xform-to-json v1.2.1
XForm to JSON converter
Converts XForm submissions from ODK Collect to json or geojson.
Usage
var xform2json = require('xform-to-json');
xform2json(xmlString, function(err, json) {
console.log(json);
})xform2json(xmlString, [options], callback)
ODK sends an xml file with a single root node, which is discarded.
By default the following metadata is created in the json output:
form.meta = {
instanceId: form.meta.instanceID || 'uuid:' + uuid.v1(),
instanceName: form.meta.instanceName || formKey,
formId: form.$.id,
version: form.$.version
};Where:
form.meta is the original meta data from the ODK xml submission
formKey is the name of the original xml root node
form.$.id and form.$.version are the two attributes on the root node from ODK xml.
options.geojson
When set to true will output geojson, using a geopoint field from the xml for the coordinates if present. If more than one geopoint field is present, the field is chosen arbitrarily unless options.locationField is set (see below). If no geopoint / location field is found then geojson geometry is null.
options.locationField
The fieldname to use for the geojson coordinates.
options.meta
Pass a hash of any metadata values to add to the form, e.g. meta.submissionTime.
