我想从其中一个商品标签中获取数据。要获得此标记,我使用以下xpath:
$description = $xml->xpath("//item[@title='0x|Beschrijving']");
这确实以以下形式返回数组:
Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[id] => 787900813228567
[view] => 12000
[title] => 0x|Beschrijving
[engtitle] => 0x|Description
)
)
)
但实际信息(存储在项目标签之间)位于何处?我一定做错了什么,但我无法弄清楚那可能是什么......可能是非常简单的事情......帮助会受到赞赏。

加载XML文件时,您需要处理CDATA ..此示例有效:
<?php
$xml = simplexml_load_file('file.xml', NULL, LIBXML_NOCDATA);
$description = $xml->xpath("//item[@title='0x|Beschrijving']");
var_dump($description);
?>
这是输出:
array(1) {
[0]=>
object(SimpleXMLElement)#2 (2) {
["@attributes"]=>
array(4) {
["id"]=>
string(15) "787900813228567"
["view"]=>
string(5) "12000"
["title"]=>
string(15) "0x|Beschrijving"
["engtitle"]=>
string(14) "0x|Description"
}
[0]=>
string(41) "Dit college leert studenten hoe ze een on"
}
}

我相信它等同于对象上的__toString()方法,所以
echo $description[0];
应该显示它,或者你可以施展它;
$str = (string) $description[0];
答案 2 :(得分:2)
查看PHP.net文档中的“SimpleXMLElement”(http://uk.php.net/manual/en/function.simplexml-element-children.php),看起来将节点转换为字符串“(string)$ value;”诀窍。
如果失败了,那个页面上有很多例子可以指出你正确的方向!

$description = $xml->xpath("//item[@title='0x|Beschrijving']");
while(list( , $node) = each($description)) {
echo($node);
}
