实际上我正在尝试使用java库从HTML源页面解析schema.org Microdata。我尝试了很多站点，最后我找到了来自https://maps.googleapis.com/maps/api/directions/json的任何23和Mf2j。对于.apache any23我找不到合适的文档所以我离开了，最后使用Mf2j我构建项目，我得到了jar。我创建了一个示例项目来执行Mf2j来解析Microdata。这是我写的示例代码。
package org.mypro;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URI;
import java.net.URISyntaxException;
import java.net.URL;
import java.util.Map;
import java.util.Properties;
import java.util.Map.Entry;
import com.kylewm.mf2j.Mf2Parser;
public class MySample {
/**
* @param args
* @throws URISyntaxException
* @throws IOException
*/
public static void main(String[] args) throws IOException, URISyntaxException {
// TODO Auto-generated method stub
Mf2Parser parser = new Mf2Parser()
.setIncludeAlternates(true)
.setIncludeRelUrls(true);
URL server = new URL("http://blogbasics.com/examples-of-blogs/");
Properties systemProperties = System.getProperties();
systemProperties.setProperty("http.proxyHost","pp.xyz.com");
systemProperties.setProperty("http.proxyPort","1234");
HttpURLConnection connection = (HttpURLConnection)server.openConnection();
connection.connect();
Map<String,Object> parsed = parser.parse(new URI("http://blogbasics.com/examples-of-blogs/"));
for (Entry<String, Object> string : parsed.entrySet()) {
System.out.println(string.getKey() +" = "+string.getValue());
}
}
}
但我得到了这样的输出。我得到了图像URL，但我需要所有Microdata元数据。

实际上我需要这种形式的输出，而不是json格式。我需要像这样的数据内容。我使用来自github的JavaScript Microdata Parser找到了这个，但我需要在java中使用相同类型的解析器。请建议我。感谢
