我想将一个点文件加载到python,使用这个

graph = pydot.graph_from_dot_file(tmp1)

nodeList = graph.get_node_list()

但是当点文件中的节点标签如下时出现错误:

第398章

错误信息是这样的:

  398 [shape=diamond, fillcolor="#CCCCCC", label="(int)*value == '\\\"'"];
      ^
Expected "}" (at char 1800), (line:34, col:7)
Traceback (most recent call last):
  File "dotchange.py", line 52, in <module>
    print dotchange(line)
  File "dotchange.py", line 13, in dotchange
    nodeList = graph.get_node_list()
AttributeError: 'NoneType' object has no attribute 'get_node_list'

似乎转义字符"\"会导致错误。

"\"如果我用 替换节点的标签"",错误就会消失。
