Вы можете легко решать задачи на основе дерева, используя библиотеку Tupelo Forest.Вы можете посмотреть видео-введение из прошлогоднего Clojure Conj здесь .
Для вашей проблемы я подхожу к этому следующим образом.Сначала данные:
(dotest
(let [data-enlive
{:tag :root
:attrs nil
:content
[{:tag :SoapObject, :attrs nil,
:content
[{:tag :ObjectData, :attrs nil,
:content [{:tag :FieldName, :attrs nil, :content ["ID"]}
{:tag :FieldValue, :attrs nil, :content ["8d8edbb6-cb0f-11e8-a8d5-f2801f1b9fd1"]}]}
{:tag :ObjectData, :attrs nil,
:content [{:tag :FieldName, :attrs nil, :content ["Attribute_1"]}
{:tag :FieldValue, :attrs nil, :content ["Value_1a"]}]}
{:tag :ObjectData, :attrs nil,
:content [{:tag :FieldName, :attrs nil, :content ["Attribute_2"]}
{:tag :FieldValue, :attrs nil, :content ["Value_2a"]}]}]}
{:tag :SoapObject, :attrs nil,
:content
[{:tag :ObjectData, :attrs nil,
:content [{:tag :FieldName, :attrs nil, :content ["ID"]}
{:tag :FieldValue, :attrs nil, :content ["90e39036-cb0f-11e8-a8d5-f2801f1b9fd1"]}]}
{:tag :ObjectData, :attrs nil,
:content [{:tag :FieldName, :attrs nil, :content ["Attribute_1"]}
{:tag :FieldValue, :attrs nil, :content ["Value_1b"]}]}
{:tag :ObjectData, :attrs nil,
:content [{:tag :FieldName, :attrs nil, :content ["Attribute_2"]}
{:tag :FieldValue, :attrs nil, :content ["Value_2b"]}]}]}]}]
, а затем код
(with-debug-hid
(with-forest (new-forest)
(let [root-hid (add-tree-enlive data-enlive)
soapobj-hids (find-hids root-hid [:root :SoapObject])
objdata->map (fn [objdata-hid]
(let [fieldname-node (hid->node (find-hid objdata-hid [:ObjectData :FieldName]))
fieldvalue-node (hid->node (find-hid objdata-hid [:ObjectData :FieldValue]))]
{ (grab :value fieldname-node) (grab :value fieldvalue-node) }))
soapobj->map (fn [soapobj-hid]
(apply glue
(for [objdata-hid (hid->kids soapobj-hid)]
(objdata->map objdata-hid))))
results (mapv soapobj->map soapobj-hids)]
с промежуточными результатами:
(is= (hid->bush root-hid)
[{:tag :root}
[{:tag :SoapObject}
[{:tag :ObjectData}
[{:tag :FieldName, :value "ID"}]
[{:tag :FieldValue, :value "8d8edbb6-cb0f-11e8-a8d5-f2801f1b9fd1"}]]
[{:tag :ObjectData}
[{:tag :FieldName, :value "Attribute_1"}]
[{:tag :FieldValue, :value "Value_1a"}]]
[{:tag :ObjectData}
[{:tag :FieldName, :value "Attribute_2"}]
[{:tag :FieldValue, :value "Value_2a"}]]]
[{:tag :SoapObject}
[{:tag :ObjectData}
[{:tag :FieldName, :value "ID"}]
[{:tag :FieldValue, :value "90e39036-cb0f-11e8-a8d5-f2801f1b9fd1"}]]
[{:tag :ObjectData}
[{:tag :FieldName, :value "Attribute_1"}]
[{:tag :FieldValue, :value "Value_1b"}]]
[{:tag :ObjectData}
[{:tag :FieldName, :value "Attribute_2"}]
[{:tag :FieldValue, :value "Value_2b"}]]]])
(is= soapobj-hids [:0009 :0013])
и окончательными результатами:
(is= results
[{"ID" "8d8edbb6-cb0f-11e8-a8d5-f2801f1b9fd1",
"Attribute_1" "Value_1a",
"Attribute_2" "Value_2a"}
{"ID" "90e39036-cb0f-11e8-a8d5-f2801f1b9fd1",
"Attribute_1" "Value_1b",
"Attribute_2" "Value_2b"}]))))))
