Example 1 with Node

use of org.kxml2.kdom.Node in project javarosa by opendatakit.

the class XFormParser method loadInstanceData.

// can fetch QuestionDefs bound to the given node, as the QuestionDef reference is needed to properly represent answers
// to select questions. obviously, we want to fix this.
