I have some string values that are retrieved from json data. I need a process of converting this strings to xml format and Post it to a url
If it's inside iPhone SDK you will have to parse the string to convert it to XML, unless you can just post the xml as-is.
Anyway. To parse the XML, you have basically two easy options:
NSXMLParser
libxml2 (my preferred choice, don't know why)
Then you can use NSURLConnection class to post the information to the desired XML. There are a lot of Stackoverflow questions already covering this issue you can search and use.
You can also look at an example here.

When a file is selected or dropped, is it automatically converted to Base64 encoding?
I need to be able to take files, convert them to strings then pass them into POST requests to our backend.
Is ng-file-upload already converting the file? Or is this something I need to manually do by calling either the:
Upload.base64DataUrl(files).then(function(urls){...});
or
Upload.dataUrl(file, boolean).then(function(url){...});
methods?
I can post the relevant code but this seems relatively straightforward. Thanks for the help!
NetSuite Restlet PDF file encoding issue
The above thread seems to be giving a solution to outputing a pdf with a NetSuite RESTlet. As far as I know, you cannot output a pdf from a restlet, so I'm very confused. I am using a restlet to generate a report and the information ultimately needs to output to a pdf so I was trying to see if there was a work around. I tried the answer code from the above thread and I got the expected error:"error code: INVALID_RETURN_DATA_FORMAT error message:Invalid data format. You should return TEXT."
Am I missing something? Is there a way to export xml to a pdf with a NetSuite RESTlet?
The thread you reference discusses how to generate a PDF file in Netsuite. If you want to return a PDF from a RESTLet you will have to return it as a member of a JSON object. e.g.:
var pdfFile = genPDF(); // base this on the sample
return{
fileName: pdfFile.getName(),
fileContent: nlapiEncrypt(pdfFile.getValue(), 'base64')
};
And then your receiver will have to create the actual file.
Recall that RESTLets are for application-to-system communications. If you are trying to return a PDF to a browser you should probably be using a Suitelet.
If this is part of a larger app and you need the RESTLet then review this post: Save base64 string as PDF at client side with JavaScript for options to display the RESTLet response.
Reading through that answer, it appears you'll need to encode/convert the PDF to string format before returning, so you'll need to use base64 encoding.
The NS method nlapiEncrypt(content, 'base64') seems like it might be a good place to start.
Another avenue to investigate, which I haven't tried, is to first save the PDF in the file cabinet, then to return a public link to that file. You'll need to make sure the file has the correct permissions.
I have a spring service which renders JSP page. Spring controller sets JSON data in a request attribute, which i use in my JSP. Can anyone tell how can i parse this JSON data. I know if my web service response was a plain json , i can parse using jsonPath. But in my case JSON is a part of JSP. So I am kinda stuck.
You mean that your JSON is inside your HTML, probably in a Javascript variable?
And I guess using a regex to retrieve the elements your interested in is not enough and that you really want the JSON string?
If so, you can first use a regex check in order to extract your JSON content from your HTML. Beware that if your JSON string is on several lines, you might have to enable some regex features such as multiline or dotall. See
Then, you can transform your regex output into a JSON tree, using the check transform step. There, you can parse the JSON string with the engine of your choice. Gatling ships with json-smart.
Another solution is to build your own check. The procedure for Gatling 2 has been described in this thread on Gatling's Google Group.
I am trying to support arbitrary unicode from a variety of international users. They have already put a bunch of data into sqlite databases on their iPhones, and now I want to capture the data into a database, then send it back to their device. Right now I am using a php page that is sending data back to from an internet mysql database. The data is saved in the mysql database properly, but when it's sent back it comes out as unicode text, such as
Frank\u00e2\u0080\u0099s iPad
instead of just
Frank's iPad
where the apostrophe should really be a curly apostrophe.
The answer posted to another question indicates that there is no built-in Cocoa methods to convert the "\u00e2\u0080\u0099" portion of the unicode string from the webserver to an NSString object. Is this correct?
That seems really surprising (and scarily disappointing), since Cocoa definitely allows input from many different Unicode characters, and I need to support any arbitrary language that I have never heard of, and all of the possible characters. I save them to and from the local sqlite database just fine now, but once I send it to a web server, then perhaps pull down different data, I want to ensure the data pulled from the web server is correctly formatted.
[...] there is no built-in Cocoa methods to convert [...]. Is this
correct?
It's not correct.
You might be interested in CFStringTransform and it's capabilities. It is a full blown ICU transformation engine, which can (also) perform your requested transformation.
See Using Objective C/Cocoa to unescape unicode characters, ie \u1234
All NSStrings are Unicode.
The problem with the “Frank\u00e2\u0080\u0099s iPad” data isn't that it's Unicode; it's that it's escaped to ASCII. “Frank’s iPad” is valid Unicode in any UTF, and is what you need.
So, you need to see whether the database is returning the data escaped or the PHP layer is escaping it at some point. If either of those is the case, fix it if you can; the PHP resource should return UTF-8/16/32. Only if that approach fails should you seek to unescape the string on the Cocoa side.
You're correct that there is no built-in way to unescape the string in Cocoa. If you get to that point, see if you can find some open-source code to do it; if not, you'll need to do it yourself, probably using NSScanner.
Check that your web service response has Content type and charset. Also that xml has encoding specified. In PHP you need to add the following before printing XML:
header('Content-type: text/xml; charset=UTF-8');
print '<?xml version="1.0" encoding="UTF-8"?>';
I guess there is just no encoding specified.
I am working with the iPhone SDK and I have to process a webservice response I receive from an external service.
The response data consists of an XML string that was UTF8-encoded to a byte array.
This byte array is converted to string
This string is put into a XML wrapper element
The wrapper is returned via an HTTP response
Therefore I need to know how to convert the response data back to the XML string it used to be. Unfortunately, I cannot change the way my response is created, so I have to deal with it somehow.
Example of the raw data I get from the webservice:
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body><ExportBytesResponse xmlns="http://knowledgepark-ag.com/webservices/">

How do I get back my old xml string representation hidden inside these raw bytes?
Any help is highly appreciated, I feel just stupid right now for not being able to come up with a solution.
Best Regards,

ExportBytesResponse is Base64 encoded, so you must first decode that node using something like this.
That will give you an NSString containing the XML. Then you can use NSXMLParser to parse your data.
