我有一个美国的SVG文件，我正在尝试从ID和Class标签获取的状态和区域中创建数组。我在php和js工作。我必须将文件拉入我使用file_get_contents（usa.svg）执行的map.php文件中。我想让它像json数据一样格式化。我包含了一些SVG文件来显示我想要做的事情。任何帮助表示赞赏谢谢。如果可能，我试图使区域数组类似于字典，其中状态为区域的值（键）。
以下代码：

获取所有路径，然后缩减为class属性，将为您提供各种方式 - 最后由您决定如何格式化。
const dictionary = [...document.getElementsByTagName('path')].reduce((acc, state) => {
acc[state.class] = acc[state.class] ? [...acc[state.class], state.id] : [state.id]
return acc;
}, {})
希望我理解正确！

您可以使用SimpleXML来解析SVG源，并遍历这些区域。循环遍历状态并推入阵列。最后，您可以使用json_encode()来获得预期的输出。
$data = [];
$xml = simplexml_load_file('usa.svg');
foreach ($xml->g->g as $region) {
$region_name = (string)$region['id'];
foreach ($region->g as $state) {
$data[$region_name][] = (string)$state['id'];
}
}
$json = json_encode($data);
echo $json ;
输出（类似）：
{
"northEast":["newHampshire","vermont","maine","rhodeIsland","newYork","pennsylvania","newJersey","connecticut","massachusetts"],
"middleWest":["ohio","indiana","illinois","wisconsin"]
}
要对数据进行排序，您可以使用（json_encode()之前）：
$data = array_map(function($arr) { sort($arr); return $arr; }, $data);
ksort($data);
