extract data from XML files - R - r

Question

I'm new to extracting data from XML file. I'm trying to process the following an XML file using R XML packages. The information I want is in the attribute values.
I encounter two difficulties:
some attribute values exist in one node, but not in another node. For example, "DRP" has the information in the second but not in the first
some attributes has multiple values for an individual and i don't know how to link them to that individual. For example, "EmpHs" has multiple records for an individual (identified by indvlPK).
Ideally I want the output data has the structure similar to the following:
lastNm
firstNm
indvlPK
fromDt
orgNm
hasCustComp

Is there any way I can parse the data correctly? Thanks!
The code I used but didn't give me what I want:
doc <- "Test.xml"
ind <- xmlParse(doc)
xmltop = xmlRoot(ind)
temp1 <- data.frame(unlist(getNodeSet(xmltop,"//Info/#lastNm")))
temp2 <- data.frame(unlist(getNodeSet(xmltop,"//Info/#firstNm")))
temp3 <- data.frame(unlist(getNodeSet(xmltop,"//Info/#indvlPK")))
temp4 <- data.frame(unlist(getNodeSet(xmltop,"//EmpHs/#fromDt")))
temp5 <- data.frame(unlist(getNodeSet(xmltop,"//DRP/#hasCustComp")))
The data is here:
