relatedSite={cse:relatedSite?}&amp;dateRestrict={cse:dateRestrict?}&amp;lowRange={cse:lowRange?}&amp;highRange={cse:highRange?}&amp;searchType={cse:searchType?}&amp;fileType={cse:fileType?}&amp;rights={cse:rights?}&amp;imgsz={cse:imgsz?}&amp;imgtype={cse:imgtype?}&amp;imgc={cse:imgc?}&amp;imgcolor={cse:imgcolor?}&amp;alt=atom"/> 
<opensearch:Query role="request" title="Google Custom Search - flower" totalResults="98800000" searchTerms="flower" count="10" startIndex="1" inputEncoding="utf8" outputEncoding="utf8" cse:safe="off" cse:cx="g"/> 
<opensearch:Query role="cse:nextPage" title="Google Custom Search - flower" totalResults="98800000" searchTerms="flower" count="10" startIndex="11" inputEncoding="utf8" outputEncoding="utf8" cse:safe="off" cse:cx="0vv1rbg"/> 
<opensearch:totalResults>98800000</opensearch:totalResults> 
<opensearch:startIndex>1</opensearch:startIndex> 

，但是當我將其轉換爲xml使用

 $xml = simplexml_load_string($rs); 
     print_r($xml); 

我的輸出如下所示。像所有的設置已經一去不復返了總搜索結果數量，關鍵信息..

Answer 1

這些元素不走了，你就不能「看到」他們在一個標準的垃圾，因爲他們在不同的命名空間。您仍然可以在它們之間迭代這樣的：

foreach ($xml->children('opensearch', TRUE) as $element) { 
    echo $element->getName(), "\n"; 
} 

凡'opensearch'表示命名空間前綴和TRUE意味着你使用的文檔特定的前綴，而不是完整的命名空間URL。
