将GraphML转换为GV或Dot文件

Question

如何使用"graphml"文件作为输入在graphvis中绘制图形.
我知道为此目的graphvis而来,graphml2gv但当我尝试从命令提示符运行此命令时,我收到此消息
cvtgxl: not configured for conversion from GXL to GV

Answer 1

您的 Graphviz 副本是在没有 Expat 库的情况下编译的（要纠正，安装 Expat 并在运行后重新编译./configure --with-expat=yes）。

cmd/tools/graphml2gv.c：

#ifdef HAVE_EXPAT
    initargs(argc, argv);
    while ((inFile = getFile())) {
    while ((G = graphml_to_gv(nameOf(gname, gcnt), inFile, &rv))) {
        gcnt++;
        if (prev)
        agclose(prev);
        prev = G;
        if (Verbose) 
        fprintf (stderr, "%s: %d nodes %d edges\n",
            agnameof (G), agnnodes(G), agnedges(G));
        agwrite(G, outFile);
        fflush(outFile);
    }
    }
    exit(rv);
#else
    fputs("cvtgxl: not configured for conversion from GXL to GV\n", stderr);
    exit(1);
#endif
