[英]Parsing XML in PHP returns SimpleXMLElement Object. What next?
下面是我嘗試解析從美國國會圖書館SRU服務返回的XML代碼進行圖書搜索時得到的響應。 如何查看[recordData] => SimpleXMLElement對象以獲取標題,創建者,發布者信息? 這是我第一次鑽研XML。 任何幫助將不勝感激。 這是我得到的回應。 我找到了處理名稱空間的代碼,但無法弄清楚如何超越recordData標記。
SimpleXMLElement Object
(
[version] => 1.1
[numberOfRecords] => 1
[records] => SimpleXMLElement Object
(
[record] => SimpleXMLElement Object
(
[recordSchema] => info:srw/schema/1/dc-v1.1
[recordPacking] => xml
[recordData] => SimpleXMLElement Object
(
)
[recordPosition] => 1
)
)
$entry=simplexml_load_file('xml_data.xml');
$namespaces = $entry->getNameSpaces(true);
$yr = $entry->children($namespaces['zs']);
print_r($yr);

一個簡單的例子顯示:
foreach( $xmldata->children() AS $child )
{
//run any query you want on the children.. they are also nodes.
$name = $child->getName();
}
