View Full Version : Populate XMLStore from a generated XmlString?

27 Aug 2010, 12:34 PM
Is it possible to load data into an XML Store from an xml string or object generated on the fly?

MemoryProxy seems to be the direction I want to head I think, can anyone give me some pointers using it if it can do what i'd like it to do?

Ext.data.XmlStore insert JSON object into store
reader of XmlStore (Ext.data.XmlReader), convert Xml document to Json Object

if you create your XML code on "fly", I suppose that you have a string variable like

var datas = '<?xml version="1.0" encoding="UTF-8"?><items><results>2</results><row><id>1</id><name>foo</name></row><row><id>2</id><name>foo2</name></row></items>';

but a string is not an Xml document
so, your first operation must be to convert string To Xml document

Answer gived by condor into another post (http://www.sencha.com/forum/showthread.php?54631-Can-XMLreader-read-XML-String&p=260298)

var xmlData = '<users total="1">' +
'<user><firstname>Jack<firstname><lastname>Jobs</lastname><phone>1234567890</phone></user>' +
'<user><firstname>Jenn<firstname><lastname>Syms</lastname><phone>4561230789</phone></user>' +

var doc;
doc = new ActiveXObject("Microsoft.XMLDOM");
doc.async = "false";
doc = new DOMParser().parseFromString(xmlData,"text/xml");

var xmlReader = new Ext.data.XmlReader({
record: 'user',
id: 'firstname',
totalRecords: '@total',
fields: ['firstname', 'lastname', 'phone']
var store = new Ext.data.Store({
reader: xmlReader,
data: doc
