xml2graph我已使用Nigel Small的转换器将 xml 文件转换为密码查询。结果，有一些空白节点作为xml格式的继承。CYPHER 查询是这样的（对不起，很长的帖子）：

CREATE

==============================

当我试图创建一个具有共同作者关系的图表时，我发出了这个查询：

START title=node:node_auto_index('title:*'), author = node:node_auto_index('name:*') 
MATCH a-[:author]->title<-[:author]-b 
CREATE UNIQUE a-[coaut:coautores]-b

在 neo4j 控制台上，但输出显示没有附加关系，数据库没有改变，虽然语法没问题。我想知道原因是来自 xml 的空白节点（记录、记录、作者）。有没有办法解决这个问题？原始文件很大，因此无法手动更正。我应该删除这些节点及其关系吗？奥布里加多，谢谢！
