How export to xml file!

[aye nwe thaing]

Hi Dear all,

I use xml file to import graph to orientdb graph database. It is ok and very useful to me. But I want to know can we export data from orientdb to xml file format. If it can, I want to know the procedure to export xml file format.


Be happy


Thanks to all.

Hi,

An easy way to export current graph database in GraphML (xml) format is Gremlin saveGraphML().

From OrientDB Console:

> gremlin g.saveGraphML(filename.xml)

HTH,

Hi Dear all,

I try to code to export graph to XML file.

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;

import javax.xml.stream.XMLStreamException;

import com.tinkerpop.blueprints.pgm.impls.orientdb.OrientGraph;
import com.tinkerpop.blueprints.pgm.util.graphml.GraphMLReader;
import com.tinkerpop.blueprints.pgm.util.graphml.GraphMLWriter;

public class TestLoadGraph {
    public static void main(String[] args) throws Exception {
    OrientGraph g = new OrientGraph("local:C:/orientdb-graphed-1.0rc8/databases/Test_3");
    GraphMLReader.inputGraph(g, new FileInputStream(
    "C:/orientdb-graphed-1.0rc8/data/Test_3.xml"));
    g.shutdown();

    g = new OrientGraph("local:C:/orientdb-graphed-1.0rc8/databases/Test_3");
    FileOutputStream fo = new FileOutputStream("C:/orientdb-graphed-1.0rc8/data/Test_5.xml");
    GraphMLWriter.outputGraph(g, fo);
    g.shutdown();

    }
    }

But the following error occurs. How can i solve this problem?

Exception in thread "main" java.lang.NoSuchMethodError: com.orientechnologies.orient.core.record.impl.ODocument.fieldNames()Ljava/util/Set;

Hi,

Have you tried with the last official release?

http://code.google.com/p/orient/downloads/detail?name=orientdb-graphed-1.0.1.zip

HTH,

For others trying to get a GraphML export from orientdb, I wrote a quick n dirty nodejs tool that will convert orientdb's JSON export format to GraphML. https://github.com/lukeasrodgers/odb2graphml 

Handy if you aren't familiar with Java.
