In an XML response I get from the web there is one part of the data that is structured as follows:
<votos>
<Deputado Nome="Roberto Britto" ideCadastro="141529" Partido="PP " UF="BA" Voto="Sim "/>
<Deputado Nome="Luiz Argôlo" ideCadastro="160547" Partido="PP " UF="BA" Voto="Sim "/>
<Deputado Nome="José Carlos Araújo" ideCadastro="74140" Partido="PSD " UF="BA" Voto="Sim "/>
</votos>
I parsed the file as follows:
doc <- xmlTreeParse(raw_result,useInternal=TRUE)
rootNode <- xmlRoot(doc)
And then tried to create a data frame of the node I showed in the beginning as follows:
rootvotacao <- rootNode[[4]][[1]][[2]]
votacao2 <- xmlSApply(rootvotacao, function(x) xmlSApply(x, xmlValue))
votacao2_df <- data.frame(t(votacao2),row.names=NULL)
However, I only get a table with two columns for each Deputado
and one row containing list()
.
What I wanted is to get a table, a row for each Deputado
and 5 columns: Nome
, ideCadastro
, Partido
, UF
, Voto
.
Any thoughts? Thanks!
You can use XML
package and xmlToList
to get this done.
library(XML)
raw_result <- '<votos>
<Deputado Nome="Roberto Britto" ideCadastro="141529" Partido="PP " UF="BA" Voto="Sim "/>
<Deputado Nome="Luiz Argôlo" ideCadastro="160547" Partido="PP " UF="BA" Voto="Sim "/>
<Deputado Nome="José Carlos Araújo" ideCadastro="74140" Partido="PSD " UF="BA" Voto="Sim "/>
</votos>'
#i faced encoding issue hence
raw_result <- iconv(raw_result,'latin1','utf-8')
do.call(rbind,xmlToList(raw_result))
Output:
> do.call(rbind,xmlToList(raw_result))
Nome ideCadastro Partido UF Voto
Deputado "Roberto Britto" "141529" "PP " "BA" "Sim "
Deputado "Luiz Argôlo" "160547" "PP " "BA" "Sim "
Deputado "José Carlos Araújo" "74140" "PSD " "BA" "Sim "
