Filter the DataSource dataURL

[Cruonit]

Is there any way to filter the dataURL result in smatClient because i need to do it on the client side

typo3 response - JSON wrapped in the <div> tags (cant remove the tags and divs in typo3 so i need to filter it on the client side)

<?xml version="1.0" encoding="UTF-8"?>
	<!--

		BEGIN: Content of extension "api_typo3plugin", plugin "tx_typo3plugin_pi4"

	-->
	<div class="tx-apidashboard-pi4">
		[ { ...JSON... } ]
	</div>
	
	<!-- END: Content of extension "api_typo3plugin", plugin "tx_typo3plugin_pi4" -->

so i need to remove the comments and get the JSON ([ { ...JSON... } ])


I wrote this code:

isc.DataSource.create({
        ID:"xx",
	dataFormat:"custom",  // not json /xml -must be custom !!
	dataURL:"http://mysite.com/source.json",
	transformResponse: function(dsResponse, dsRequest, data){
		var test = dsResponse.data;

                // get only JSON from, the response
		var atpos = test.indexOf("[");
                var atpos2 = test.indexOf("]");
		
		if (atpos > -1) {
			test = test.substring(atpos,atpos2+1);
		}

	         dsResponse.data =test;
                 data =test;

                this.dataFormat="json";                                                        //set dataformat back to json
                dsResponse.data =   JSON.parse(dsResponse.data);

                return dsResponse;
         }

ok i filter out the string at the beginning of the Response but can't transform it back to json :|

it returns something but it's not correcly formated - the Loading data... disapears but the grid is empty (how to debug it ???)


(when i call the json source file without the comments and divs(remove it manually) with dataFormat: "json" - it works )


source json:

[ {"nmr":"022242069","nmr2":"122638958","price":"0.06","code":null,"time":"01.01.2011 14:08:17","duration":"18"},{"nmr":"062244233","nmr2":"112638958","price":"0.04","code":null,"time":"01.01.2011 21:01:53","duration":"14"} ]

lol it works :D

	transformResponse: function(dsResponse, dsRequest, data){
		var test = dsResponse.data;
		var atpos = test.indexOf("[");

		if (atpos > -1) {
			test = test.substring(atpos);
		}
		
		this.dataFormat="json";
		
		dsResponse.data = JSON.parse(test);
		
		data = test;
		dsResponse.totalRows =dsResponse.data.length;
		
		return this.Super("transformResponse", [dsResponse, dsRequest, data] );
	},

just added the
dsResponse.totalRows =dsResponse.data.length;
