XML to graph by JGraphX API

问题

I need to parse XML to a graph in JGraphX using Java. I get this XML from the JGraphX library and need to again set a graph by this XML. Is there any JGraphX library method that converts XML to a graph? I have this this below code to get XML from a graph:

try
{
    System.out.println("call xml getting code");
    mxCodec codec = new mxCodec();
    String xml = mxUtils.getXml(codec.encode(graph1.getModel()));
    java.io.FileWriter fw = new java.io.FileWriter("E:\\my-file.xml");
    fw.write(xml);
    fw.close();
}
catch(Exception ex)
{
    System.out.println("ERROR : "+ex.getMessage());
}  

So is there any way to get a graph from this XML? Otherwise what should I do to generate the graph? If I try to generate a graph by reading the XML one by one it may take time with complex algorithms hence I tried to find other library method.

回答1:

This should read it from the specified Path into a new mxGraph

mxGraph graph = new mxGraph();        
try
{
    Document document = mxXmlUtils.parseXml(mxUtils.readFile(filePath));
    mxCodec codec = new mxCodec(document);
    codec.decode(document.getDocumentElement(), graph.getModel());
}
catch (Exception ex)
{
    ex.printStackTrace();
}
