arguments - Clojure: Pass 'expanded' optional args to function -

-

i'm new clojure , i'm stuck on how 'expand' function's optional args can sent function uses optional args (but wants args keywords not seq of keywords).

i'm parsing xml , if hard code values below function works, walks xml , finds value of 'title':

; zd required [clojure.data.zip.xml :as zd] ; ... (defn get-node-value [parsed-xml & node-path]   (zd/xml-> (zip/xml-zip parsed-xml) :item :title zd/text))  (get-node-value parsed-xml)

what want use 'node-path' pass in number of keywords, when written below comes in sequence of keywords throws exception:

(defn get-node-value [parsed-xml & node-path]   (zd/xml-> (zip/xml-zip parsed-xml) node-path zd/text))  (get-node-value parsed-xml :item :title) ; classcastexception clojure.lang.arrayseq cannot cast clojure.lang.ifn  clojure.data.zip/fixup-apply (zip.clj:73)

thanks!

i think looking apply (http://clojuredocs.org/clojure_core/clojure.core/apply)

(defn get-node-value [parsed-xml & node-path]   (let [params (concat node-path [zd/text])]     (apply zd/xml-> (zip/xml-zip parsed-xml) params)))

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
