SOAP response (XML) to JSON
提问by JonoCoetzee
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 thisJavascript code, it mostly worked but returned results such as the following:
我需要使用 SOAP Web 服务，该服务自然会以 XML 格式发送响应，因为我正在开发 Appcelerator Titanium 移动应用程序，因此我更喜欢 JSON 格式的响应。在线查看后，我使用此Javascript 代码转换了响应，它主要工作但返回的结果如下：
{
"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.
当然，冒号和散列会导致问题，所以我调整了代码以在名称上做一个子字符串并在“：”之前删除任何内容，然后对生成的 JSON 进行字符串化，删除所有散列并再次解析 JSON。这对我来说有点凌乱，但我最终得到了一些可用的东西。
Here is the xmlToJson code I'm using:
这是我正在使用的 xmlToJson 代码：
// 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:
这会产生以下 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:
虽然这会返回一个我可以使用的 JSON 对象，但我更希望生成的 JSON 格式如下：
{
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
大多数情况下它不那么冗长，我可以简单地调用 json.result 来检查查询是否成功而不是 json.Body.linkAppResponse.result.text
Any help is greatly appreciated.
任何帮助是极大的赞赏。

Came up with a working solution, not any less dirty but it works and returns data in the format I want.
提出了一个可行的解决方案，虽然不那么脏，但它可以工作并以我想要的格式返回数据。
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):
控制台调试（json）：
{
linkAppResponse : {
result : {
text : true;
};
uuid : {
text : "e4f78c5f-1bc2-4b50-a749-19d733b9be3f";
};
};
}
console.debug(response):
控制台调试（响应）：
{
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.
如果有人想出更好的解决方案，我将暂时搁置这个问题。
