PHP - SimpleXMLElement - 如何访问此元素
PHP - SimpleXMLElement - How to Access this element
我正在尝试访问我的简单XML元素“数组”中的一个元素。
我的 XML 看起来像这样:
<?xml version="1.0" encoding="UTF-8"?>
<changeinfo>
<changes app_ver="01.16">
<![CDATA[
Minor interface changes
Please visit http://community.wbgames.com/t5/Mortal-Kombat-X/ct-p/MKX for more details.
]]>
</changes>
<changes app_ver="01.15">
<![CDATA[
WBPlay unlockables no longer requires WBPlay
]]>
</changes>
<changes app_ver="01.14">
<![CDATA[
General Game Play and Balance Tweaks

用 simplexml_load_string()
加载它得到以下 var_dump 结果:
object(SimpleXMLElement)#40 (1) {
["changes"]=>
array(16) {
[0]=>
object(SimpleXMLElement)#39 (1) {
["@attributes"]=>
array(1) {
["app_ver"]=>
string(5) "01.16"
}
}
[1]=>
object(SimpleXMLElement)#41 (1) {
["@attributes"]=>
array(1) {
["app_ver"]=>
string(5) "01.15"
}
}
[2]=>
object(SimpleXMLElement)#42 (1) {
["@attributes"]=>
array(1) {
["app_ver"]=>
string(5) "01.14"
}
}
}
如何访问我想要其内容的 changes
条目?
例如,我该怎么做:
echo $xml->changes['01.16'];
期待输出第一个条目内容(Minor interface changes ...
)?
试试这样的东西:
$string = <<<XML
[your xml above]
XML;
$xml = simplexml_load_string($string);
$results = $xml->xpath('.//changes[@app_ver="01.16"]');
echo (trim($results[0]));
输出:
Minor interface changes
