GraphMLでXML出力を調整する

Question

GraphMLからxml出力を調整できると思いますか？

GraphML wikiでタグが固定されているように見える：私はあなたがタグの属性を変更することができることがわかりました

<graphml> 
    <graph> 
    <node> 
     <data></data> 
    </node> 
    <edge> 
     <data></data> 
    </edge> 
    </graph> 
</graphml> 

。 タグ自体を<car></car>のようにカスタマイズできると思いますか？

新しい要素を追加する必要がある場合は、the DTDを変更する必要があります。その場合、データはGraphMLではなく、DTD customizationのために独自の標準になります。

<!-- ====================================================================== --> 
<!-- file: graphml.dtd ====================================================== 

    This is the Document Type Definition for the release candidate of 
    GraphML version 1.0 and represents a (necessarily) looser specification 
    than the corresponding XML Schema. It's use is discouraged, though it 
    may be necessary for some systems. 

    Usage: 

      SYSTEM "http://graphml.graphdrawing.org/dtds/1.0rc/graphml.dtd" 

      xmlns="http://graphml.graphdrawing.org/xmlns/1.0rc" 

    ====================================================================== --> 

<!-- ===============================================================--> 
<!--Parameter entity for data content --> 
<!--================================================================--> 

<!ENTITY % GRAPHML.data.content "(#PCDATA)">

<!--Parameter entities for attribute list extensions -->
