I have called an ajax function that gather data from an xml file formatted like this
<?xml version="1.0" encoding="utf-8"?>
<values>
<value date="2015-07-12">37.170</value>
<value date="2015-07-13">7.190</value>
<value date="2015-07-12">37.170</value>
<value date="2015-07-12">3.210</value>
<value date="2015-07-12">37.20</value>
</values>
When I get the response from the console it says
not well-formed :1:80
Not sure what this means since when I use xml validator they all tell me that there are no errors. Any help would be awesome to have.
var data = [];
$.ajax({
url: 'test.xml', // name of file you want to parse
dataType: "xml", // type of file you are trying to read
success: parse, // name of the function to call upon success
async: false,
error: function(xhr, status, error) {
alert(xhr.responseText);
console.log("readyState: " + xhr.readyState);
console.log("responseText: "+ xhr.responseText);
console.log("status: " + xhr.status);
console.log("text status: " + textStatus);
console.log("error: " + err);
}
});
function parse(xml) {
var items = jQuery(xml).find("values");
var data = [];
var values = $(items).text();
$(document).find("Values").each(function () {
$(this).find("value").each(function () { data.push($this.text);});
});
console.log(data.length);
}
Not sure ethier how to get all of the values into the array.
You may be trying to parse it twice, per the documentation:
The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).
Thus I'm imagining that this is what you are looking for:
function parse(xml) {
//var items = jQuery(xml).find("values");
var items = xml.find("values");
var data = [];
var values = $(items).text();
$(document).find("Values").each(function () {
$(this).find("value").each(function () { data.push($this.text);});
});
console.log(data.length);
}
EDIT!
Fiddle is updated.

No need to parse data with parseXML.
Erik Phillips is probably right about the double parsing. Anyways, this should work.
Note the use of ECHO in fiddle..... just to simulate a local xml-file.
$.ajax({
url: 'test.xml', // name of file you want to parse
dataType: "xml", // type of file you are trying to read
success: parse, // name of the function to call upon success
async: false,
error: function(xhr, status, error) {
alert("error");
}
});
function parse(xmldata) {
$(xmldata).find("value").each(function(){
alert($(this).text());
});
}
For anybody else having a problem parsing non-well-formed (self-closing tags) xml in IE, $(xmlthing).find('nodename').each... works, whereas IE will parse $(xmlthing).children('nodename').each... (which is fine in FF and Chrome), as nested.
That is:
<thing />
<thing />
<thing />
will be 3 things in FF/Chrome, but one in IE if you use $(node).children(thing)
$(node).find(thing) will give you 3 things in all browsers. Thanks #Steen

I am a beginner with JavaScript and I am facing some issues with parsing JSON and display the data I want to.
When I run the URL manualy in browser I get a correct result back.
The JavaScript code looks like this:
request = "URL"
function CallRestService(request, callback) {
$.ajax({
url: request,
dataType: "jsonp",
jsonp: "jsonp",
success: function (r) {
callback(r);
var results = data.resourceSets;
console.log(r.message);
alert(r.statusText);
},
error: function (e) {
alert("Error" + JSON.stringify(e));
console.log("Error" + e.message);
}
});
}
When I run this code I get no error in the console but I still get an alert via the error function: "status":200,"statusText":"OK"
Why do I get this?
And thats why I cannot get my data displayed, what I am doing wrong?
EDIT
so I was able to make a working code out of it, but I still get messages from SUCCESS and ERROR at the same time and I also get my data back?!
<script>
var request = "URL";
function CallRestService(request, callback) {
$.ajax({
url: request,
dataType: "jsonp",
jsonp: "jsonp",
success: function (r) {
callback(r);
console.log("working" + r.message);
alert(r.statusText);
},
error: function (e) {
alert("Error" + e.message + JSON.stringify(e));
console.log("message: " + e.message);
console.log("readyState: " + e.readyState);
console.log("responseText: "+ e.responseText);
console.log("status: " + e.status);
}
});
}
CallRestService(request, GeocodeCallback);
function GeocodeCallback(results) {
console.log(results.resourceSets[0].resources[0].travelDurationTraffic);
document.getElementById("sec").innerHTML=Math.round((parseFloat(results.resourceSets[0].resources[0].travelDurationTraffic) / 60));
}
</script>
Assuming that you put an actually URL into the request parameter this looks fine. A 200 status means it was successful and this likely called the console from your success function. I know you said you removed it to be sure, but the page could of been cached. If you take a look at the network request you will likely see that it was successful as well. Ifs possible that an error in your success function is occurring and triggering the error function. Have you tried adding break points inside of the two functions?
Here is a blog post that shows how to access the Bing Maps REST services using jQuery and other frameworks: https://blogs.bing.com/maps/2015/03/05/accessing-the-bing-maps-rest-services-from-various-javascript-frameworks/ It looks like your code is very similar.
I have this URL, that I supposedly should receive an XML from. So far I have this:
function GetLocationList(searchString)
{
$.ajax({
url: "http://konkurrence.rejseplanen.dk/bin/rest.exe/location?input=" + searchString,
type: "GET",
dataType: "html",
success: function(data) {
//Use received data here.
alert("test");
}
});
Tried to debug with firebug, but it doesn't go into the success method.
Though, in DreamWeaver it is able to post a simple alert, which is inside the success method.
I tried writing xml as dataType, but it doesn't work (in DreamWeaver) when I write alert(data).
But it shows an alert with the entire XML, when I write html as dataType.
How do I get the XML correctly, and how do I parse and for example get the "StopLocation" element?
Try to add an Error function as well.
See enter link description here
This will give you all the informations you need to debug your code with Firefox.
$.ajax({
url: "http://konkurrence.rejseplanen.dk/bin/rest.exe/location?input=" + searchString,
type: "GET",
dataType: "html",
success: function(data) {
//Use received data here.
alert("test");
},
error: function(jqXHR, textStatus, errorThrown ){
// debug here
}
});
you need to parse it first, and then you can search for the attributes. like this.
success: function(data) {
var xml = $.parseXML(data)
$(xml).find('StopLocation').each(function()
{
var name = $(this).attr('name');
alert(name);
}
);
this will give you the name of each StopLocation.
hope this helps, you can use the same method for all other attributes in the document also.
I've been trying to create a small page and all it does is update some values from a source document. The page loads fine, but I don't get the results from the requested source. The .fail function runs, but the textStatus and errorThrown values don't appear in the alert() window that pops up.
I'm very new to javascript and jquery. I'm trying to bash this together with pieces found from the web to figure it out but nothing seems to be working. Mainly, it's the response I think I'm falling down on...
Anyway, here's the code:
<html>
<head>
<title></title>
<script type="text/javascript" src="~/Scripts/jquery-1.9.1.js"></script>
<script type="text/javascript">
function update() {
$.ajax({
type: "GET",
url: "http://192.168.2.86:15890/linearlist.xml",
dataType: "xml"
}).done(function (res) {
//alert(res);
}).fail(function (jqXHR, textStatus, errorThrown) {
alert("AJAX call failed: " + textStatus + ", " + errorThrown);
});
}
function GetData() {
update();
setTimeout(function () {
GetData();
}, 50);
}
});
</script>
</head>
<body>
<script type="text/javascript">
GetData();
</script>
<div class="result"> result div</div>
</body>
</html>
UPDATE:
I've update my code re: #Ian's answer. It's still not working, sadly. I'm not getting the textStatus or errorThrown results either. I've tried debugging with Internet Explorer through VS2012 but it's not getting me far. If I put the URL into a webpage, I can view the XML document.
$.get does not accept one parameter as an object literal; it accepts several: http://api.jquery.com/jQuery.get/#jQuery-get1
You might be thinking of the $.ajax syntax: http://api.jquery.com/jQuery.ajax/
Anyways, call it like:
$.get("http://192.168.2.86:15890//onair.status.xml", {}, function (res) {
var xml;
var tmp;
if (typeof res == "string") {
tmp = "<root>" + res + "</root>";
xml = new ActiveXObject("Microsoft.XMLDOM");
xml.async = false;
xml.loadXML(res);
} else {
xml = res;
}
alert("Success!");
}, "text");
Or use $.ajax:
$.ajax({
type: "GET",
url: "http://192.168.2.86:15890//onair.status.xml",
dataType: "text"
}).done(function (res) {
// Your `success` code
}).fail(function (jqXHR, textStatus, errorThrown) {
alert("AJAX call failed: " + textStatus + ", " + errorThrown);
});
Using the fail method, you can see that an error occurred and some details why.
Depending on what/where http://192.168.2.86:15890 is, you may not be able to make AJAX calls due to the same origin policy - https://developer.mozilla.org/en-US/docs/JavaScript/Same_origin_policy_for_JavaScript
I know you have some logic in your success callback, but I'm pretty sure if you specify the dataType as "text", the res variable will always be a string. So your if/else shouldn't really do much - the else should never execute. Either way, if you're expecting XML, it's probably easier to just specify the dataType as "xml".
I am trying to parse an xml response using jQuery and just output an element the a page but i am unsuccessful in this.
Below is the code that I am using for the response & parsing of it.
$.ajax({
url: UCMDBServiceUrl,
type: "POST",
dataType: "xml",
data: soapMessage,
success: UCMDBData,
crossDomain: true,
contentType: "text/xml; charset=\"utf-8\""
});
alert("Sent2");
return false;
}
function UCMDBData(xmlHttpRequest, status, msg)
{
alert("Came back1");
$(xmlHttpRequest.responseXML).find('tns:CIs').each(function()
{
alert("Came back2");
$(this).find("ns0:CI").each(function()
{
alert("Came back3");
$("#output").append($(this).find("ns0:ID").text());
});
});
}
I am receiving alerts for "Came back1" but it doesnt appear to be going any further. Below is the XML Response that I am trying to parse using my above jquery code. The text that I am ultimately trying to return out of the response is in this element
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Header />
<soapenv:Body>

</tns:getFilteredCIsByTypeResponse>
</soapenv:Body>
</soapenv:Envelope>
So my question is that how do I properly parse the data? I believe the code syntax is correct but I am not getting the expected returned results. I would appreciate any help, thanks.
EDIT
I have modified my code to the following like the suggestion, but still no luck:
$.ajax({
url: UCMDBServiceUrl,
type: "POST",
dataType: "xml",
data: soapMessage,
success: UCMDBData,
crossDomain: true,
contentType: "text/xml;"
});
alert("Sent2");
return false;
}
function UCMDBData(data, textStatus, jqXHR) {
alert("Came back1");
$(data).find('tns:CIs').each(function () {
alert("Came back2");
$(this).find("ns0:CI").each(function () {
alert("Came back3");
$("#output").append($(this).find("ns0:ID").text());
document.AppServerForm.outputtext.value = document.AppServerForm.outputtext.value + "http://localhost:8080/ucmdb/cms/directAppletLogin.do?objectId=" + $(this).find('ns0:ID').text() +"&infopane=VISIBLE&navigation=true&cmd=ShowRelatedCIs&interfaceVersion=8.0.0&ApplicationMode=ITU&customerID=1&userName=admin&userPassword=admin";
});
});
}
When I execute the only alert message i receive back is "Came back1" which means that the code is still not going through the xml properly with jquery. Any other suggestions?
The namespace-scoped names need to be handled a little differently. According to this answer:
jQuery XML parsing with namespaces
you would need to use an attribute selector [#nodeName=tns:CIs] instead.
You may need to drop the "#" for jQuery versions later than 1.3. Another suggestion is to escape the colon: .find('tns\:CIs'), which is hacky because it conflates the syntactic prefix with the semantic namespace (the uri). So if the prefix changed this method would break. A more correct answer will recognize the mapping of prefix to namespace uri. The jquery-xmlns plugin for namespace-aware selectors looks promising in that respect.
Your jQuery success function is of the wrong form. It needs to be of the form
function UCMDBData(data, textStatus, jqXHR) {
alert("Came back1");
$(data).find('tns:CIs').each(function () {
alert("Came back2");
$(this).find("ns0:CI").each(function () {
alert("Came back3");
$("#output").append($(this).find("ns0:ID").text());
});
});
}
In addition, in your $.ajax function, change the contentType line to be contentType: "text/xml" instead of what you have before (assuming that you're sending XML to the server).
See the jQuery.ajax() documentation for more information.
Based on your comment, why do something crazy with jQuery? Just use javascript itself!
var open = '<ns0:ID>';
var close = '</ns0:ID>';
var start = obj.indexOf(open) + open.length;
var end = obj.indexOf(close);
var result = obj.slice(start, end);
Here's a jsfiddle that shows it in action.
Probably the right syntax would be
success: function(xml) {
$(xml).find('tns:CIs').each(function() {
......
I don't know why this is happening since there are other functions in this page that use also getJSON and they do work. I have the following JavaScript Code
function openSOPNotesDialog() {
var url = '<%: Url.Action("GetSOPNote", "SalesOrder") %>';
var id = <%: Model.SodID %>;
$.getJSON(url, { sodId : id }, function(data) {
alert("data: " + data);
$("#hidSOPSODId").val(data.SodID);
$("#hidNoteId").val(data.NoteID);
$("#txtSOPNotes").val(data.Description);
$("#sopNotesDialog").dialog("open");
});
}
and then I have this method on the SalesOrderController class
public JsonResult GetSOPNote(int sodId)
{
var service = new SodSrv();
var note = service.GetSOPNotes(sodId);
return Json(note, JsonRequestBehavior.AllowGet);
}
However, the method is never called in the debugger and data is returned as null (which is what I'd expect). As I said before there are other calls in this page and they are also doing GET requests so I don't know what may be the cause.
Sounds like the browser is pulling the data from the cache since it is a get request. Make sure to set no cache headers on the server if it is not meant to be cached.
Try adding an error handler to try to track down what the issue is:
$.ajax({
dataType: 'json',
url: url,
data: { sodId : id },
success: function(data) {
alert("data: " + data);
$("#hidSOPSODId").val(data.SodID);
$("#hidNoteId").val(data.NoteID);
$("#txtSOPNotes").val(data.Description);
$("#sopNotesDialog").dialog("open");
},
error: function(jqXHR, textStatus, errorThrown) {
alert("oops: " + textStatus + ": " + jqXHR.responseText);
}
});
I suspect that the reason is that getJSON uses get method and controllers normally allowed to accept only post methods. It's ease to check using any browser firebug for example.
