I have been programming with NSXMLParser for quite a while and lately, I came out with this error. The strangiest thing is that it only happens in debug mode. Once I load the App in Simulator and run it from Simulator (without Xcode involved), it runs fine.
The code is very straight foward, it is a simple XML parsing whose contents were loaded from the web in a separated thread.
Does anybody have alredy encoutered that error??
Thanks in advance.
EDIT:
In time I realized that this error occur when you have a bad formated XML Document. In my case, I was extracting some of the contents of an HTML Page and parsing the resulting string, but this string was not allways well formed. A little modification an voilá...
Ensure that your documents are well formed when parsing or you may have the same mistake...
PS: The parser error method did not catch this error.

In the last 2 weeks or so, I've suddenly started getting reports of users getting an error in our application saying "Expected response code 200, got 400. Unable to convert document." This is code that has been in place for years without any issue. We are using Zend Framework (GData) in conjunction with Google Docs (AuthSub).
We are logging the issue to a text file when it happens. When it gets logged, the user often tries multiple times (sometimes separated by a few seconds, other times separated by longer times) and it continues to fail. The code in question just creates a new Google document in the user's account and gives it a title (no body content).
Originally, I used this code:
// Create new document
$data = new Zend_Gdata_Docs_DocumentListEntry();
$data->setCategory(
array(new Zend_Gdata_App_Extension_Category(
"http://schemas.google.com/docs/2007#document",
"http://schemas.google.com/g/2005#kind"
)));
$data->setTitle(new Zend_Gdata_App_Extension_Title($title, null));
// Add document to your list
$test = $sharedocs->insertDocument($data, Zend_Gdata_Docs::DOCUMENTS_LIST_FEED_URI);
To experiment and see if there was an issue with that particular function, I tried creating a blank word doc and changing the code to:
$test = $sharedocs->uploadFile('/mypath/empty.doc', $title, null, Zend_Gdata_Docs::DOCUMENTS_LIST_FEED_URI);
However, I'm still seeing the "Unable to convert document" errors. They are relatively infrequent, and I am not able to reproduce the issue on my own computers here. The $title variable does not contain anything unusual (special characters, etc.).
This code was all working fine before -- is there a known issue with the Google Docs API right now? What else can I try?
NOTE: Please see my follow-up comments below, where I have identified the reproducible scenario in which this error occurs.
I had exactly the same problem, but I noticed that I could use the api to save a presentation if not a document... so, it is a terrible hack, but I try to save the document (works if the account has already been accessed)... if that fails, I save and delete a presentation and retry to save the document, which then works. Horrible, horrible, horrible hack
I am working on migrating posts from the RightNow infrastructure to another service called ZenDesk. I noticed that whenever users added files or even URL links, when I pull the xml data from RightNow it gives me a lot of weird codes like this:
{s:3:""url"";s:45:""/files/56f5be6c1/MUG_presso.pdf"";s:4:""name"";s:27:""MUG presso.pdf"";s:4:""size"";s:5:""2.1MB"";}
It wasn't too hard to write something that parses them and makes normal urls and links, but I was just wondering if this is something specific to the RightNow service, or if it is a tag system that is used. I tried googling for this but am getting some weird results so, thought stack overflow might have someone who has run into this one.
So, anyone know what these {s ;} tags are called and if there are any particular tools to use to read them?
Any answers appreciated!
This resembles partial PHP serialized data, as returned by the serialize() call. It looks like someone may have turned each " into "", which could prevent it from parsing properly. If it's wrapped with text like this before the {s: section, it's almost definitely PHP.
a:6:{i:1;a:10:{s:
These letters/numbers mean things like "an array with six elements follows", "a string of length 20 follows", etc.
You can use any PHP instance with unserialize() to handle the data. If those double-quotes are indeed returned by the API, you might need to replace :"" and ""; with " before parsing.
Parsing modules exist for other languages like Python. You can find more information in this answer.
I have a problem with parsing xml. I'm using NSXMLParser and when xml contains tag with attribute with data including quotation marks, it finishes with errorOccur and makes me very upset. Do you know about some solution,setting for xmlparser or anything where could be the problem?
Example:
<stuff attr="This is "special" text."/> ---> PROBLEM
<stuff attr="This is some text."/> ---> THIS IS OK
Thank you
The "problem" XML is not correctly formed, and as such the parser is correct in generating an error - even at the expense of making you very upset :-) Parsers are like that.
As mentioned by #D33 in the comment, the XML should use " - so if you have written the code producing the XML yourself, you can fix it there. Otherwise, you'd have to re-write the malformed XML into correct XML, and that is a slippery slope.
I am using libxml for parsing the xml. I have referred the XMLPerformance example by apple.
Following is the part of xml document which is causing a problem as it contain the " " string. i cannot just replace this " " with any other string is i am getting data in didReceiveData delegate method and i am parsing that data.
Is there any solution to resolve this issue which is coming because of special character?

To make sure your XML is well format, you can test you XML first with any online XML validator and then later you should parse that.
i am working with web services these days ,and with all xml files that i am parsing things are fine ,but with the last one the famous method "stringWithContentsOfURL" returns empty data. Why?
Most likely your URL references a non-existing file, or the content of the file can not be encoded as a NSString.
