我是R的新手，并且是第一次使用XML文件。已经从站点进行了大量发布，以将具有父级和多个子级的xml加载到R中的单个数据帧中。但是，要么行被重复，要么失败。
我要加载的xml文件格式
<?xml version="1.0" encoding="utf-8"?>

方法1
library(XML)
library(methods)
xml_raw<-xmlParse("test.xml",useInternalNodes = TRUE)
xml_data<-xmlToDataFrame(xml_raw)
我收到的错误消息如下所示
[<-.data.frame（*tmp*中的错误，i，名称（nodes [[i]]），值= c（“ Residential” ，：列的下标重复方法2
df<-ldply(xmlToList(xml_raw), function(x) { data.frame(x) } )
这会将文件加载到数据帧，但重复同一事务两次以上。附加输出屏幕截图。
我希望有一排的ConsumerOID包含所有详细信息，并且不再重复。它应该将所有父节点和子节点作为数据帧中的一列。
