我想从其中一个项目标签中获取数据.要访问此标签，我使用以下 xpath:
I want to get the data from one of the item tags. To get to this tag, I use the following xpath:
$description = $xml->xpath("//item[@title='0x|Beschrijving']");
这确实以以下形式返回一个数组:
This does indeed return an array in the form of:
Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[id] => 787900813228567
[view] => 12000
[title] => 0x|Beschrijving
[engtitle] => 0x|Description
)
)
)
但是实际信息(存储在项目标签之间)在哪里?我一定是做错了什么，但我无法弄清楚那可能是什么......可能真的很简单......帮助将不胜感激.
But where is the actual information (that is stored between the item tags) located? I must be doing something wrong, but I can't figure out what that might be... Probably something really simple... Help would be appreciated.
推荐答案
当你加载 XML 文件时，你需要处理 CDATA.. 这个例子有效:
When you load the XML file, you'll need to handle the CDATA.. This example works:
<?php
$xml = simplexml_load_file('file.xml', NULL, LIBXML_NOCDATA);
$description = $xml->xpath("//item[@title='0x|Beschrijving']");
var_dump($description);
?>
输出如下:
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"
}
}
