Question

我已经使用Nigel Small的xml2graph转换器将xml文件转换为cypher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（对于长篇文章感到抱歉）：

CREATE
(N0),
(N1 {publicationDate:"2007-12-18",
    title:"RECONHECIMENTO E AGRUPAMENTO",`title     language`:"por"}),

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

当我尝试使用co-autorship关系创建图表时，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，但输出显示没有其他关系，数据库没有改变，虽然语法没问题。我想知道原因是来自xml（记录，记录，作者）的空白节点。有什么方法可以解决这个问题吗？原始文件很大，因此手动校正是不可行的。我应该删除这些节点及其关系吗？ Obrigado，谢谢！
