如何将 XML 字符串添加到现有 BaseX 数据库？

Question

Using org.json and, crucially, JSONArray rather than JSONObject , managed to, seemingly at least , get XML output through Twitter4J . However, it shows as:

The Markup In The Document Following The Root Element Must Be Well-formed., Line '1', Column '98'.
The Markup In The Document Following The Root Element Must Be Well-formed.

When validation is attempted.

It does, however, have at least the appearance of XML .

Assuming that BaseX will wrangle the XML sufficiently, I'm looking to add the document to a database as:

    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);
    }

With reference to:

Constructor Detail

Add public Add(java.lang.String path) Constructor, specifying a target path. The input needs to be set via Command.setInput(InputStream). Parameters: path - target path, optionally terminated by a new file name Add public Add(java.lang.String path, java.lang.String input) Constructor, specifying a target path and an input. Parameters: path - target path, optionally terminated by a new file name. If null, the name of the input will be set as path. input - input file or XML string

However, I don't quite follow the requirements. The input seems to say that it will work with an XML string, which, presumably is what is being passed. Is that the correct way to add XML to a database?

Java Code:

package basex;

import java.net.MalformedURLException;
import java.net.URL;
import java.util.Properties;
import java.util.logging.Logger;
import org.basex.core.BaseXException;
import org.basex.core.Context;
import org.basex.core.cmd.Add;
import org.basex.core.cmd.Open;
import org.basex.core.cmd.CreateDB;
import org.basex.core.cmd.DropDB;
import org.basex.core.cmd.List;
import org.basex.core.cmd.Set;
import org.json.XML;
import twitter4j.JSONArray;
import twitter4j.JSONException;

public class DatabaseHelper {

    private static final Logger log = Logger.getLogger(DatabaseHelper.class.getName());
    private Properties properties = new Properties();
    private URL url = null;
    private String databaseName = null;
    private Context context = null;
    private String parserType = null;

    private DatabaseHelper() {
    }

    public DatabaseHelper(Properties properties) {
        this.properties = properties;
    }

    private void init() throws MalformedURLException, BaseXException {
        log.fine(properties.toString());
        parserType = properties.getProperty("parserType");
        url = new URL(properties.getProperty(parserType + "URL"));
        databaseName = properties.getProperty("databaseName");
        context = new Context();
        list();
    }

    private void list() throws BaseXException {
        log.fine(new List().execute(context));
    }

    private void drop() throws BaseXException {
        new Set("parser", parserType).execute(context);
        new DropDB(databaseName).execute(context);
        list();
    }

    private void create() throws BaseXException, JSONException {
        new Set("parser", parserType).execute(context);
        new CreateDB(databaseName).execute(context);
        new List().execute(context);
        list();
    }

    private void add(JSONArray tweets) throws JSONException, BaseXException {
        long id = 0L;
        String jsonStringTweet = null;
        org.json.JSONObject jsonObjectTweet = null;
        String stringXml = null;

        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);
        }
    }

    public void dropCreateAdd(JSONArray tweets) throws MalformedURLException, BaseXException, JSONException {
        init();
        drop();
        create();
        add(tweets);
        list();
    }

}

sorta kinda works, at least can add an XML file:
