I am retrieving a Google Calendar Resource via their Data API, which returns the following content:
<?xml version="1.0" encoding="utf-8"?>
<atom:entry xmlns:atom="http://www.w3.org/2005/Atom" xmlns:apps="http://schemas.google.com/apps/2006">
<apps:property name='resourceId' value='CR-NYC-14-12-BR'/>
<apps:property name='resourceCommonName' value='Boardroom'/>
<apps:property name='resourceDescription' value='Conference room in New York city, building 14, floor 12, Boardroom'/>
<apps:property name='resourceType' value='CR'/>
</atom:entry>
I need to get the value of one of the fields, such as resourceId and store it in a variable. How can I parse this and obtain that value? I am using Meteor JS on the server side, which uses JavaScript. Therefore, the answer needs to use JavaScript. Thank you!
For converting xml to json use: https://github.com/buglabs/node-xml2json
parser.toJson(xml, options);
Then it's simply the issue of iterating over the values.

I am optimizing an api, therefore I need to use only data that is relevant for my analysis. I have created a route that pull out of the objects, but I just need 4 of them (account_manager, fronter, closer, management_fee and sales_date)
I am currently doing this:
you can use .find() with projection to retrieve only the relevant field
try this :
const model_CancellationKPI = await CancellationKPI.find({},{
account_manager:1,
fronter:1,
closer:1,
management_fee:1,
sales_date:1
}).sort({sales_date:-1})
I'm having a bit of issue with YQL. I'm trying to query an RSS from a URL but I get no results.
Entered this query:
select title from rss where url="http://www.spoilertv.com/feeds/posts/default/-/Aftermath"
...and instead of getting the titles as requested, the console shows:
<?xml version="1.0" encoding="UTF-8"?>
<query xmlns:yahoo="http://www.yahooapis.com/v1/base.rng"
yahoo:count="0" yahoo:created="2017-02-23T17:13:16Z" yahoo:lang="en-US">
<diagnostics>
<publiclyCallable>true</publiclyCallable>
<url execution-start-time="1" execution-stop-time="101"
execution-time="100" id="5080cef9-75a4-4356-9b08-1d68fb3d855d"><![CDATA[http://www.spoilertv.com/feeds/posts/default/-/Aftermath]]></url>
<user-time>118</user-time>
<service-time>100</service-time>
<build-version>2.0.84</build-version>
</diagnostics>
<results/>
</query>
What could be wrong?
When I made a few requests to your URL sample using YQL, I have two results, getting the results in JSON or XML it was always NULL.
According to this link:
YQL produces only xml or json. You can create rss or atom feed but it
always will be inside yql root element. So you need another one tool
to extract a feed from response. I'm using Google Apps Script for
that. It can parse and create xml/rss and uses server-side javascript
e.g:
var url = 'http://query.yahooapis.com/v1/public/yql?q=...'; // rest query to YQL table
var xml = UrlFetchApp.fetch(url).getContentText(); // this is an xml string
var root = XmlService.parse(xml).getRootElement(); // now we can modify this xml or create a new one.
What I suggest you is make the following test instead:
Check this link and follow the step #6:
Click Copy URL. From yql_news_app.html, paste the URL into the src
attribute of the second script tag as seen below which in your case
you can check as follows:
<body>
<div id='results'></div>
<escript src='https://query.yahooapis.com/v1/public/yql?q=select%20title%20from%20rss%20where%20url%3D%22http%3A%2F%2Fwww.spoilertv.com%2Ffeeds%2Fposts%2Fdefault%2F-%2FAftermath%22&diagnostics=true'>
</escript>
</body>
In your browser, press F12 (and check the Console tab). see if there're errors. If so, please update you question with the details of the results.
I am making a mobile app with Phonegap and using Wordpress as a backend. I am using Advanced Custom Fields with a Google Maps post field which returns a PHP object to the app using JSON API. My Wordpress backend sends a normal JSON object to the app, but inside that object is where a stringified PHP object is returned.
I need to convert the PHP object to a JSON object somehow on the client side(the app which is not in Wordpress). I have looked at other answers that say to use json_encode for this but my problem is that the app is just HTML/Javascript and no PHP. Is there a way to use PHP code in the middle of a Javascript function to do this? Or would it be better to change the backend so that it returns a JSON object instead of a PHP object in the first place? If so, how do I do that?
My experience in PHP is still somewhat limited so any help is appreciated.
edit: To clarify a bit more, I am using Wordpress on a separate domain from my Phonegap app and only using the JSON API plugin on the Wordpress end. I am then using jQuery Ajax calls to retrieve data from the Wordpress backend.
Also the returned PHP object looks like this: a:3:{s:7:\"address\";s:48:\"8915 W 159th St, Orland Hills, IL, United States\";s:3:\"lat\";s:17:\"41.60111599999999\";s:3:\"lng\";s:11:\"-87.8364575\";}
Another way I just thought of as well, would it be possible to just leave it as a PHP object and still read out the values from it somehow? I don't NEED it to be a JSON array, I just need a way to read the individual elements in the array in one way or another.
Here is also a tiny snippet of the JSON returned to clarify what I'm talking about.
"custom_fields": {
"location": [
"a:3:{s:7:\"address\";s:48:\"8915 W 159th St, Orland Hills, IL, United States\";s:3:\"lat\";s:17:\"41.60111599999999\";s:3:\"lng\";s:11:\"-87.8364575\";}"
]
}
That of course isn't the entire JSON object but it gives you an idea of what I'm dealing with.
I know you have a solution that works on the front end, but I still think it'd be better to fix this on the server.
Based on our conversation in the comments, I've had a closer look the code in the WordPress forum. The problem seems to be that the location field is an array of strings, not just a string. maybe_unserialize (and is_serialized, which it uses) don't handle arrays. Here's the updated code, which you should be able to drop into your theme's functions.php. I did a quick test, and it works for me.
class unserialize_php_arrays_before_sending_json {
function __construct() {
add_action( 'json_api_import_wp_post',
array( $this, 'json_api_import_wp_post' ),
10,
2 );
}
function json_api_import_wp_post( $JSON_API_Post, $wp_post ) {
foreach ( $JSON_API_Post->custom_fields as $key => $custom_field ) {
if (is_array($custom_field)) {
$unserialized_array = array();
foreach($custom_field as $field_key => $field_value) {
$unserialized_array[$field_key] = maybe_unserialize( $field_value );
}
$JSON_API_Post->custom_fields->$key = $unserialized_array;
}
else {
$JSON_API_Post->custom_fields->$key = maybe_unserialize( $custom_field );
}
}
}
}
new unserialize_php_arrays_before_sending_json();
If you're using a JSON API to retrieve the data, then why don't you deliver the data in JSON format to your app? Otherwise you seem to remove much of the point of using an API in the first place... You could of course parse that string in JavaScript if you really want to but that's a very ugly and error prone solution.
The JSON API plugin does seem to use JSON:

I need to convert the PHP object to a JSON object somehow on the client side(the app which is not in Wordpress).
This bit here leaves me confused. You do not have PHP objects on the client-side, PHP is a back-end technology. What is returned to the client is a string which can be HTML, XML, JSON, plaintext on any other form of encoding.
That said, saying you have an object $obj in PHP, you could pass it to your front-end application creating an end-point retrieve_object.php and in there:
echo json_encode($obj);
So long as that is the only thing your are outputting, you lient-side app can make a request (Eg: AJAX) to retrieve_object.php and get the json object.
BUT , and this is important (!) in doing so you serialize object properties. You will lose any PHP object method. If any object property is an object itself (EG: A DB Connection) then this will be lost too.
Hope this helps!
We are trying to create an entity that has date attributes via an odata service. Backend is an sap system. This entity has only 3 key attributes plus a bunch of other attributes. We have identified that dates in the keys are the root cause of the problem.
Keys:
Pernr type string,
begda type datetime
endda type datetime.
The code below, (which does not work), has been severely simplified when trying to troubleshoot the issue. At the moment, it reads an entity from an entity set and immediately tries to create one with exactly the same data.
Code:
var oODataModel = new sap.ui.model.odata.ODataModel("/sap/opu/odata/sap/Z_PERSONAL_DATA_SRV/");
//Test entity to be saved
var entity = null;
//Handler for read error
var handleReadE = function (oEvent){
alert("error");
};
//Handler for read success
var handleRead = function (oEvent){
//Get the data read from backend
entity = oEvent.results[0];
//Try to create a new entity with same data
oODataModel.create('/PersDataSet', entity, null, function(){
alert("Create successful");
},function(oError){
alert("Create failed", oError);
});
};
oODataModel.read("/PersDataSet", null, [], true, handleRead, handleReadE);
In the gateway error log, an xml parsing error appears. In this log, we can see the request data and it can be seen that the dates are transported with String types. These dates are defined in the service as DateTimes so the request is rejected.
Example:
<m:properties>
<d:Pernr m:type="Edm.String">00000001</d:Pernr>
<d:Endda m:type="Edm.String">9999-12-31T00:00:00</d:Endda>
<d:Begda m:type="Edm.String">1979-05-23T00:00:00</d:Begda>
When the entity is read, the backend does not send any type information. It sends like the following example:
<m:properties>
<d:Pernr>72010459</d:Pernr>
<d:Endda>9999-12-31T00:00:00</d:Endda>
<d:Begda>1876-07-21T00:00:00</d:Begda>
And, indeed, if we try to save the same info without the type=".." it works. So the problem are the incorrect types ODataModel.create adds to the xml.
My question is:
Can I tell ODataModel.create to not add this type info? It is not doing a good job inferring the types.
Can anyone share an example reading and writing dates through odata?
Thank you very much in advance.
the data returned from oODataModel.read is raw, before you post you need to parse it
var handleRead = function (oEvent){
//Get the data read from backend
entity = oEvent.results[0];
var newEntity = jQuery.extend({},entity);
delete newEntity.__metadata;
newEntity.Begda = new Date(entity.Begda);
newEntity.Endda = new Date(entity.Endda);
//Try to create a new entity with same data
oODataModel.create('/PersDataSet', newEntity, null, function(){
why not use json instead of xml?
Thanks all for the help.
We got this working accounting for the following:
The problem of the wrong types appended to the attributes comes from the read itself. The object returned by read has a __metadata attribute which describes the values. In this object the dates are set with type=edm.string, even when the service says they are DateTime. To me this is a bug of the .read function.
When trying to use the same object to save, create sees the __metatada on the entry and uses those values, producing type edm.string type for the dates. This caused the request to be rejected. Manually changing these __metadata.properties...type to Edm.DateTime makes it work.
In the end, we did the following:
Dates are parsed manually from the Odata response, creating a js Date
object from the strings in format "yyyy-mm-ddT00:00:00", to make it work with control bindings. When we want to save, the reverse is done.
The object to be created is a new object with
only the attributes we care (no __metadata)
i want to store for example a <table> (node of my DOM - build up with HTML5) using JS/JQuery. Why?
i like to renew the table but store the old table with the contained values in it. i think it would later be quick to replace an existing table (node) with an stored, than to build it up again and parse the old data.
(parse data > build table ; rewnew table: parse new data > store old table > replace old by new; later: replace new by old table)
if found for example that problem: Chrome sendrequest error: TypeError: Converting circular structure to JSON
(i tried also to convert my table via JSON save it in given localStorage)
is it recommend to store such a DOM-node in a variable or localstorage?
I'm glad for any advice.
You can store your dom in variables.
var myTable = $('#content');
Local Storage api is not work on older browsers if you want to store your dom tree on the client side you can use cookies but I don't recomend it.
