I need to consume a SOAP web service which, naturally, sends its response in XML, since I'm developing a Appcelerator Titanium mobile app I would prefer the response in JSON. After looking online I converted the response using this Javascript code, it mostly worked but returned results such as the following:
{
"SOAP-ENV:Body" : {
"ns1:linkAppResponse" : {
"ns1:result" : {
#text : true;
};
"ns1:uuid" : {
#text : "a3dd915e-b4e4-43e0-a0e7-3c270e5e7aae";
};
};
};
}
Of course the colons and hashes in the caused problems so I adjusted the code to do a substring on the name and drop off anything before the ':', then a stringified the resulting JSON, removed all the hashes and parsed the JSON again. This is a bit messy for my liking but I end up with something usable.
Here is the xmlToJson code I'm using:
// Changes XML to JSON
function xmlToJson(xml) {
// Create the return object
var obj = {};
if (xml.nodeType == 1) {// element
// do attributes
if (xml.attributes.length > 0) {
obj["#attributes"] = {};
for (var j = 0; j < xml.attributes.length; j++) {
var attribute = xml.attributes.item(j);
obj["#attributes"][attribute.nodeName] = attribute.nodeValue;
}
}
} else if (xml.nodeType == 3) {// text
obj = xml.nodeValue;
}
// do children
if (xml.hasChildNodes()) {
for (var i = 0; i < xml.childNodes.length; i++) {
var item = xml.childNodes.item(i);
var nodeName = item.nodeName.substring(item.nodeName.indexOf(":") + 1);
if ( typeof (obj[nodeName]) == "undefined") {
obj[nodeName] = xmlToJson(item);
} else {
if ( typeof (obj[nodeName].push) == "undefined") {
var old = obj[nodeName];
obj[nodeName] = [];
obj[nodeName].push(old);
}
obj[nodeName].push(xmlToJson(item));
}
}
}
return obj;
};
module.exports = xmlToJson;
Which results in the following JSON:
{
Body : {
linkAppResponse : {
result : {
text : true;
};
uuid : {
text : "9022d249-ea8a-47a3-883c-0f4cfc9d6494";
};
};
};
}
While this returns a JSON object I can use, I would prefer to have the resulting JSON in the following form:
{
result : true;
uuid : "9022d249-ea8a-47a3-883c-0f4cfc9d6494";
};
Mostly so it's less verbose and I can simply call json.result in order check if the query was successful instead of json.Body.linkAppResponse.result.text
Any help is greatly appreciated.
Came up with a working solution, not any less dirty but it works and returns data in the format I want.
function soapResponseToJson(xml) {
var json = xmlToJson(xml).Body;
console.debug(json);
var response = {};
for (var outterKey in json) {
if (json.hasOwnProperty(outterKey)) {
temp = json[outterKey];
for (var innerKey in temp) {
if (temp.hasOwnProperty(innerKey)) {
response[innerKey] = temp[innerKey].text;
}
}
}
}
console.debug(response);
return response;
}
// Changes XML to JSON
function xmlToJson(xml) {
// Create the return object
var obj = {};
if (xml.nodeType == 1) {// element
// do attributes
if (xml.attributes.length > 0) {
obj["#attributes"] = {};
for (var j = 0; j < xml.attributes.length; j++) {
var attribute = xml.attributes.item(j);
obj["#attributes"][attribute.nodeName] = attribute.nodeValue;
}
}
} else if (xml.nodeType == 3) {// text
obj = xml.nodeValue;
}
// do children
if (xml.hasChildNodes()) {
for (var i = 0; i < xml.childNodes.length; i++) {
var item = xml.childNodes.item(i);
var nodeName = item.nodeName.substring(item.nodeName.indexOf(":") + 1).replace('#', '');
if ( typeof (obj[nodeName]) == "undefined") {
obj[nodeName] = xmlToJson(item);
} else {
if ( typeof (obj[nodeName].push) == "undefined") {
var old = obj[nodeName];
obj[nodeName] = [];
obj[nodeName].push(old);
}
obj[nodeName].push(xmlToJson(item));
}
}
}
return obj;
};
module.exports = soapResponseToJson;
console.debug(json):
{
linkAppResponse : {
result : {
text : true;
};
uuid : {
text : "e4f78c5f-1bc2-4b50-a749-19d733b9be3f";
};
};
}
console.debug(response):
{
result : true;
uuid : "e4f78c5f-1bc2-4b50-a749-19d733b9be3f";
}
I'm going to leave this question open for a while in case someone comes up with a better solution.
I feel like this is a fairly ugly solution (hope it doesn't offend you :) ).
Why don't you marshal the xml to an object and then use gson or jackson to map to json.
I don't know what framework you use, in spring for example, you can use jaxb2 to marshal and jackson or gson to transform your object to json.

This can actually be achieved pretty simply. All you need to do is give your table an ID to be able to select it, and have a loop in the tabletop callback:
function gotData(data) {
const table = document.getElementById("table1-id").tBodies[0];
for (const player of data) {
const row = table.insertRow(-1); // index -1 inserts at bottom
const keys = Object.keys(player);
for (let i = 0; i < keys.length; i++) {
const c = row.insertCell(i);
c.appendChild(document.createTextNode(player[keys[i]]));
}
}
}

Input XML :
<Message><id value="123"></id><type value="Test"></type></Message>
Actual Output:
{"id":{"_value":"123"},"type":{"_value":"Test"}}
Expected Output:
{"id":"123","type":"Test"}
Guide me where am missing the part to get the expected output.

do you think if you do this way will work for you?
put your actual output from that parser to this function:
function convertToExpectedOutput(obj){
var result = {}
for (var i in obj){
if (i == "_value")
return obj[i];
else
result[i] = convertToExpectedOutput(obj[i])
}
return result;
}
convertToExpectedOutput(actualOutput)
So, for your array, hange the convertToExpectedOutput to this way and it will give the expected result:
function convertToExpectedOutput(obj){
var result = {}
for (var i in obj){
if (i == "_value")
return obj[i];
else
if (Array.isArray(obj[i])){
result[i] = [];
arr = obj[i]
for (var j in arr)
result[i].push(convertToExpectedOutput(arr[j]))
}
else
result[i] = convertToExpectedOutput(obj[i])
}
return result;
}
When parsing documents using the excellent libxmljs library in Node.js, I stumbled across a case where a lot of nested elements were found, and the only thing I had to do was create a JS object from it.
Here is what the code looks like :
if (node.type() == 'element') {
switch(node.name()) {
case 'element1': {
myObject.element1 = {}
for (var i = 0; i < node.childNodes().length; i++) {
if(node.type() == 'element') {
switch(node.name()) {
case 'element2': {
myObject.element1.element2 = node.text()
...
}}}}}}}}
/* didn't count the number of closing brackets, but you get the idea ^_^ */
Is there a faster or built-in way to do such things, create an object from an XML string (or part of it) using libxmlJS ?
Note that, if it helps, the parsed XML must be validated against a XTD schema (which can really easily be done using this library)
Thanks
Here is some non-working code that can be found on this article :
function XML2jsobj(node) {
var data = {};
// append a value
function Add(name, value) {
if (data[name]) {
if (data[name].constructor != Array) {
data[name] = [data[name]];
}
data[name][data[name].length] = value;
}
else {
data[name] = value;
}
};
// element attributes
var c, cn;
for (c = 0; cn = node.attributes[c]; c++) {
Add(cn.name, cn.value);
}
// child elements
for (c = 0; cn = node.childNodes[c]; c++) {
if (cn.nodeType == 1) {
if (cn.childNodes.length == 1 && cn.firstChild.nodeType == 3) {
// text value
Add(cn.nodeName, cn.firstChild.nodeValue);
}
else {
// sub-object
Add(cn.nodeName, XML2jsobj(cn));
}
}
}
return data;
}
From that code, I could build something that seems to work with the latest libxmljs release, here it is :
function XML2jsobj(node) {
var data = {};
// append a value
function Add(name, value) {
if (data[name]) {
if (data[name].constructor != Array) {
data[name] = [data[name]];
}
data[name][data[name].length] = value;
}
else {
data[name] = value;
}
};
for (var c = 0; c < node.attrs().length; c++) {
var cn = node.attrs()[c];
Add(cn.name, cn.value);
}
// child elements
for (var c = 0; c < node.childNodes().length; c++) {
var cn = node.childNodes()[c];
if (cn.type() == 'element') {
if (cn.childNodes().length == 1 && cn.childNodes()[0].type() == 'text') {
// text value
Add(cn.name(), cn.childNodes()[0].text());
}
else {
// sub-object
Add(cn.name(), XML2jsobj(cn));
}
}
}
return data;
}
I hope this will have helped someone.
This function match sets an attribute (collapsed) to true or false depending on
the value of a string :
function match(children) {
var data = $scope.treeData
for (var i = 0; i < data.length; i++) {
var s = data[i]
for (var i2 = 0; i2 < s.children.length; i2++) {
var s2 = s.children[i2]
for (var i3 = 0; i3 < s2.children.length; i3++) {
for (var i4 = 0; i4 < s2.children[i3].children.length; i4++) {
var text = "";
if ($scope.searchText == undefined) {
text = ""
} else {
text = $scope.searchText
}
if (s2.children[i3].children[i4].label
.toLowerCase() === text.toLowerCase()) {
s2.children[i3].collapsed = false
}
}
}
}
}
}
Excluding the bad use of variable names i3,i2 etc is there a cleaner method ?
As the inner most loop requires access to the outer loop can recursion still be used ?
Update :
Data structure :
[{"label":"test","collapsed":false,"children":[{"label":"test","collapsed":false,"children":[],"$$hashKey":"002"}],"$$hashKey":"001"}]
Update 2 :
Using a recursive function but the string 'test' is not being matched :
http://jsfiddle.net/U3pVM/19196/
fiddle src :
<div ng-app>
<h2>Todo</h2>
<div ng-controller="TodoCtrl">
</div>
</div>
function TodoCtrl($scope) {
var json = [{"label":"test","collapsed":false,"children":[{"label":"test","collapsed":false,"children":[],"$$hashKey":"002"}],"$$hashKey":"001"}]
var searchText = 'test'
function match(node, searchText){
angular.forEach(node.children, function(idx, child){
node.collapsed = child.label.toLowerCase === searchText.toLowerCase
console.log(node.collapsed)
if(child.children.length > 0){
match(child, searchText);
}
});
}
match(json, searchText);
}
Please try this :
function match2(obj) {
if (obj.children) {
for (var i = 0; i < obj.children.length; i++) {
match2(obj.children[i]);
}
}
else {
var text = $scope.searchText ? $scope.searchText : "";
if (obj.label
.toLowerCase() === text.toLowerCase()) {
obj.collapsed = false
}
}
Your JSFiddle is very nearly there. I made a couple of changes for this working JSFiddle.
First, you were passing an array into match and not an object. I changed your json variable to be json instead by removing the outer [], but you could also have fixed this by passing in json[0].
The other change was that you had the two parameters, child and idx, were the wrong way round.
function match(node, searchText){
angular.forEach(node.children, function(child, idx){
node.collapsed = child.label.toLowerCase === searchText.toLowerCase
console.log(node.collapsed)
if(child.children.length > 0){
match(child, searchText);
}
});
}
Here's another way of doing it, using some:
function match (node, searchText) {
node.collapsed = node.children.some(function(child) {
return child.label.toLowerCase === searchText.toLowerCase;
});
angular.forEach(node.children, function(child, idx){
match(child, searchText);
})
}
I think something like this may work for you. I don't know anything about angular there might be something there that would make it easier.
var searchText = ($scope.searchText == undefined) ? "": $scope.searchText;
match($scope.treeData, searchText);
function match(node, searchText){
$.each(node.children, function(idx, child){
node.collapsed = child.label.toLowerCase === searchText.toLowerCase
if(child.children.length > 0){
match(child, searchText);
}
});
}
I have an object output from below code how to set the index start from 0 in js?
Object
3: Object
id: 34
type: 0
var obj = {};
var edited = false;
for (var i = 0; i < $(".list").length; i++) {
var data_id = parseInt($(".list").eq(i).attr('data-id'));
var data_type = parseInt($(".list").eq(i).attr('data-type'));
if ((data_type != 0)) {
edited = true;
} else {
edited = false;
}
if (edited == true) {
obj[i] = {};
obj[i]['id'] = data_id;
obj[i]['type'] = data_type;
}
}
console.log(obj);
Needs more jQuery ?
var arr = $(".list").filter(function() {
return $(this).data('type') != 0;
}).map(function() {
return { id : $(this).data('id'), type : $(this).data('type') };
}).get();
FIDDLE
Actually if you want to start in 0, use another variable and not "i" (which I think is 3 when you use it as index).
var obj = {};
var edited = false;
var obj_idx = 0;
for (var i = 0; i < $(".list").length; i++) {
var data_id = parseInt($(".list").eq(i).attr('data-id'));
var data_type = parseInt($(".list").eq(i).attr('data-type'));
if ((data_type != 0)) {
edited = true;
} else {
edited = false;
}
if (edited == true) {
obj[obj_idx] = {};
obj[obj_idx]['id'] = data_id;
obj[obj_idx]['type'] = data_type;
obj_idx += 1;
}
}
console.log(obj);
I think this time obj will be something like:
Object
0: Object
id: 34
type: 0
you could fake object as array by Array.prototype.push.call, in that way you could also gain the side effect: obj.length. it's kinda ninja and elegant :]
var obj = {};
var edited = false;
for (var i = 0; i < $(".list").length; i++) {
var data_id = parseInt($(".list").eq(i).attr('data-id'));
var data_type = parseInt($(".list").eq(i).attr('data-type'));
if ((data_type != 0)) {
edited = true;
} else {
edited = false;
}
if (edited == true) {
Array.prototype.push.call(obj, {id: data_id, type: data_type});
}
}
I am going to give a very simple and readable example. Say you've got an object with the following structure:
Object
0: Object
key: 'some-key'
value: 'some-value'
1: Object
...
Then you might want to delete an entry from it and reindex the whole thing, this is how I do it:
// obj is Object from above
const reIndexed = Object.entries(obj).map((element, index) => {
if (parseInt(element[0] != index) {
element[0] = index.toString();
}
return element;
});
