Reading XML in id = "key" value = "value" format?

Question

How can I read XML in attribute format in ExtJS repository, where key / values ​​are listed on the same line as id / value? I am more familiar with the second format below.

  <? xml version = "1.0" encoding = "UTF-8"?>
 <XMLResponse>
     <data>
         <row>
             <column id = "title" value = "Star Wars" />
             <column id = "director" value = "Lucas" />
             <column id = "year" value = "1977" />
         </row>
         <row>
             <column id = "title" value = "Jaws" />
             <column id = "director" value = "Spielberg" />
             <column id = "year" value = "1975" />
         </row>
     </data>
 </XMLResponse>

A more traditional way of writing XML.

  <? xml version = "1.0" encoding = "UTF-8"?>
 <XMLResponse>
     <data>
         <row>
             <title> Star Wars </title>
             <director> Lucas </director>
             <year> 1977 </year>
         </row>
         <row>
             <title> Jaws </title>
             <director> Spielberg </director>
             <year> 1975 </year>
         </row>
     </data>
 </XMLResponse>

This is not well documented, but matching for your fields can be any expression accepted by Ext.dom.Query . Therefore, when you usually have a simple “title” mapping to select a child tag named “title”, you can include a more complex selector. In this case, you want to select the “value” attribute of the “column” tags, whose identification attributes correspond to the name of the field you are looking for, so in your model or repository you can define your fields as follows:

fields: [ { name: 'title', mapping: 'column[id=title]@value' }, { name: 'director', mapping: 'column[id=director]@value' }, { name: 'year', mapping: 'column[id=year]@value' } ],
