I am trying to read through the registered user list so I can get an access list available for viewing.
_, _, tag = string.find(sLine, "(<.*>).*")
i thought the function only replied back with the result that was within the ()s but when i print out the value of 'tag' it shows the entire line 'Jemte' ive tried using '%S+' instead of '.*' but then the tag is 'nil'.
any suggestions/help would be appreciated.
ok i found out that the <(.*)> reads from the beginning of the line til the end
Jemte returns 'Nick>Jemte
i tried "<(%S+)>(%w+)<(%S+)>" for the pattern but its not working...ill keep trying tho
%b<>(.+)%b<>
means: anything surrounded by 2 thingies that are < and >
More precise would be to assign the variable name as well.
Like:
local _,_,varname,value=string.find(line,"<(.+)>(.+)%b<>")
-- and then:
table[varname]=value
its far more better to use frmHub:GetRegisteredUsers() ..
but if you are trying to parse an xml you need to scan the string( contents of xml file ) progressively rather than pMatched..
str = [[
Smth
SmthElse
SmMore
SmMore
]]
you need to get the first tag..
s,e, sTag, sRest = string.find( str, "<([^>]+)>(.*)" )then you need to get the contents of that tag..
s,e, sContents, sTmp = string.find( sRest, "(.-)(.-)" )This is the main principle to parse the xml.. Carrying on from here you'll need to create a function with a while-loop to parse the sContents and the sTmp, putting the [sTag]= sContents inside a table.
That all has been done for you .. Look in the how to section There is a function I played with for a while ..
Btw:
as far as pattern matching is concerned '-' means not greedy in the results.. while '*' means greedy..
Example:
str = "12"
string.find ( str, "<(.*)>" )
-- this will result in "one>12string.find( str, "<(.-)>" )
-- this will result in "one"I hope its clear ;)
