Example
var toxml = require('../')
var from2Array = require('from2-array')
var input = require('../test/fixture.json')
var bounds = {
minlat: 38.89958342598271,
maxlat: 38.90385833966776,
minlon: -77.02514648437499,
maxlon: -77.01965332031249
}
from2Array.obj(input)
.pipe(toxml({bounds: bounds}))
.pipe(process.stdout)
output:

API
var toxml = require('obj2osm')
var stream = toxml(opts)
Where:
opts.root
- Root XML element (default:osm
, set tonull
to output XML with no root)opts.generator
- Generator attribute for the root element (default:obj2osm
)opts.bounds
- Optional bounds to include at start of XML, either{minlat: <Number>, maxlat: <Number>, minlon: <Number>, maxlon: <Number>}
or[[minLat, maxLat], [minLon, maxLon]]
Returns a transform object stream
that expects a stream of objects matching OSM JSON format as input and produces osm xml output or osmChange XML output if input objects have an action property set to one of: create|modify|delete
.
Node object format:
node.type
-'node'
node.id
- id stringnode.version
- version stringnode.lat
- latitude in degreesnode.lon
- longitude in degreesnode.tags
- Object of tag key-value pairs:{tagKey: 'tagValue', amenity: 'cafe'}
Way object format:
way.type
-'way'
way.id
- id stringway.version
- version stringway.nodes
- array of node IDsway.tags
- Object of tag key-value pairs
Relation object format:
relation.type
-relation.type
relation.id
- id stringrelation.version
- version stringrelation.members
- array of member objects:{type: 'node|way|relation', ref: 'id', role: 'role'}
relation.tags
- Object of tag key-value pairs
