How to pass an xml request to a grid

Hi,

I'm currently trying to figure out how to parse an xml result to the AW.grid.

I've got a search form enabling users to query a DB with (name, category,provenance,region variables) trigged by an onClick="query_texis();".

Once the values of the form are checked they are parsed to the server-side (vortex-texis) script that queries the database. All goes fine! Texis has a handy output option enabling the request to be output in xml.
<SQL output=xml "SELECT * FROM blablabal WHERE name like ...></SQL>

When I check the xmlHttp.responseTEXT i'm getting as planed an xml response. The trick I can't figure out is how to parse this variable (the xml string) to the AW.table and then to the grid functions.

Anyone have an idea?


The result of the server-side query; (var result = xmlHttp.responseTEXT;)

<? xml version="1.0" encoding="UTF-8" ?>
<results>
<result>
<NAME>Council of Europe </NAME>
<FURL>http://www.coe.int/defaulten.asp</FURL>
<CATEGORY>Prime Sources</CATEGORY>
<SUBCATEGORY>European Organizations</SUBCATEGORY>
<PROVENANCE></PROVENANCE>
<REGION></REGION>
</result>
<result>
<NAME>Asia Women's Human Rights Council</NAME>
<FURL>http://www.awhrc.org/index.htm</FURL>
<CATEGORY>Subject-Based Sources</CATEGORY>
<SUBCATEGORY>Women</SUBCATEGORY>
<PROVENANCE></PROVENANCE>
<REGION>Asia</REGION>
</result>
</results>

The scripts;
<script>
var xmlHttp = false; //check wich browser the user is using
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e) {
try {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e2) {
xmlHttp = false;
}
}
if (!xmlHttp && typeof XMLHttpRequest != 'undefined') {
xmlHttp = new XMLHttpRequest();
}

function query_texis(){
var name = document.getElementById('NAME').value;
var category = document.getElementById('CATEGORY').value;
var provenance = document.getElementById('PROVENANCE').value;
var region = document.getElementById('REGION').value;
var url = "xml1?name=" + escape(name) + "&category=" + escape (category) + "&provenance=" + escape(provenance) + "&region=" + escape(region);
// Open a connection to the server
xmlHttp.open("POST", url, true);
// Setup a function for the server to run when it's done
xmlHttp.onreadystatechange = updatePage;
// Send the request
xmlHttp.send(null);
}

function updatePage(){
if(xmlHttp.readystate == 4){
var result = xmlHttp.responseTEXT;
alert(result);

var table = new AW.XML.Table; //can't figure out this bit
//table.setURL(result); //tried using getXML(result)
table.setAsync(false);
table.request();

var obj = new AW.UI.Grid;
obj.setId("grid");
obj.setHeaderText(["URL Name","URL","Category","Subcategory","Country","Region"]);
obj.setColumnCount(6);
obj.setCellData(table);
document.write(obj);
}
}
</script>

Check the examples that come with the Grid install.

Here is an example:

var itsTableZones = new AT.XML.Table;
itsTableZones.setURL(theURL);		
itsTableZones.setRows('/result/zones/zone');
itsTableZones.setColumns(['zoneid','zonename','servername','viewname','zonetype']);
itsTableZones.setAsync(false);
itsTableZones.request();

// Now itsTableZones contains the XML
// Then you can simply loop through the itsTableZones using getData
// And set the Grid values using setCellText

give a try to ths instead of using get data loop..

gridobj.setCellModel(table);

Correct and much simpler, but only if the Table is identical to the Grid.
