Hi,
Using ruby script to parse xml, I'd like to make an XPATH's like command ,
completelist from currentnode in xml.
This works fine and I can choose one of childnodes.
Then I call helper#XpathNavNode( to update currentnode but it fails :
g:currentnode does not exists anymore.
Can you see why ?
Thank you
command! -nargs=1 -bang -complete=customlist,helper#XpathList
\ XPATH call helper#XpathNavNode("<bang>", <f-args>)
fun! helper#XpathList(A,L,P) "{{{
au CmdlineLeave * unlet! g:currentnode
if !exists('g:currentnode')
let g:currentnode=''
endif
let g:currentnode.='/'.a:A
ruby << EOF
require 'ox'
require 'open-uri'
# 0. on one xml file
xmlpath = ENV['tmp']+"/localConf.xml"
doc = Ox.parse(open(xmlpath).read)
# 1. retrieve all sorted child possible elements'name
arr = doc.root.locate('*' + Vim::evaluate('g:currentnode'))
arr_out = {}
arr.each { |a|
a.each {|key, value|
arr_out[key.value]=""
}
}
# 2.Proposal Array/Vim'List returned
Vim::command("return " + arr_out.keys().to_s )
EOF
endfunction "}}}
fun! helper#XpathNavNode(...) "{{{
" update currentnode from user's choice.
let g:currentnode=a000[1]
call feedkeys(':XPATH '.g:currentnode,'n')
endfunction "}}}
