我需要这个xml文件的文本在电报中使用它,如果xml没有“id”和“name”我可以做到,但没有标签
<root>
<origen>...</origen>
<trend>
<zone id="809" name="AGi">
<subzone id="809" name="AGi">
<text>
I want this text.
</text>
</subzone>
</zone>
</trend>
function getIdTEXT($chatId){
$context = stream_context_create(array('http' => array('header' => 'Accept: application/xml')));
$url = "http://www.thexmlfile/MM.xml";
$xmlstring = file_get_contents($url, false, $context);
$xml = simplexml_load_string($xmlstring, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($xml);
$array = json_decode($json, TRUE);
$info = "information: ".$array['trend']['zona id="809" nama="AGi"']['subzone id="809" nombre="AGi"']['text'];
sendMessage($chatId, $info);
}
您可以使用XPath
查询所需的确切节点:
$xml = simplexml_load_string($xmlstring);
$nodes = $xml->xpath("/root/trend/zone[@id = 809 and @name= 'AGi']/subzone[@id = 809 and @name = 'AGi']/text") ;
$text = (string)$nodes[0] ;
echo $text ; // I want this text.
您不必将SimpleXML对象转换为数组以从中访问值,您只需像对象变量一样访问它们:
$xml = simplexml_load_string($xmlstring, "SimpleXMLElement", LIBXML_NOCDATA);
echo $xml->trend->zone->subzone->text;
输出:
I want this text.
在xml中是'zone',但在php中你有'zona'。您不需要在数组键中添加id和name属性,只需添加标记名称即可。
$info = "information: ".$array['trend']['zone']['subzone']['text'];
