Lua Parser to get one String

[ShrinidhiShastr]

Hi

There is a requirement to fetch first string present in the met-key web.page. The web.page meta-key value looks something like below. The length of the string is variable in nature and the number of strings can be variable in nature.

web.page="/String01/String02/String03.aspx"

I need to get only the first string (String01) as an additional meta-key (lets say meta_new). Please let me know how can I achieve this using LUA parser.

Regards

This should do it.

local getFirstString = nw.createParser("getFirstString", "")

getFirstString:setKeys({
    nwlanguagekey.create("meta_new")
})

function getFirstString:onMeta(idx, vlu)
    if vlu then
        local firstString = string.match(vlu, "^/([^/]+)/")
        if firstString then
            nw.createMeta(self.keys["meta_new"], firstString)
        end
    end
end

getFirstString:setCallbacks({
    [nwlanguagekey.create("web.page")] = getFirstString.onMeta
})

Another way I had tried in the past I commented on in a previous post.
