XML Parsing in Smartface
If you want to work with XML data, you can use the third party xml parser library.
Example library : https://github.com/NaturalIntelligence/fast-xml-parser​
Install library on Smartface :
(cd ~/workspace/scripts/node_modules && npm install fast-xml-parser)
 XML Parse Example :
var fastXmlParser = require('fast-xml-parser');
var xmlData = "<bookstore><book>" +
    "<title>Everyday Italian</title>" +
    "<author>Giada De Laurentiis</author>" +
    "<year>2005</year>" +
    "</book></bookstore>";
var JsonResult = fastXmlParser.parse(xmlData);
console.log("JSON Data : " + JSON.stringify(JsonResult))
​
​
// when a tag has attributes
var options = {
  attrPrefix: "@_",
  attrNodeName: false,
  textNodeName: "#text",
  ignoreNonTextNodeAttr: true,
  ignoreTextNodeAttr: true,
  ignoreNameSpace: true,
  ignoreRootElement: false,
  textNodeConversion: true,
  textAttrConversion: false,
  arrayMode: false
};
if (fastXmlParser.validate(xmlData) === true) { //optional
  JsonResult = fastXmlParser.parse(xmlData, options);
  console.log("JSON Data : " + JSON.stringify(JsonResult))
}
​
//Intermediate obj
var tObj = fastXmlParser.getTraversalObj(xmlData, options);
JsonResult = fastXmlParser.convertToJson(tObj);
console.log("JSON Data : " + JSON.stringify(JsonResult))
JSON Parsing in Smartface
var JsonResult = JSON.parse(data); // data is string.
console.log("JSON Data : " + JSON.stringify(JsonResult))
