如何将其转换为关联数组，而不会丢失＆＃39;规格＆＃39;中的属性。元件。
目前我有这个：
$item_xml = simplexml_load_string($this->xml_parser->readOuterXML(), 'SimpleXMLElement', LIBXML_NOCDATA);
这适用于最顶层的元素。但是对于specs元素，我丢失了所有属性信息，并且只得到一个包含每个spec元素值的平面数组。有任何想法吗？
答案 0 :(得分：0)
看输出。我觉得一切都好的
foreach($item_xml->specs->spec as $spec) {
foreach( $spec->attributes() as $att )
echo $att ."\n";
}
答案 1 :(得分：-1)
我使用这个功能，它已经老了，我没有编码，但效果很好。如果你想要属性，那么让get_attributes param为1.如果你想了解更多，请在评论中提供一个链接。
/**
* xml2array() will convert the given XML text to an array in the XML structure.
* Link: http://www.bin-co.com/php/scripts/xml2array/
* Arguments : $contents - The XML text
* $get_attributes - 1 or 0. If this is 1 the function will get the attributes as well as the tag values - this results in a different array structure in the return value.
* $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance.
* Return: The parsed XML in an array form. Use print_r() to see the resulting array structure.
* Examples: $array = xml2array(file_get_contents('feed.xml'));
* $array = xml2array(file_get_contents('feed.xml', 1, 'attribute'));
