我正在尝试用php阅读这个XML文档。
这就是我到目前为止所知道的。
$xml = new SimpleXMLElement(file_get_contents(TEMPLATEPATH.'/lib/regions.xml'));
echo $xml->Children[0]->SimpleGeoName[0]->Id;
我不知道如何循环遍历所有国家并使用php存储它们。我是xml解析的新手，我甚至不确定我是否能够像这样循环所有结果。因为$xml->Children->..返回空。
任何帮助都非常感激。

这是您浏览xml
echo "<pre>";
$xml = new SimpleXMLElement(file_get_contents("regions.xml"));
foreach ( $xml->Children as $region ) { // iterate through all the regions
foreach ( $region as $continent ) {
echo "Continet ID :", $continent->Id . PHP_EOL;
echo "Continet Name :", $continent->Name . PHP_EOL;
echo PHP_EOL;
foreach ( $continent->Children as $countryList ) {
foreach ( $countryList as $country ) {
// var_dump($country);
echo "\tCountry ID :", $country->Id . PHP_EOL;
echo "\tCountry Name :", $country->Name . PHP_EOL;
echo PHP_EOL;
}
}
}
}

您的xml值现在是一个php对象。你可以运行
var_dump($xml);
exit;
这将打印出发送给您的任何令人发指的复杂xml对象结构。然后，您将能够查看要运行foreach循环的子对象，以获取仅国家/地区名称的列表。祝你好运。
答案 2 :(得分：0)
SimpleXMLElement不是那么简单，事实上只有当你猜测如何处理它时才能获得简单 ......或者有人建议你。< / p>
假设regions.xml是这样的：
<regions>
<region id="01" size="big">
New Zealand
</region>
<region id="02" size="small">
Tokelau
</region>
</regions>
以下PHP代码可以浏览该XML文档：
$xml = new SimpleXMLElement('regions.xml');
foreach ($xml->region as $region) { // iterate through all the regions
echo 'Region ID: '. (string)$region['id']; // get the attribute id
echo 'Region size: '. (string)$region['size']; // get the attribute size
echo 'Region name: '. (string)$region; // get the contents of the
// element by casting it to a string
}
现在让我们做一些事情......假设<region>有一个子元素<subregion>。
<regions>
<region id="01" size="big">
<name>USA</name>
<subregion id="01_1">Alaska</subregion>
</region>
...
</regions>
如果你想获得每个地区的所有子区域，你必须这样做：
$xml = new SimpleXMLElement('regions.xml');
foreach ($xml->region as $region) { // iterate through all the regions
foreach ($region->subregion as $subregion) // iterate trough the subregion of $region
// do something
}
}
您的文档结构似乎比这更复杂，但使用这些基础知识可以轻松完成。
