I am attempting to use XML package and xpathSApply() to extract, say, the eValue attribute
for eName=='0ne' for all <File> nodes that have <FileTypeId>==10. I try the
following, amoung several things:
getNodeSet(doc,
"//File[FileTypeId/text()='10']/patientcharacteristi...@ename='one']/@eValue")
should do it.
You need to compare the text() of the FileTypeId node.
And the / after the PatientCharacterstics and before the [] will cause
trouble.
HTH,
D.
doc<-xmlInternalTreeParse(Manifest)
Root = xmlRoot(doc)
xpathSApply(Root,
"//File[FileTypeId=10]/PatientCharacteristics/[...@ename='one']", xmlAttrs)
and it does not work.
Might somebody help me with the syntax here?
Thanks a lot!!
