如何從XML動態添加邊緣而不丟失源或目標

Question

我想從xml文件構建圖形，但只加載基於特定條件的節點...我可以獲取所有要添加的頂點對於包括解碼，並添加功能循環，

問題是邊緣..我可以讓他們有來源，但目標始終之間的很多事情我想最終版本拉閘空

添加XML節點添加到數組中，並且只有在將所有頂點添加到圖之後，才能對邊進行解碼...但這仍然不起作用...

function get_selected(main_class, filename){ 
    "use strict"; 
    var node, i, j, req, root, decj, deci, enc, dec, data, parent, graph, main_class_node, child_nodes, edges, destinations; 
    deci = new mxCodec(); 
    decj = new mxCodec(); 
    graph = new mxGraph(); 
    parent = graph.getDefaultParent(); 

    req = mxUtils.load(filename); 
    root = req.getDocumentElement(); 

    child_nodes = []; 
    edges = []; 
    destinations = []; 

    mxLog.show(); 
    for (i=0; i < root.childNodes[0].childNodes.length; i ++) { 
     // Get the main cell and add it to the graph 
     if (root.childNodes[0].childNodes[i].id == main_class) { 
      node = deci.decode(root.childNodes[0].childNodes[i]); 
      main_class_node = graph.getModel().add(parent, node); 
     } 
     //get all the children of the main cell and add them to the graph 
     else if (root.childNodes[0].childNodes[i].outerHTML.indexOf('parent="' + main_class + '"') != -1) { 
      node = decj.decode(root.childNodes[0].childNodes[i]); 
      graph.getModel().add(main_class_node, node); 
      child_nodes.push(node.id); 

     } 
    } 
    for (j=0; j < child_nodes.length; j ++) { 
     for (i=0; i < root.childNodes[0].childNodes.length; i ++) { 
      //get all the edges originating in any of the "chidren" and add them to the graph 
      if (root.childNodes[0].childNodes[i].outerHTML.indexOf('source="' + child_nodes[j] + '"') != -1) { 
       node = root.childNodes[0].childNodes[i]; 
       //graph.getModel().add(parent, node); 
       edges.push(node); 
      } 
     } 
    } 
    for (j=0; j < edges.length; j ++) { 
     for (i=0; i < root.childNodes[0].childNodes.length; i ++) { 
      //get the target of each of the edges and and add them to the graph 
      if (root.childNodes[0].childNodes[i].id == "attr-" + edges[j].id.split('-')[1]) { 
       node = deci.decode(root.childNodes[0].childNodes[i]); 
       graph.getModel().add(parent, node); 
      } 
     } 
    } 
    dec = new mxCodec(); 

    for (j=0; j < edges.length; j ++) { 
     node = dec.decode(edges[j]); 
     graph.getModel().add(parent, node); 
    } 

    enc = new mxCodec(); 
    data = enc.encode(graph.getModel()); 
    return mxUtils.getXml(data); 
}

我的問題是有多個mxCodecs ...我已經做了許多改變的代碼，但這是基本問題
