Java 如何将XML字符串添加到现有的BaseX数据库？
使用Java 如何将XML字符串添加到现有的BaseX数据库？,java,json,xml,nosql,basex,Java,Json,Xml,Nosql,Basex,使用org.json和关键的JSONArray而不是JSONObject，通过Twitter4J获得XML输出。然而，它被认为是： 当尝试验证时 但是，它至少具有XML的功能 假设BaseX将充分地处理XML，我希望将文档添加到数据库中，如下所示： new Open(databaseName).execute(context); for (int i = 0; i < tweets.length(); i++) { jsonStringTweet = twe
org.jsonJSONArrayJSONObjectTwitter4JXMLXMLBaseXXML new Open(databaseName).execute(context);
for (int i = 0; i < tweets.length(); i++) {
jsonStringTweet = tweets.get(i).toString();
jsonObjectTweet = new org.json.JSONObject(jsonStringTweet);
stringXml = XML.toString(jsonObjectTweet);
log.info(stringXml);
new Add(null, stringXml).execute(context);
}
