将XML解析为JSON
我有一个XML文件,例如
<stock><name>AXL</name><time>19-07</time><price>11.34</price></stock><stock><name>AIK</name><time>19-07</time><price>13.54</price></stock>
<stock><name>ALO</name><time>19-07</time><price>16.32</price></stock>
<stock><name>APO</name><time>19-07</time><price>13.56</price></stock>
...............more
如何将其解析为JSON结构文件?
回答:
对于一个简单的解决方案,我建议使用Jackson库,它是一个Java库,用于生成和读取带有XML扩展名的JSON,因为它只需几行简单的代码就可以将任意复杂的XML转换为JSON。
<entries> <stock><name>AXL</name><time>19-07</time><price>11.34</price></stock>
<stock><name>AIK</name><time>19-07</time><price>13.54</price></stock>
<stock><name>ALO</name><time>19-07</time><price>16.32</price></stock>
<stock><name>APO</name><time>19-07</time><price>13.56</price></stock>
</entries>
import java.io.File;import java.util.List;
import org.codehaus.jackson.map.ObjectMapper;
import com.fasterxml.jackson.xml.XmlMapper;
public class Foo
{
public static void main(String[] args) throws Exception
{
XmlMapper xmlMapper = new XmlMapper();
List entries = xmlMapper.readValue(new File("input.xml"), List.class);
ObjectMapper jsonMapper = new ObjectMapper();
String json = jsonMapper.writeValueAsString(entries);
System.out.println(json);
// [{"name":"AXL","time":"19-07","price":"11.34"},{"name":"AIK","time":"19-07","price":"13.54"},{"name":"ALO","time":"19-07","price":"16.32"},{"name":"APO","time":"19-07","price":"13.56"}]
}
}
该演示使用Jackson
1.7.7(较新的1.7.8也可以使用),Jackson XML
Databind 0.5.3(尚未与Jackson 1.8兼容)和Stax2
3.1.1。
