Question

Can't get value from xml doc

I have a web service that is returning the following xml data.

I am trying to parse out 2192.25 but can't seem to get it to work. I have ried the following.

function constructAndSend(){
xhr.open("GET","https://www.mysecuredserver.com/webservices/pimswareservice.asmx/GetGatewayRevenue?freq=" + frequency);
xhr.send(null);
}

buttonRefresh.addEventListener('click', function(e)
{
lblBBIndex.text = 'You clicked index = ' + frequency;
constructAndSend();
});

xhr.onload = function()
{

xmlDoc = this.responseXML;

    try{
    xmlDoc.getElementsByTagName("string")[0].childNodes[0].nodeValue;
     var xmlAmount = xmlDoc.getElementsByTagName("document")[0].nodValue;

} catch(err) {

    var e = Titanium.UI.createAlertDialog();
      e.setTitle("Error");
    e.setMessage(err);
    e.show();
}

};

bb1.addEventListener('click', function(e)
{
frequency = e.index;
});

any suggestions? I am just trying to pull out the value and place it into a label.

Thanks in advance!!

Answer 1

Hi Chad,

This is the structure I use, it seems to work OK:

var itemList = response.documentElement.getElementsByTagName('item');
for (var c=0;c < itemList.length;c++){
myGuid = itemList.item(c).getElementsByTagName("guid").item(0).text;
};

cheers,
Chris

Answer 2

My XML output:

<result>
   <user>
         <fbid>1321613213215</fbid>
         <name>Jeff</name>
   </user>
</result>

Parsing is as follows:

    if(statusCode == 200)
    {
        Ti.API.info('>>> got the contacts xml! ... ');
        var xml = GETRequest.responseXML;
        Titanium.API.log("info","Response: "+xml);
        var result = xml.documentElement.getElementsByTagName("result");
        var itemList = xml.documentElement.getElementsByTagName("user");
        Ti.API.info('got item list');
        var cdata = [];

        //var id_text = $(this).attr('id');
        var fbid_text = itemList.item(0).getElementsByTagName("fb_ID").item(0).text;
        var name_text = itemList.item(0).getElementsByTagName("name").item(0).text;

    }

Chris,

Thanks for the response. When you refer to 'item', is this a name of an xml node or does it just mean an item of the tree? I am assuming that "guid" is the name of an xml node. I updated my code to follow what you send and I am now getting the following error.

"Result of expression 'itemLIst' [null] is not an object."

Any ideas?
