Thank you Tom! Exactly was I was looking for!
I will TRY to add some documentation to clojuredocs.org just so people won't be that afraid, this xml-functionality is a very sane way of doing it, it's just takes a while to get used to it (I'll check that it's refered to the correct namespace as well). I guess next step would be making a clojar avaliable, but I have no clue on how to do that yet. /Linus 2011/12/13 Tom Faulhaber <tomfaulha...@gmail.com> > Hi Linus, > > Zippers and their associated helpers are woefully undocumented, so I'm > not surprised you fell into the swamp. > > I think that the help you're looking for can be found in the > clojure.data contrib project (see https://github.com/clojure/data.zip > for the source and http://clojure.github.com/data.zip for the > autodoc). > > Using that, the xpathy thing you're looking for is something like > this: > > (ns play.xml-example > (:require [clojure.zip :as zip] > [clojure.data.zip :as zf] > [clojure.xml :as xml]) > (:use clojure.data.zip.xml)) > > (def mz (zip/xml-zip (xml/parse "dataabove.xml"))) > > (defn get-all-dimensions [] > (doseq [id (xml-> mz zf/descendants (attr= :id "2") zf/children :e > (attr :id))] > (println (apply str id)))) > > > Note that I had to make a couple of fixes to the above XML to make it > right. > > I hope that's useful! > > Tom > > On Dec 12, 7:06 am, Linus Ericsson <oscarlinuserics...@gmail.com> > wrote: > > Hello! > > > > What's the clever way to read the E-tags "thisone" and "andthis" in the > > XML-file below given I don't know their id on beforehand? > > > > <a> > > <b>bla bla</b> > > <b>bla bla</b> > > <c id="wanted"> > > <d id="1"> > > <e id="notthisone"/></d> > > <d id="2"> > > <e id="thisone"/> > > <e id="andthis"/></d> > > <d id="3"> > > <e id="not-intresting"></d> > > </a> > > > > My solution so far would be something like > > > > (def mz (zip/xml-zip (xml/parse "dataabove.xml"))) > > > > (defn get-all-dimensions [] > > (filter #(and (= "2" (:id %)) (= :e (:tag %))) (zip/children mz)))) > > > > but I'm looking for some descending solution > > > > (-> mz > > (zip/down a) > > (zip/down c :where (= :id "wanted")) > > (zip/down d :where (= :id 2)) > > zip/children) > > > > (an xpath-like solution would most awesome) > > > > According to it's own page Enlive is not very good for xml and I cannot > > figure out the way to dynamically walk with zippers (like "go into the > tag > > :d with id=...").
