我在使用xml文件在谷歌地图上显示标记时遇到问题

这是我的xml文件“example.xml”

Html代码是：

<!DOCTYPE html >
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>

PHP/MySQL和googlemaps示例

地图创建得很好，但没有标记。。。提前感谢您的帮助。

将XML改为以下示例

<?xml version="1.0"?>
<markers>
  <marker>
     <name>Pan Africa Market</name>
     <address>1521 1st Ave, Seattle, WA</address>
     <lat>47.608940</lat>
     <lng>-122.340141</lng>
     <type>"restaurant"<type/>
  </marker>
  <marker>
    <...>Next marker info</...>
  </marker>
</markers>


泛非市场
华盛顿州西雅图第一大道1521号
47.608940
-122.340141
“餐厅”
下一个标记信息

Google Maps Api使用XPost XML格式

如果添加控制台日志记录，您能否找到

标记

数组的外观？

<?xml version="1.0"?>
<markers>
  <marker>
     <name>Pan Africa Market</name>
     <address>1521 1st Ave, Seattle, WA</address>
     <lat>47.608940</lat>
     <lng>-122.340141</lng>
     <type>"restaurant"<type/>
  </marker>
  <marker>
    <...>Next marker info</...>
  </marker>
</markers>
